Heliyon 2023; 9:e17692. [PMID: 37456037 PMCID: PMC10345246 DOI: 10.1016/j.heliyon.2023.e17692] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/21/2023] [Revised: 06/22/2023] [Accepted: 06/26/2023] [Indexed: 07/18/2023] Open
Abstract
Introduction Collateral formation is insufficient in some patients with acute myocardial infarction (AMI). Peripheral blood CD14++CD16+ monocytes (intermediate monocytes; IM) and vascular endothelial growth factors (VEGFs) are associated with formation of collateral circulation. Methods We enrolled 49 patients with AMI who underwent emergency percutaneous transluminal coronary intervention (PCI) (Group A) and 27 patients underwent delayed PCI 1 week after AMI (Group B). The percentage of circulating IM and levels of VEGFs in circulation were determined on day 8th. Left ventricular ejection fraction (LVEF) was measured 3 months after AMI. Results The peripheral levels of IM and serum VEGF levels on day 8th were significantly higher in patients with well-developed collateral circulation in Group A than those in Group B. The levels of circulating VEGFs in the collateral circulation (+) subgroup in Group B were lower than those in the collateral circulation (-) subgroup. Moreover, the serum VEGF-B186 levels positively correlated with IM. Conclusions Hyperacute collateral formation in patients with AMI correlated with a higher percentage of CD14++CD16+ monocytes and VEGF-B186 levels in the circulation, which was associated with milder left ventricular remodeling. The regulation of CD14++CD16+ monocytes and VEGF-B may be critical to the formation of collateral circulation and to healing AMI.

Abstract
A number of effective drugs have been developed through animal experiments, contributing to the health of many patients. In particular, the WHHL rabbit family (WHHL rabbits and its advanced strains (coronary atherosclerosis-prone WHHL-CA rabbits and myocardial infarction-prone WHHLMI rabbits) developed at Kobe University (Kobe, Japan) contributed greatly in the development of cholesterol-lowering agents. The WHHL rabbit family is animal models for human familial hypercholesterolemia, coronary atherosclerosis, and coronary heart disease. At the end of breeding of the WHHL rabbit family, this review summarizes the contribution of the WHHL rabbit family to the development of lipid-lowering agents and anti-atherosclerosis agents. Studies using the WHHL rabbit family demonstrated, for the first time in the world, that lowering serum cholesterol levels or preventing LDL oxidation can suppress the progression and destabilization of coronary lesions. In addition, the WHHL rabbit family contributed to the development of various compounds that exhibit lipid-lowering and anti-atherosclerotic effects and has also been used in studies of gene therapeutics. Furthermore, this review also discusses the causes of the increased discrepancy in drug development between the results of animal experiments and clinical studies, which became a problem in recent years, and addresses the importance of the selection of appropriate animal models used in studies in addition to an appropriate study design.

Abstract
Chronic inflammation is often accompanied by angiogenesis, the development of new blood vessels from existing ones. This vascular response is a response to chronic hypoxia and/or ischemia, but is also contributory to the progression of disorders including atherosclerosis, arthritis, and tumor growth. Proinflammatory and proangiogenic mediators and signaling pathways form a complex and interrelated network in these conditions, and many factors exert multiple effects. Inflammation drives angiogenesis by direct and indirect mechanisms, promoting endothelial proliferation, migration, and vessel sprouting, but also by mediating extracellular matrix remodeling and release of sequestered growth factors, and recruitment of proangiogenic leukocyte subsets. The role of inflammation in promoting angiogenesis is well documented, but by facilitating greater infiltration of leukocytes and plasma proteins into inflamed tissues, angiogenesis can also propagate chronic inflammation. This review examines the mutually supportive relationship between angiogenesis and inflammation, and considers how these interactions might be exploited to promote resolution of chronic inflammatory or angiogenic disorders.

Abstract
In order to find new informative predictors of myocardial infarction, we performed an analysis of genotype frequencies of polymorphic markers of SELE (rs2076059, 3832T > C), SELP (rs6131, S290 N), SELL (rs1131498, F206L), ICAM1 (rs5498, K469E), VCAM1 (rs3917010, c.928 + 420A > C), PECAM1 (rs668, V125L), VEGFA (rs35569394, -2549(18)I/D), CCL2 (rs1024611, -2518A > G), NOS3 (rs1799983, E298D), and DDAH1 (rs669173, c.303 + 30998A > G) genes in the group of Russian men with myocardial infarction (N = 315) and the control group of corresponding ethnicity, gender, and age (N = 286). Using Markov chain Monte-Carlo method (APSampler), we found genotype combinations associated with increased and decreased risk of myocardial infarction. The most significant associations were detected for PECAM1*V/V + DDAH1*C (OR = 4.17 CI 1.56-11.15 Pperm = 0.005) SELE*C + VEGFA*I + CCL2*G + VCAM1*A + NOS3*D (OR = 2.74 CI 1.66-4.52 Pperm = 2.09 × 10(-5)), and VEGFA*D/D + CCL2*A + DDAH1*C (OR = 0.44 CI 0.28-0.7 Pperm = 7.89 × 10(-5)) genotype combinations.

Abstract
Formation of arterial vasculature, here termed arteriogenesis, is a central process in embryonic vascular development as well as in adult tissues. Although the process of capillary formation, angiogenesis, is relatively well understood, much remains to be learned about arteriogenesis. Recent discoveries point to the key role played by vascular endothelial growth factor receptor 2 in control of this process and to newly identified control circuits that dramatically influence its activity. The latter can present particularly attractive targets for a new class of therapeutic agents capable of activation of this signaling cascade in a ligand-independent manner, thereby promoting arteriogenesis in diseased tissues.

Abstract
BACKGROUND AIMS The Pall Celeris system is a filtration-based point-of-care device designed to obtain a high concentrate of peripheral blood total nucleated cells (PB-TNCs). We have characterized the Pall Celeris-derived TNCs for their in vitro and in vivo angiogenic potency. METHODS PB-TNCs isolated from healthy donors were characterized through the use of flow cytometry and functional assays, aiming to assess migratory capacity, ability to form capillary-like structures, endothelial trans-differentiation and paracrine factor secretion. In a hind limb ischemia mouse model, we evaluated perfusion immediately and 7 days after surgery, along with capillary, arteriole and regenerative fiber density and local bio-distribution. RESULTS Human PB-TNCs isolated by use of the Pall Celeris filtration system were shown to secrete a panel of angiogenic factors and migrate in response to vascular endothelial growth factor and stromal-derived factor-1 stimuli. Moreover, after injection in a mouse model of hind limb ischemia, PB-TNCs induced neovascularization by increasing capillary, arteriole and regenerative fiber numbers, with human cells detected in murine tissue up to 7 days after ischemia. CONCLUSIONS The Pall Celeris system may represent a novel, effective and reliable point-of-care device to obtain a PB-derived cell product with adequate potency for therapeutic angiogenesis.

Abstract
In the event of obstructive coronary artery disease, collateral arteries have been deemed an alternative blood
source to preserve myocardial tissue perfusion and function. Monocytes play an important role in modulating this process,
by local secretion of growth factors and extracellular matrix degrading enzymes. Extensive efforts have focused on developing
compounds for augmenting the growth of collateral vessels (arteriogenesis). Nonetheless, clinical trials investigating
the therapeutic potential of these compounds resulted in disappointing outcomes. Previous studies focused on developing
compounds that stimulated collateral vessel growth by enhancing monocyte survival and activity. The limited success
of these compounds in clinical studies, led to a paradigm shift in arteriogenesis research. Recent studies have shown genetic
heterogeneity between CAD patients with sufficient and insufficient collateral vessels. The genetic predispositions in
patients with poorly developed collateral vessels include overexpression of arteriogenesis inhibiting signaling pathways.
New directions of arteriogenesis research focus on attempting to block such inhibitory pathways to ultimately promote arteriogenesis.
Methods to detect collateral vessel growth are also critical in realizing the therapeutic potential of newly developed
compounds. Traditional invasive measurements of intracoronary derived collateral flow index remain the gold
standard in quantifying functional capacity of collateral vessels. However, advancements made in hybrid diagnostic imaging
modalities will also prove to be advantageous in detecting the effects of pro-arteriogenic compounds.

Abstract
Background In pathological situations, such as acute myocardial infarction, disorders of
motility of the proximal gut can trigger symptoms like nausea and vomiting. Acute
myocardial infarction delays gastric emptying (GE) of liquid in rats. Objective Investigate the involvement of the vagus nerve, α 1-adrenoceptors, central nervous
system GABAB receptors and also participation of paraventricular
nucleus (PVN) of the hypothalamus in GE and gastric compliance (GC) in infarcted
rats. Methods Wistar rats, N = 8-15 in each group, were divided as INF group and sham (SH) group
and subdivided. The infarction was performed through ligation of the left anterior
descending coronary artery. GC was estimated with pressure-volume curves. Vagotomy
was performed by sectioning the dorsal and ventral branches. To verify the action
of GABAB receptors, baclofen was injected via icv
(intracerebroventricular). Intravenous prazosin was used to produce chemical
sympathectomy. The lesion in the PVN of the hypothalamus was performed using a
1mA/10s electrical current and GE was determined by measuring the percentage of
gastric retention (% GR) of a saline meal. Results No significant differences were observed regarding GC between groups; vagotomy
significantly reduced % GR in INF group; icv treatment with baclofen significantly
reduced %GR. GABAB receptors were not conclusively involved in delaying
GE; intravenous treatment with prazosin significantly reduced GR% in INF group.
PVN lesion abolished the effect of myocardial infarction on GE. Conclusion Gastric emptying of liquids induced through acute myocardial infarction in rats
showed the involvement of the vagus nerve, alpha1- adrenergic receptors and
PVN.

Abstract
C-X-C motif ligand 10 (CXCL10), or interferon-inducible protein-10, is a small chemokine belonging to the CXC chemokine family. Its members are responsible for leukocyte trafficking and act on tissue cells, like endothelial and vascular smooth muscle cells. CXCL10 is secreted by leukocytes and tissue cells and functions as a chemoattractant, mainly for lymphocytes. After binding to its receptor CXCR3, CXCL10 evokes a range of inflammatory responses: key features in cardiovascular disease (CVD). The role of CXCL10 in CVD has been extensively described, for example for atherosclerosis, aneurysm formation, and myocardial infarction. However, there seems to be a discrepancy between experimental and clinical settings. This discrepancy occurs from differences in biological actions between species (e.g. mice and human), which is dependent on CXCL10 signaling via different CXCR3 isoforms or CXCR3-independent signaling. This makes translation from experimental to clinical settings challenging. Furthermore, the overall consensus on the actions of CXCL10 in specific CVD models is not yet reached. The purpose of this review is to describe the functions of CXCL10 in different CVDs in both experimental and clinical settings and to highlight and discuss the possible discrepancies and translational difficulties. Furthermore, CXCL10 as a possible biomarker in CVD will be discussed.

Abstract
Occlusion of the main arterial route redirects blood flow to the collateral circulation. We previously reported that macrophages genetically modified to express low levels of prolyl hydroxylase domain protein 2 (PHD2) display an arteriogenic phenotype, which promotes the formation of collateral vessels and protects the skeletal muscle from ischaemic necrosis. However, the molecular mechanisms underlying this process are unknown. Here, we demonstrate that femoral artery occlusion induces a switch in macrophage phenotype through angiopoietin-1 (ANG1)-mediated Phd2 repression. ANG blockade by a soluble trap prevented the downregulation of Phd2 expression in macrophages and their phenotypic switch, thus inhibiting collateral growth. ANG1-dependent Phd2 repression initiated a feed-forward loop mediated by the induction of the ANG receptor TIE2 in macrophages. Gene silencing and cell depletion strategies demonstrate that TIE2 induction in macrophages is required to promote their proarteriogenic functions, enabling collateral vessel formation following arterial obstruction. These results indicate an indispensable role for TIE2 in sustaining in situ programming of macrophages to a proarteriogenic, M2-like phenotype, suggesting possible new venues for the treatment of ischaemic disorders.

Abstract
Coronary heart disease is still the leading cause of death in industrialized nations. Reduction of infarct size after acute myocardial infarction and, in addition, improvement of myocardial function and perfusion in acute and chronic myocardial ischemia would enhance cardiac survival. Thymosin β4, a 43-amino acid water-soluble peptide with pleiotropic abilities seems to be a promising candidate for the treatment of ischemic heart disease. During cardiac development, thymosin β4 is essential for vascularization of the myocardium, by targeting all three parts of vessel development, that is, vasculogenesis, angiogenesis, and arteriogenesis. In the adult, thymosin β4 is capable of inducing angiogenesis via activation of survival kinases in an actin-dependent and -independent manner. In addition, thymosin β4 has anti-inflammatory properties by reducing NF-κB p65 activation. These protective effects are further enhanced through increased myocyte and endothelial cell survival accompanied by differentiation of epicardial progenitor cells.

Abstract
Arteriosclerotic vascular disease is the most common cause of death and a major cause of disability in the developed world. Adverse outcomes of arteriosclerotic vascular disease are related to consequences of tissue ischemia and necrosis affecting the heart, brain, limbs, and other organs. Collateral artery growth or arteriogenesis occurs naturally and can help restore perfusion to ischemic tissues. Understanding the mechanisms of collateral artery growth may provide therapeutic options for patients with ischemic vascular disease. In this review, we examine the evidence for a role of monocytes and macrophages in collateral arteriogenesis.

Abstract
BACKGROUND Up to 5% of the population may have a brain aneurysm. If the brain aneurysm ruptures, there is >50% mortality, and more than one third of survivors are dependent. Brain aneurysms detected before rupture can be treated to prevent rupture, or ruptured aneurysms can be treated to prevent rerupture. Endovascular coiling of brain aneurysms is the treatment of choice for some aneurysms; however, up to one quarter of aneurysms may recur. The coiled aneurysms that do not recur are characterized by inflammatory intra-aneurysmal tissue healing; therefore, we studied the biology of this process, specifically the role of monocyte chemotactic protein-1 (MCP-1), a cytokine known for tissue healing. METHODS AND RESULTS We created coils with a 50:50 poly-dl-lactic glycolic acid (PLGA) coating that released MCP-1 at 3 different doses (100 μg/mL, 1 mg/mL, and 10 mg/mL) and performed a dose-response study for effect on intra-aneurysmal tissue healing in a murine carotid aneurysm model. We then demonstrated that MCP-1 (100 μg/mL)-releasing coils promote significantly greater aneurysm tissue in-growth than bare platinum or PLGA-only coils. We show that MCP-1 recruits the migration of fibroblasts, macrophages, smooth muscle cells, and endothelial cells in vitro in cell migration assays and in vivo in murine carotid aneurysms. Using gfp(+) bone marrow-transplant chimeric mice, we demonstrate that the MCP-1-recruited fibroblasts and macrophages are derived from the bone marrow. We demonstrate that this MCP-1-mediated vascular inflammatory repair occurs via a macrophage inflammatory protein (MIP)-1α- and MIP-2-dependent pathway. MCP-1 released from coiled murine aneurysms causes significant upregulation of MIP-1α and MIP-2 expression by cytokine array assay. Blocking MIP-1α and MIP-2 with antagonist antibody causes a significant decrease in MCP-1-mediated intra-aneurysmal tissue healing. CONCLUSION Our findings suggest that MCP-1 has a critical role in promoting inflammatory intra-aneurysmal tissue healing in an MIP-1α- and MIP-2-dependent pathway.

Abstract
Rationale:
Positive outward remodeling of pre-existing collateral arteries into functional conductance arteries, arteriogenesis, is a major endogenous rescue mechanism to prevent cardiovascular ischemia. Collateral arterial growth is accompanied by expression of kinin precursor. However, the role of kinin signaling via the kinin receptors (B1R and B2R) in arteriogenesis is unclear.
Objective:
The purpose of this study was to elucidate the functional role and mechanism of bradykinin receptor signaling in arteriogenesis.
Methods and Results:
Bradykinin receptors positively affected arteriogenesis, with the contribution of B1R being more pronounced than B2R. In mice, arteriogenesis upon femoral artery occlusion was significantly reduced in B1R mutant mice as evidenced by reduced microspheres and laser Doppler flow perfusion measurements. Transplantation of wild-type bone marrow cells into irradiated B1R mutant mice restored arteriogenesis, whereas bone marrow chimeric mice generated by reconstituting wild-type mice with B1R mutant bone marrow showed reduced arteriogenesis after femoral artery occlusion. In the rat brain 3-vessel occlusion arteriogenesis model, pharmacological blockade of B1R inhibited arteriogenesis and stimulation of B1R enhanced arteriogenesis. In the rat, femoral artery ligation combined with arterial venous shunt model resulted in flow-driven arteriogenesis, and treatment with B1R antagonist R715 decreased vascular remodeling and leukocyte invasion (monocytes) into the perivascular tissue. In monocyte migration assays, in vitro B1R agonists enhanced migration of monocytes.
Conclusions:
Kinin receptors act as positive modulators of arteriogenesis in mice and rats. B1R can be blocked or therapeutically stimulated by B1R antagonists or agonists, respectively, involving a contribution of peripheral immune cells (monocytes) linking hemodynamic conditions with inflammatory pathways.

Abstract
Background Glucagon-like peptide-1(GLP-1), released from enteroendocrine cells of the intestine, exerted cardiovascular protective effect. Circulating endothelial progenitor cells (EPCs) play an important role in maintaining endothelial integrity regulating neovascularization and reendothelialization after endothelial injury. Vascular endothelial growth factor (VEGF) is an important cytokine in the process of EPCs vascular differentiation and proliferation. Material/Methods This study was designed to investigate the association between VEGF changes and the proliferation/differentiation function of EPCs in the presence of GLP-1. Results We demonstrated that GLP-1 markedly enhanced the EPCs proliferation and expression of EC-specific markers, and simultaneously upregulated VEGF secretion in EPCs. Exogenous VEGF augmented EPCs proliferation/differentiation abilities in a dose-dependent manner. However, all of the beneficial effects of GLP-1 were suppressed by anti-VEGFmAb or the KDR-specific tyrosine kinase inhibitor SU1498. Conclusions These findings suggest that GLP-1 improves VEGF generation, which contributed to improvement of EPCs biological function, partly by tyrosine kinase KDR. VEGF is a necessary intermediate, mediating the effects of GLP-1 on EPCs. These changes offer a novel explanation that upregulation EPCs bioactivities may be one of the mechanisms of GLP-1 cardiovascular protective effect.

Abstract
Patients suffering from both diabetes and PAD (peripheral arterial disease) are at risk of developing critical limb ischaemia and ulceration, and potentially requiring limb amputation. In addition, diabetes complicates surgical treatment of PAD and impairs arteriogenesis. Arteriogenesis is defined as the remodelling of pre-existing arterioles into conductance vessels to restore the perfusion distal to the occluded artery. Several strategies to promote arteriogenesis in the peripheral circulation have been devised, but the mechanisms through which diabetes impairs arteriogenesis are poorly understood. The present review provides an overview of the current literature on the deteriorating effects of diabetes on the key players in the arteriogenesis process. Diabetes affects arteriogenesis at a number of levels. First, it elevates vasomotor tone and attenuates sensing of shear stress and the response to vasodilatory stimuli, reducing the recruitment and dilatation of collateral arteries. Secondly, diabetes impairs the downstream signalling of monocytes, without decreasing monocyte attraction. In addition, EPC (endothelial progenitor cell) function is attenuated in diabetes. There is ample evidence that growth factor signalling is impaired in diabetic arteriogenesis. Although these defects could be restored in animal experiments, clinical results have been disappointing. Furthermore, the diabetes-induced impairment of eNOS (endothelial NO synthase) strongly affects outward remodelling, as NO signalling plays a key role in several remodelling processes. Finally, in the structural phase of arteriogenesis, diabetes impairs matrix turnover, smooth muscle cell proliferation and fibroblast migration. The review concludes with suggestions for new and more sophisticated therapeutic approaches for the diabetic population.

Abstract
BACKGROUND Monocyte chemoattractant protein-1 (MCP-1) facilitates the recruitment of monocytes/macrophages into vascular intima, and it is probably involved in the regulation of other signaling pathways relevant to the pathogenesis of arteriosclerosis and metabolic disturbances. However, chemokines are redundant. Consequently, the protective effect of MCP-1 deficiency may be mediated by changes in other cytokine signals. METHODS AND RESULTS Changes in the pattern of gene expression in the aorta were evaluated in LDLr(-/-) and MCP-1(-/-) LDLr(-/-) mice fed either chow or Western-style diet. Functional analyses were used to characterize the pathways affected and to identify biological processes in which MCP-1 may play an additional role. Some data also suggest that MCP-5 may act as a surrogate for MCP-1 deletion. Arteriosclerosis lesion and plaque composition are associated with enrichment in the cytokine-cytokine receptor interaction pathway. CONCLUSIONS There is a complex network of interactions linking MCP-1 and other cytokines. The lack of MCP-1 limits the aortic response to atherogenic stimuli, but does not completely protect against neointima formation. Activation of alternative inflammatory pathways in the vascular wall in response to MCP-1 deficiency should be considered to fully understand the actual role of this chemokine.

Abstract
Ovariectomy (OVX)-induced estrogen withdrawal resulted in both bone loss and an increase in fat. We observed elevated osteoclast (OC) formation by bone marrow-derived macrophages treated with medium conditioned by fats from OVX mice, but not from sham-operated mice. Fats from OVX mice expressed and secreted higher levels of monocyte chemoattractant protein-1 (MCP-1) than those from sham-operated mice. Increased fat resulting from estrogen deficiency is thus responsible for bone loss due to enhanced OC formation, which is, at least partly, a consequence of elevated MCP-1 production.

Abstract
Transplantation of endothelial cells (EC) for therapeutic vascularization is a promising approach in tissue engineering but has yet to be proven effective in clinical trials. This cell-based therapy is hindered by significant apoptosis of EC upon transplantation as well as poor recruitment of host mural cells to stabilize nascent vessels. Here, we address these deficiencies by augmenting endothelial cell transplantation with dual delivery of vascular endothelial growth factor (VEGF) - to improve survival of transplanted EC - and monocyte chemotactic protein-1 (MCP-1) - to induce mural cell recruitment. We produced alginate microparticles that deliver VEGF and MCP-1 with distinct release kinetics and that can be integrated into a collagen/fibronectin (protein) gel construct for delivery of EC. Combined delivery of VEGF and MCP-1 increased functional vessel formation from transplanted EC and also led to a higher number of smooth muscle cell-invested vessels than did EC therapy alone. Despite the well-known role of MCP-1 in inflammation, these beneficial effects were accomplished without a long-term increase in monocyte/macrophage recruitment or a shift to a pro-inflammatory (M1) macrophage phenotype. Overall, these data suggest a potential benefit of combined delivery of MCP-1 and VEGF from EC-containing hydrogels as a strategy for therapeutic vascularization.

Abstract
BACKGROUND Most current animal models of hindlimb ischemia use acute arterial occlusion that does not accurately reflect the pathogenesis of gradual arterial occlusion in humans. We, therefore, developed the first mouse model of gradual arterial occlusion and tested the hypothesis that the mechanisms regulating blood flow recovery are critically dependent on the rate of arterial occlusion. METHODS Gradual arterial occlusion was induced by placing ameroid constrictors on the proximal and distal left femoral artery, and ligating the femoral arterial branches (n = 36). Acute arterial occlusion was accomplished by excising the left femoral artery (n = 36). The blood flow recovery was studied by laser Doppler imaging. Differential gene expression between these two models was assessed by quantitative real-time polymerase chain reactions (PCR). Inflammatory and progenitor cells recruitment were determined by immunohistochemistry. RESULTS We found that hypoxia-related genes increased significantly in the calf, but not in the thigh, after gradual and acute femoral arterial occlusion (P < .05). Shear-stress dependent genes and inflammatory genes were upregulated immediately in the thigh only after acute femoral arterial occlusion (P < .05). These differences in gene expression were consistent with increased SDF-1alpha expression, recruitment of macrophages and hemangiocytes, and higher blood flow recovery after acute arterial occlusion than after gradual arterial occlusion (P < .05). CONCLUSION This is the first study to show the mechanisms that regulate blood flow recovery are critically dependent on the rate of arterial occlusion. This novel model of gradual arterial occlusion may more closely resemble the human diseases, and may provide more accurate mechanistic insights for creating novel molecular therapies.

Abstract
Objective—
Osteopontin (OPN) is a highly phosphorylated extracellular matrix glycoprotein that is involved in a diversity of biological processes. In the vascular wall, OPN is produced by monocytes/macrophages, endothelial cells, and smooth muscle cells, and it is thought to mediate adhesion, migration, and survival of these cell types. In this study, we hypothesized that OPN plays a critical role in recovery from limb ischemia.
Methods and Results—
We induced hind limb ischemia in wild-type and OPN
−/−
mice. OPN
−/−
mice exhibited significantly delayed recovery of ischemic foot perfusion as determined by LDPI, impaired collateral vessel formation as measured using micro-CT, and diminished functional capacity of the ischemic limb. In the aortic ring assay, normal endothelial cell sprouting was found in OPN
−/−
mice. However, OPN
−/−
peritoneal monocytes/macrophages were found to possess significantly reduced migration in response to chemoattraction.
Conclusions—
This study provides evidence that a definitive biological role exists for OPN during ischemic limb revascularization, and we have suggested that this may be driven by impaired monocyte/macrophage migration in OPN
−/−
mice. These findings provide the first in vivo evidence that OPN may be a key regulator in postnatal vascular growth.

Abstract
AIMS The effects of ischemia and hypercholesterolemia on the function and morphological adaptation of the rabbit hindlimb were assessed. METHODS In rabbits on normal or cholesterol diet, experiments were performed on days 0-28 following bilateral femoral artery ligation. Calf blood pressure (C(BP)), exercise tolerance, flow reserve, agonist vasodilatation, angiography and capillary density were examined and modeled. RESULTS C(BP) decreased markedly post-ligation and returned to 41 and 68% of baseline by days 7 and 28. Exercise tolerance was attenuated 40% and flow reserve 50-60% on day 7, with recovery by day 28. Ligation caused decreases in 5-hydroxytryptamine-induced dilatation, while adenosine and acetylcholine responses were unaffected. Hypercholesterolemia attenuated acetylcholine-elicited dilatation. There was marked loss of adenosine dilatation on days 7-14 in the ligation plus hypercholesterolemia group. Ligation caused a doubling in the number of medium-sized collateral arteries. Hypercholesterolemia, either alone or combined with ligation, greatly augmented small vessel density. Capillary density was unaltered by any treatment. CONCLUSIONS The rabbit hindlimb shows a remarkable ability to recover its muscle function through vascular adaptation and remodeling 4 weeks following ligation, with or without hypercholesterolemia. Exercise tolerance, flow reserve and vascular reactivity were mainly restored 28 days post-ligation.

Abstract
In the course of peripheral artery occlusive disease, blood flow to peripheral tissue progressively decreases in a substantial portion of patients, leading to insufficient oxygenation and to the occurrence of claudication or critical limb ischemia. Arteriogenesis (collateral artery growth) is a powerful natural mechanism by which large conductance vessels develop that circumvent sites of obstruction. Promising experimental data on both hypoxia-driven angiogenesis as well as monocyte-orchestrated arteriogenesis have raised high hopes for clinical application. Both endothelial growth factors to stimulate angiogenesis (i.e., capillary growth) and monocyte-attracting or -activating substances to stimulate arteriogenesis, have been proposed as potential new therapeutic agents. However, transferring the promising experimental results into clinical practice has been more cumbersome than initially anticipated. Some recent clinical studies are now focusing more specifically on the stimulation of arteriogenesis. This review will critically evaluate the results of preclinical and clinical investigations on the stimulation of vascular growth, focusing specifically on the peripheral circulation.

Abstract
OBJECTIVE The role of ischemia in collateral vessel development (arteriogenesis) is a contentious issue that cannot be addressed using mammalian models. To investigate this, we developed models of arteriogenesis using the zebrafish embryo, which gains sufficient oxygenation via diffusion to prevent ischemia in response to arterial occlusion. METHODS AND RESULTS We studied gridlock mutant embryos that suffer a permanently occluded aorta and show that these restore aortic blood flow by collateral vessels. We phenocopied gridlock mutants by laser-induced proximal aortic occlusion in transgenic Fli1:eGFP/GATA1:dsRED embryos. Serial imaging showed these restore aortic blood flow via collateral vessels by recruitment of preexisting endothelium in a manner similar to gridlocks. Collateral aortic blood flow in gridlock mutants was dependent on both nitric oxide and myeloid cells. Confocal microscopy of transgenic gridlock/Fli1:eGFP mutants demonstrated no aberrant angiogenic response to the aortic occlusion. qPCR of HIF1alpha expression confirmed the absence of hypoxia in this model system. CONCLUSIONS We conclude that NO and myeloid cell-dependent collateral vessel development is an evolutionarily ancient response to arterial occlusion and is able to proceed in the absence of ischemia.

Abstract
OBJECTIVES We investigated whether retroinfusion of liposomal endothelial nitric oxide synthase (eNOS) S1177D complementary deoxyribonucleic acid (cDNA) would affect neovascularization and function of the ischemic myocardium. BACKGROUND Recently, we demonstrated the feasibility of liposomal eNOS cDNA transfection via retroinfusion in a model of acute myocardial ischemia/reperfusion. In the present study, we used this approach to target a phosphomimetic eNOS construct (eNOS S1177D) into chronic ischemic myocardium in a pig model of hibernation. METHODS Pigs (n = 6/group) were subjected to percutaneous implantation of a reduction stent graft into the left anterior descending artery (LAD), inducing total occlusion within 28 days. At day 28, retroinfusion of saline solution containing liposomal green fluorescent protein or eNOS S1177D cDNA (1.5 mg/animal, 2 x 10 min) was performed. Furthermore, L-nitroarginine-methylester (L-NAME) was applied orally from day 28, where indicated. At day 28 and day 49, fluorescent microspheres were injected into the left atrium for perfusion analysis. Regional functional reserve (at atrial pacing 140/min) was assessed at day 49 by subendocardial segment shortening (SES) (sonomicrometry, percent of ramus circumflexus region). RESULTS The eNOS S1177D overexpression increased endothelial cell proliferation as well as capillary and collateral growth at day 49. Concomitantly, eNOS S1177D overexpression enhanced regional myocardial perfusion from 62 +/- 4% (control) to 77 +/- 3% of circumflex coronary artery-perfused myocardium, unless L-NAME was co-applied (69 +/- 5%). Similarly, eNOS S1177D cDNA improved functional reserve of the LAD (33 +/- 5% vs. 7 +/- 3% of circumflex coronary artery-perfused myocardium), except for L-NAME coapplication (13 +/- 6%). CONCLUSIONS Retroinfusion of eNOS S1177D cDNA induces neovascularization via endothelial cell proliferation and collateral growth. The resulting gain of perfusion enables an improved functional reserve of the hibernating myocardium.

Abstract
Repair of diseased or injured myocardium by cell-based therapies is likely to require a multi-pronged approach. New myocytes will need to be generated, integrated with existing myocardial tissue, and perfused with a newly acquired vascular system. There are many potential avenues to achieve this goal, and optimizing repair is likely to require a synthetic therapeutic approach. In this review, we discuss several issues to be considered in cell-based cardiac repair, some progress which has been made toward this goal, and future directions.

Abstract
BACKGROUND The development of collateral circulation plays an important role in protecting tissues from ischemic damage, and its stimulation has emerged as one of principal approaches to therapeutic angiogenesis. Clinical observations have documented substantial differences in the extent of collateralization among patients with coronary artery disease (CAD), with some individuals demonstrating marked abundance and others showing nearly complete absence of these vessels. Recent studies have suggested that circulating monocytes play a major role in collateral growth. The present study was undertaken to determine transcriptional profiles of circulating monocytes in CAD patients with different extents of collateral growth. METHODS AND RESULTS Monocyte transcriptomes from CAD patients with and without collateral vessels were obtained by use of high-throughput expression profiling. Using a newly developed redundancy-based data mining method, we have identified a set of molecular markers characteristic of a "noncollateralgenic" phenotype. Moreover, we show that these transcriptional abnormalities are independent of the severity of CAD or any other known clinical parameter thought to affect collateral development and correlated with protein expression levels in monocytes and plasma. CONCLUSIONS Monocyte transcription profiling identifies sets of patients with extensive versus poorly developed collateral circulation. Thus, genetic factors may heavily influence coronary collateral vessel growth in CAD and affect prognosis and response to therapeutic interventions.

Abstract
Vascular endothelial growth factor (VEGF) is a key regulator of blood vessel formation during both vasculogenesis and angiogenesis. The prolonged expression of VEGF in the normoperfused skeletal muscles of adult rodents after gene transfer using AAV vectors induces the formation of a large set of new capillaries and small arteries. Notably, this process is accompanied by the massive infiltration by mononuclear cells. This observation raises the possibility that these cells might represent circulating progenitors that are eventually incorporated in the newly formed vessels. Here we explore this possibility by exploiting 4 different experimental models based on (a) the transplantation of male bone marrow into female recipients; (b) the transplantation of Tie2-GFP transgenic bone marrow; (c) the transplantation of bone marrow in the presence of erythropoietin (EPO), a mobilizer of endothelial progenitor cells (EPCs); and (d) the reimplantation of ex vivo–expanded EPCs. In all 4 models, VEGF acted as a powerful attractor of bone marrow–derived mononuclear cells, bearing different myeloid and endothelial markers proper of the EPCs to the sites of neovascularization. In no case, however, were the attracted cells incorporated in the newly formed vasculature. These observations indicate that new blood vessel formation induced by VEGF occurs through bona fide sprouting angiogenesis; the contribution of the infiltrating bone marrow–derived cells to this process still remains enigmatic.

Abstract
Cardiovascular and cerebrovascular disease represent the two most common causes of mortality and morbidity in western countries, and the treatment for these is generally by the mechanical restoration of blood flow in the affected tissues. Stimulation of collateral artery growth (arteriogenesis) provides a potential alternative option for the treatment of patients suffering from occlusive artery disease. Therefore, researchers have established several angiogenesis and arteriogenesis animal models to investigate basic mechanisms and pharmacological modulation of collateral artery growth. The authors highlight the most important aspects of vascular growth, discuss different methods and techniques for examining the process, and review the advantages and disadvantages associated with the animal models available for studying this phenomenon.

Abstract
BACKGROUND Monocyte chemotactic protein-1 (MCP-1) is important in macrophage recruitment and activation. However, the magnitude and temporal sequence of MCP-1 expression in relation to tissue injury and regeneration following ischemic injury remains unknown. MATERIALS AND METHODS Hind limb ischemia was induced by femoral artery excision (FAE) in C57Bl/6J mice; a sham surgery was performed on the contralateral leg. Muscle lysates were used to measure MCP-1 and activities of creatine kinase, lactate dehydrogenase, and myeloperoxidase. Histology and immunohistochemistry were used to localize inflammation and MCP-1. RESULTS FAE resulted in a prolonged period of ischemia and the administration of MCP-1 did not alter the restoration of perfusion. One day after femoral artery excision, extensive muscle necrosis and neutrophils were prevalent throughout the musculature of the lower leg. By 3 days, a mononuclear cell infiltrate predominated in association with robust muscle regeneration as indicated by myoD expression. Concomitantly, myeloperoxidase was maximally increased. Muscle enzymes (creatine kinase and lactate dehydrogenase) were maximally decreased within 3 days and returned to baseline levels by day 14, a time course consistent with injury and regeneration observed by histology. In parallel with these inflammatory and regenerative events, MCP-1 in muscle was maximally increased at day 3. By immunohistochemistry, MCP-1 was within vascular endothelial cells and infiltrating macrophages in areas of ischemic injury. CONCLUSIONS The transient increases and selective tissue distribution of MCP-1 during early inflammation and muscle regeneration support the hypothesis that this cytokine participates in the early reparative events preceding the restoration of vascular perfusion following ischemic injury.

Abstract
OBJECTIVE Peripheral blood contains primitive (stem cell-like) and monocytic-like endothelial cell progenitors. Diabetes apparently converts these primitive progenitors, from a pro-angiogenic to anti-angiogenic phenotype. Monocytic progenitors seem to be less affected by diabetes, but potential pro-angiogenic activities of freshly isolated monocytic progenitors remain unexplored. We compared the ability of primitive and monocytic endothelial cell progenitors to stimulate vascular growth and healing in diabetes and investigated potential molecular mechanisms through which the cells mediate their in vivo effects. METHODS AND RESULTS Human CD34+ primitive progenitors and CD14+ monocytic progenitors were injected locally into the ischemic limbs of diabetic mice. CD14+ cell therapy improved healing and vessel growth, although not as rapidly or effectively as CD34+ cell treatment. Western blot analysis revealed that cell therapy modulated expression of molecules in the VEGF, MCP-1, and angiopoietin pathways. CONCLUSIONS Injection of freshly isolated circulating CD14+ cells improves healing and vascular growth indicating their potential for use in acute clinical settings. Importantly, CD14+ cells could provide a therapeutic option for people with diabetes, the function of whose CD34+ cells may be compromised. At least some progenitor-induced healing probably is mediated through increased sensitivity to VEGF and increases in MCP-1, and possibly modulation of angiopoietins.

Abstract
BACKGROUND Current experimental models of critical limb ischemia are based on acute ischemia rather than on chronic ischemia. Human peripheral vascular disease is largely a result of chromic ischemia. We hypothesized that a model of chronic hindlimb ischemia would develop more collateral arteries, more blood flow, and less necrosis and inflammation than would acute hindlimb ischemia. We therefore developed a rat model of chronic hindlimb ischemia and compared the effects of chronic ischemia with those of acute ischemia on hindlimb skeletal muscle. METHODS Acute or chronic ischemia was induced in 36 male Sprague-Dawley rats. Chronic ischemia caused blood flow, as measured by laser Doppler scanning and confirmed by muscle oxygen tension measurements, to gradually decrease over 1 to 2 weeks after operation. RESULTS Histologic analysis showed chronic hindlimb ischemia better preserved muscle mass and architecture and stimulated capillary angiogenesis, while lacking the muscle necrosis and inflammatory cell infiltrate seen after acute ischemia. Surprisingly, the chronic ischemia group recovered dermal blood flow more slowly and less completely than did the acute ischemia group, as measured by laser Doppler (0.66 +/- 0.02 vs 0.76 +/- 0.04, P < .05) and tissue oxygen tension (0.61 +/- 0.06 vs 0.81 +/- 0.05, P < .05) at 40 days postoperatively. Consistent with poorer blood flow recovery, chronic ischemia resulted in smaller diameter collateral arteries (average diameter of the five largest collaterals on angiogram was 0.01 +/- 0.0003 mm vs 0.013 +/- 0.0007 mm for acute, P < .005 at 40 days postoperatively). Acute ischemia resulted in decreased tissue concentrations of vascular endothelial growth factor (VEGF) (0.96 +/- 0.23 pg/mg of muscle for acute vs 4.4 +/- 0.75 and 4.8 +/- 0.75 pg/mg of muscle for unoperated and chronic, respectively, P < .05 acute vs unoperated), and in increased tissue concentrations of interleukin (IL)-1beta (7.3 +/- 4.0 pg/mg of muscle for acute vs undetectable and 1.7 +/- 1.6 pg/mg of muscle for unoperated and chronic, respectively, P < 0.05 acute vs unoperated). CONCLUSIONS We describe here the first model of chronic hindlimb ischemia in the rat. Restoration of blood flow after induction of hindlimb ischemia is dependent on the rate of arterial occlusion. This difference in blood flow recovery correlates with distinct patterns of muscle necrosis, inflammatory cell infiltration, and cytokine induction in the ischemic muscle. Differences between models of acute and chronic hindlimb ischemia may have important consequences for future studies of mechanisms regulating arteriogenesis and for therapeutic approaches aimed at promoting arteriogenesis in humans suffering from critical limb ischemia. CLINICAL RELEVANCE Despite the substantial clinical differences between acute and chronic ischemia, researchers attempting to develop molecular therapies to treat critical limb ischemia have only tested those therapies in experimental models of acute hindlimb ischemia. We present here a novel model of chronic hindlimb ischemia in the rat. We further demonstrate that when hindlimb ischemia is developed chronically, collateral artery development is poorer than when hindlimb ischemia is developed acutely. These findings suggest that further tests of molecular therapies for critical limb ischemia should be performed in chronic hindlimb ischemia models rather than in acute hindlimb ischemia models.

Abstract
Infusion of different hematopoietic stem cell populations and ex vivo expanded endothelial progenitor cells augments neovascularization of tissue after ischemia and contributes to reendothelialization after endothelial injury, thereby, providing a novel therapeutic option. However, controversy exists with respect to the identification and the origin of endothelial progenitor cells. Overall, there is consensus that endothelial progenitor cells can derive from the bone marrow and that CD133/VEGFR2 cells represent a population with endothelial progenitor capacity. However, increasing evidence suggests that there are additional bone marrow-derived cell populations (eg, myeloid cells, "side population" cells, and mesenchymal cells) and non-bone marrow-derived cells, which also can give rise to endothelial cells. The characterization of the different progenitor cell populations and their functional properties are discussed. Mobilization and endothelial progenitor cell-mediated neovascularization is critically regulated. Stimulatory (eg, statins and exercise) or inhibitory factors (risk factors for coronary artery disease) modulate progenitor cell levels and, thereby, affect the vascular repair capacity. Moreover, recruitment and incorporation of endothelial progenitor cells requires a coordinated sequence of multistep adhesive and signaling events including adhesion and migration (eg, by integrins), chemoattraction (eg, by SDF-1/CXCR4), and finally the differentiation to endothelial cells. This review summarizes the mechanisms regulating endothelial progenitor cell-mediated neovascularization and reendothelialization.

Abstract
Angiogenesis is a complex process requiring integration of multiple signals in order to achieve successful development of the new vasculature. While individual activities of numerous growth factors are well understood, the integration of their signaling at the cellular and tissue level is just beginning to be appreciated. This review focuses on these two process using vascular endothelial growth factor (VEGF) and fibroblast growth factor 2 (FGF2) as examples.

Abstract
Our increasing appreciation of the importance of inflammation in vascular disease has focused attention on the molecules that direct the migration of leukocytes from the blood stream to the vessel wall. In this review, we summarize roles of the chemokines, a family of small secreted proteins that selectively recruit monocytes, neutrophils, and lymphocytes to sites of vascular injury, inflammation, and developing atherosclerosis. Chemokines induce chemotaxis through the activation of G-protein-coupled receptors, and the receptors that a given leukocyte expresses determines the chemokines to which it will respond. Monocyte chemoattractant protein 1 (MCP-1), acting through its receptor CCR2, appears to play an early and important role in the recruitment of monocytes to atherosclerotic lesions and in the formation of intimal hyperplasia after arterial injury. Acute thrombosis is an often fatal complication of atherosclerotic plaque rupture, and recent evidence suggests that MCP-1 contributes to thrombin generation and thrombus formation by generating tissue factor. Because of their critical roles in monocyte recruitment in vascular and nonvascular diseases, MCP-1 and CCR2 have become important therapeutic targets, and efforts are underway to develop potent and specific antagonists of these and related chemokines.

Abstract
OBJECTIVE Monocyte chemoattractant protein-1 (MCP-1) is reported to stimulate ischemia-induced arteriogenesis (collateral artery development) by recruiting monocytes and macrophages into areas of active arteriogenesis. To determine whether the MCP-1-mediated response occurs through its receptor, CC-chemokine receptor 2 (CCR2), we induced hindlimb ischemia in mice lacking the receptor for MCP-1 (CCR2 -/- ) and measured limb blood flow recovery, collateral artery development, and monocyte and macrophage recruitment. METHODS AND RESULTS Hindlimb ischemia was induced by excising the left femoral artery in CCR2 -/- and wild-type mice. Hindlimb blood flow recovery, as measured using laser Doppler perfusion imaging, was equivalent in both groups ( P = .78 for foot and P = 0.38 for calf). Collateral artery development, as measured by angiography at postoperative day 14 and 31, likewise did not differ between the 2 groups ( P = .46 and P = .67). Counts of monocytes and macrophages in calf and thigh muscle sections of mice sacrificed on postoperative day 7 revealed that although CCR2 -/- mice recruited 44% fewer monocytes and macrophages to areas of ischemia in the calf, they recruited similar numbers of monocytes and macrophages to areas of active arteriogenesis in the thigh. Intercellular adhesion molecule-1 and MCP-1 mRNA levels were higher in the thigh muscle of CCR2 -/- mice than in wild-type mice (5.5-fold and 42.3-fold induction operated to unoperated vs 2.6-fold and 6.1-fold induction operated to unoperated, respectively). CONCLUSIONS Blood flow recovery, arteriogenesis, and monocyte and macrophage recruitment to the thigh was normal in CCR2 -/- mice. However, monocyte and macrophage recruitment to the ischemic calf was diminished in CCR2 -/- mice. Our results show that MCP-1 signaling through CCR2 is not required for physiologic arteriogenesis in response to severe hindlimb ischemia. ICAM-1 upregulation may substitute for MCP-1 signaling through CCR2 in order to allow normal arteriogenesis in CCR2 -/- mice.

Abstract
BACKGROUND Transplantation of ex vivo expanded circulating endothelial progenitor cells (EPCs) from peripheral blood mononuclear cells improves the neovascularization after critical ischemia. However, the origin of the endothelial progenitor lineage and its characteristics have not yet been clearly defined. Therefore, we investigated whether the phenotype and functional capacity of EPCs to improve neovascularization depend on their monocytic origin. METHODS AND RESULTS Monocytic CD14+ cells were isolated from mononuclear cells and incubated on fibronectin-coated dishes in endothelial medium in the presence of vascular endothelial growth factor. After 4 days of cultivation, adherent cells deriving from CD14+ or CD14- mononuclear cells showed equal expression of endothelial marker proteins and capacity for clonal expansion as determined by measuring endothelial colony-forming units. In addition, transplanted EPCs (5x10(5) cells) deriving from CD14+ or CD14- cells were incorporated into vascular structures of nude mice after hind-limb ischemia and significantly improved neovascularization from 0.27+/-0.12 (no cells) to 0.66+/-0.12 and 0.65+/-0.17, respectively (P<0.001; laser Doppler-derived relative blood flow). In contrast, no functional improvement of neovascularization was detected when freshly isolated CD14+ mononuclear cells without ex vivo expansion were used (0.33+/-0.17). Moreover, macrophages or dendritic cells differentiated from isolated CD14+ cells were significantly less effective in improving neovascularization than EPCs cultivated from the same starting population (P<0.01). CONCLUSIONS These data demonstrate that EPCs can be generated from nonmonocytic CD14- peripheral blood mononuclear cells and exhibit a unique functional activity to improve neovascularization after hind-limb ischemia.
