Paracrine cross-talk between human adipose tissue-derived endothelial cells and perivascular cells accelerates the endothelialization of an electrospun ionomeric polyurethane scaffold.

Abstract
The ex vivo endothelialization of small diameter vascular prostheses can prolong their patency. Here, we demonstrate that heterotypic interactions between human adipose tissue-derived endothelial cells and perivascular cells can be exploited to accelerate the endothelialization of an electrospun ionomeric polyurethane scaffold. The scaffold was used to physically separate endothelial cells from perivascular cells to prevent their diffuse neo-intimal hyperplasia and spontaneous tubulogenesis, yet enable their paracrine cross-talk to accelerate the integration of the endothelial cells into a temporally stable endothelial lining of a continuous, elongated, and aligned morphology. Perivascular cells stimulated endothelial basement membrane protein production and suppressed their angiogenic and inflammatory activation to accelerate this biomimetic morphogenesis of the endothelium. These findings demonstrate the feasibility and underscore the value of exploiting heterotypic interactions between endothelial cells and perivascular cells for the fabrication of an endothelial lining intended for small diameter arterial reconstruction. STATEMENT OF SIGNIFICANCE: Adipose tissue is an abundant, accessible, and uniquely dispensable source of endothelial cells and perivascular cells for vascular tissue engineering. While their spontaneous self-assembly into microvascular networks is routinely exploited for the vascularization of engineered tissues, it threatens the temporal stability of an endothelial lining intended for small diameter arterial reconstruction. Here, we demonstrate that an electrospun polyurethane scaffold can be used to physically separate endothelial cells from perivascular cells to prevent their spontaneous capillary morphogenesis, yet enable their cross-talk to promote the formation of a stable endothelium. Our findings demonstrate the feasibility of engineering an endothelial lining from human adipose tissue, poising it for the rapid ex vivo endothelialization of small diameter vascular prostheses in an autologous, patient-specific manner.

Abstract
Cancer cells are embedded within the tissue and interact dynamically with its components during cancer progression. Understanding the contribution of cellular components within the tumor microenvironment is crucial for the success of therapeutic applications. Here, we reveal the presence of perivascular GFAP+/Plp1+ cells within the tumor microenvironment. Using in vivo inducible Cre/loxP mediated systems, we demonstrated that these cells derive from tissue-resident Schwann cells. Genetic ablation of endogenous Schwann cells slowed down tumor growth and angiogenesis. Schwann cell-specific depletion also induced a boost in the immune surveillance by increasing tumor-infiltrating anti-tumor lymphocytes, while reducing immune-suppressor cells. In humans, a retrospective in silico analysis of tumor biopsies revealed that increased expression of Schwann cell-related genes within melanoma was associated with improved survival. Collectively, our study suggests that Schwann cells regulate tumor progression, indicating that manipulation of Schwann cells may provide a valuable tool to improve cancer patients' outcomes.

Abstract
Aberrant angiogenesis is a hallmark of cancer and is critically associated with tumor progression. Perivascular cells are essential components of blood vessels, and the role of tumor perivascular cell-derived extracellular vesicles (TPC-EVs) in angiogenesis remains elusive. In the present study, using genetic mouse models and pharmacological inhibitors, we found that ablation of perivascular cells inhibited angiogenesis in allografted colorectal cancer tumors. Further studies demonstrated that TPC-EVs promoted the proliferation, migration, invasion, viability, and tube formation of HUVECs. They also facilitated vessel spouting in rat aortic rings and induced neovascularization in chick chorioallantoic membranes (CAMs). Silencing of Gas6 or blockade of the Axl pathway suppressed TPC-EV-induced angiogenesis in vitro and ex vivo. Moreover, inhibition of the Gas6/Axl signaling pathway impaired TPC-EV-mediated angiogenesis in vivo. Our findings present a deeper insight into the biological functions of TPCs and TPC-EVs in tumor angiogenesis and demonstrate that TPC-EV-derived Gas6 could be an attractive and innovative regulator of tumor angiogenesis.

Abstract
BACKGROUND Soluble proteins and extracellular vesicles (EVs) are crucial wound repair mediators in cell-based therapy. Previous studies reported that EVs of perivascular cells stimulated migration and proliferation of cell types involved in the dermatological wound healing process. However, these studies only show effects of EVs from perivascular cells (PVCs) for in vitro models. METHODS EVs were collected from 3D-cultured PVC (PVC-3D-EV) and compared with EVs from 2D-culture PVC (PVC-2D-EV) to investigate effects on wound contraction, angiogenesis, activation of myofibroblast, and collagen deposition. RESULTS PVC-3D-EV was significantly improved in terms of wound contraction compared with PVC-2D-EV and the control. Activation of myofibroblast and collagen deposition in a rat skin wound model was significantly stimulated by PVC-3D-EV. In addition, angiogenesis and vascular endothelial growth factor expression were also highly stimulated by PVC-3D-EV. These results suggest that PVC-3D-EV was regulated in granulation tissue formation, angiogenesis, and wound contraction in healing of a rat skin wound. These results indicate a pivotal role of PVC-3D-EV in wound healing through multiple mechanisms. CONCLUSIONS 3D-culture using a polystyrene scaffold is demonstrated to be a better system for providing better physiological conditions than the 2D-culture system, and EVs from 3D-cultured PVC could be a promising option for healing skin wound.

Abstract
BACKGROUND The purine adenosine triphosphate (ATP) plays a significant role in retinal blood flow regulation and recent evidence suggests that the vasoactive effect of the compound differs in vessels at different branching level. However, the cellular basis for the regulation of retinal blood flow mediated by ATP has only been scarcely studied. METHODS Perfused porcine hemiretinas (n = 60) were loaded with the calcium-sensitive fluorophore Oregon Green ex vivo. Spontaneous oscillations in fluorescence were studied in perivascular cells at five different vascular branching levels ranging from the main arteriole to the capillaries, before and after the addition of intra- and extravascular ATP alone or in the presence of a P2-purinergic receptor antagonist. RESULTS Intravascular ATP induced an overall significant (p < 0.01) constriction of (mean ± SD) -9.79 ± 13.40% and extravascular ATP an overall significant (p < 0.01) dilatation of (mean ± SD) 19.62 ± 13.47%. Spontaneous oscillations of fluorescence in perivascular cells were significantly more intense around third order arterioles than around vessels at both lower and higher branching levels (p < 0.05 for all comparisons). ATP increased intracellular fluorescence in perivascular cells of first and second order arterioles after extravascular application, and the increase correlated with the accompanying vasodilatation (p < 0.03). Blocking of P2-receptors reduced oscillating fluorescence in pre-capillary arterioles secondary to intravascular ATP (p = 0.03). CONCLUSIONS Spontaneous oscillations of calcium-sensitive fluorescence in perivascular retinal cells differ at different vascular branching levels. Extravascular ATP increases fluorescence in cells around the larger retinal arterioles exposed to the retinal surface. Future studies should investigate calcium signaling activity in perivascular retinal cells during interventions that simulate retinal pathology such as hypoxia.

Abstract
Surface topography drives the success of orthopedic and dental implants placed in bone, by directing the biology occurring at the tissue-implant interface. Over the last few decades, striking advancements have been made in the development of novel implant surfaces that enhance bone anchorage to their surfaces through contact osteogenesis: the combination of the two phenomena of recruitment and migration of mesenchymal progenitor cells to the implant surface, and their differentiation into bone-forming cells. While the latter is generally understood, the mechanisms and dynamics underlying the migration and recruitment of such progenitor cells into the wound site have garnered little attention. To address this deficit, we surgically inserted metallic implants with two different surface topographies into the skulls of mice, and then employed real-time spatiotemporal microscopic monitoring of the peri-implant tissue healing to track the ingress of cells. Our results show that nano-topographically complex, in comparison to relatively smooth, implant surfaces profoundly affect recruitment of both endothelial cells, which are essential for angiogenesis, and the mesenchymal progenitor cells that give rise to the reparative tissue stroma. The latter appear concomitantly in the wound site with endothelial cells, from the vascularized areas of the periosteum, and demonstrate a proliferative "bloom" that diminishes with time, although some of these cells differentiate into important stromal cells, pericytes and osteocytes, of the reparative wound. In separate experiments we show, using trajectory plots, that the directionality of migration for both endothelial and perivascular cells can be explained by implant surface dependent release of local cytokine gradients from platelets that would become activated on the implant surfaces during initial blood contact. These findings provide new biological insights into the earliest stages of wound healing, and have broad implications in the application of putative nano-topographically complex biomaterials in many tissue types.

Abstract
Purpose: Transplantation of autologous and/or allogeneic blood vessels is the most convenient treatment for vascular diseases. With regard to extensive need for blood vessels, developments in vascular tissue engineering are contributing greatly. In this study, our aim is to create intact small-diameter tubular vascular grafts cultivated in pulsatile flow bioreactor. Materials and Methods: CD146+ cell-based small-diameter vascular grafts were fabricated with ECM/glycosaminoglycans and polyurethane nanofibers. Characterization of the vascular graft was performed by SEM and WST-1. To mimic blood circulation in the bioreactor, human CD34+ cells cultured in megakaryocytes/platelets medium; then these cells were transferred inside of the vascular graft to mimic blood circulation. Cell differentiation was evaluated by flow cytometry and colony assay. Wright-Giemsa staining and polyploidy analysis were performed to show the differentiated cell population inside of the vascular graft. Anti-thrombogenic properties of the blood vessel were demonstrated by IF. Results: Polyurethane nanofibers provided a suitable environment for Human umbilical cord vein endothelial cells (HUVECs), and no significant cytotoxic effect was observed. Scanning electron microscopy (SEM) analysis of the tubular graft showed that under perfusion HUVECs, smooth muscle cells (SMCs) and fibroblasts formed layers that aligned on each other, respectively. The vascular graft was strong with a tensile strength of 0.70 MPa and elastic modulus of 0.007 GPa. When cultured in a bioreactor system, platelet adhesion to the vascular graft was remarkably low. Conclusion: In conclusion, this vascular graft may hold the potential to regenerate functional small-diameter vessels for cardiovascular tissue repair.

Abstract
Diabetes mellitus is a common heterogeneous metabolic disorder, characterized by
deposition of extracellular matrix, oxidative stress, and vascular dysfunction,
thereby leading to gradual loss of function in multiple organs. However, little
attention has been paid to gene expression changes in the lung under
hyperglycemic conditions. In this study, we found that diabetes inuced
histological changes in the lung of streptozotocin-induced diabetic mice. Global
gene expression profiling revealed a set of genes that are up- and
down-regulated in the lung of diabetic mice. Among these, expression of
Amigo2, Adrb2, and Zbtb16 were confirmed
at the transcript level to correlate significantly with hyperglycemia in the
lung. We further evaluated the effect of human umbilical cord-derived
perivascular stem cells (PVCs) on these gene expression in the lung of diabetic
mice. Our results show that administration of PVC-conditioned medium
significantly suppressed Amig2, Adrb2, and
Zbtb16 upregulation in these mice, suggesting that these
genes may be useful indicators of lung injury during hyperglycemia. Furthermore,
PVCs offer a promising alternative cell therapy for treating diabetic
complications via regulation of gene expression.

Abstract
Growing evidences suggest that peritubular capillaries pericytes are the main source of scar-forming myofibroblasts during chronic kidney disease (CKD), as well as early phases of acute kidney injury (AKI). In a swine model of sepsis and I/R (Ischemia Reperfusion) injury-induced AKI we demonstrated that renal pericytes are able to transdifferentiate toward α-SMA+ myofibroblasts leading to interstitial fibrosis. Even if precise pericytes identification requires transmission electron microscopy and the co-immunostaining of several markers (i.e., Gli, NG2 chondroitin sulphate proteoglycan, CD146, desmin or CD73) and emerging new markers (CD248 or TEM1, endosialin), previous studies suggested that PDGFR-β could be used as marker for renal pericytes characterization. Recently, double immunofluorescence staining of PDGFR-β and α-SMA was performed to identify the damage activated pericytes (PDGFR-β+/α-SMA+ cells) in the early phase of fibrosis development. Our data highlighted the crucial role of renal pericytes in the physiopathology of sepsis and I/R associated AKI. In this protocol, we describe the procedure for double immunofluorescence staining of PDGFR-β and α-SMA in swine Formalin-Fixed Paraffin-Embedded (FFPE) kidney biopsies and the method for image analysis and quantification.

Abstract
The increasing application of approaches that allow tracing of individual cells over time, together with transcriptomic and epigenomic analyses is changing the way resident stromal stem cells (mesenchymal stem cells) are viewed. Rather than being a defined, homogeneous cell population as described following in vitro expansion, in vivo, these cells are highly programmed according to their resident tissue location. This programming is evidenced by different epigenetic landscapes and gene transcription signatures in cells before any in vitro expansion. This has potentially profound implications for the heterotypic use of these cells in therapeutic tissue engineering applications.

Abstract
BACKGROUND Perivascular cells (PVC) and their "progeny," mesenchymal stromal cells (MSC), have high therapeutic potential for ischemic diseases. While hypoxia can increase their angiogenic properties, the other aspect of ischemic conditions-glucose shortage-is deleterious for MSC and limits their therapeutic applicability. Regenerative cells in developing vascular tissues, however, can adapt to varying glucose environment and react in a tissue-protective manner. Placental development and fetal insulin production generate different glucose fluxes in early and late extraembryonic tissues. We hypothesized that FTM HUCPVC, which are isolated from a developing vascular tissue with varying glucose availability react to low-glucose conditions in a pro-angiogenic manner in vitro. METHODS Xeno-free (Human Platelet Lysate 2.5%) expanded FTM (n = 3) and term (n = 3) HUCPVC lines were cultured in low (2 mM) and regular (4 mM) glucose conditions. After 72 h, the expression (Next Generation Sequencing) and secretion (Proteome Profiler) of angiogenic factors and the functional angiogenic effect (rat aortic ring assay and Matrigel™ plug) of the conditioned media were quantified and statistically compared between all cultures. RESULTS Low-glucose conditions had a significant post-transcriptional inductive effect on FTM HUCPVC angiogenic factor secretion, resulting in significantly higher VEGFc and Endothelin 1 release in 3 days compared to term counterparts. Conditioned media from low-glucose FTM HUCPVC cultures had a significantly higher endothelial network enhancing effect compared to all other experimental groups both in vitro aortic ring assay and in subcutan Matrigel™ plugs. Endothelin 1 depletion of the low-glucose FTM HUCPVC conditioned media significantly diminished its angiogenic effect CONCLUSIONS: FTM HUCPVC isolated from an early extraembryonic tissue show significant pro-angiogenic paracrine reaction in low-glucose conditions at least in part through the excess release of Endothelin 1. This can be a substantial advantage in cell therapy applications for ischemic injuries.

Abstract
In amyotrophic lateral sclerosis (ALS), motor neurons die selectively. Therefore, initial symptoms that include fasciculation, spasticity, muscle atrophy, and weakness emerge following axons retraction and consequent muscles' denervation. Patients lose the ability to talk and swallow and rely on parenteral nutrition and assisted ventilation to survive. The degeneration caused by ALS is progressive and irreversible. In addition to the autonomous mechanism of neuronal cell death, non-autonomous mechanisms have been proved to be toxic for motor neurons, such as the activation of astrocytes and microglia. Among the cells being studied to unveil these toxic mechanisms are pericytes, cells that help keep the integrity of the blood-brain barrier and blood-spinal cord barrier. In this chapter, we aim to discuss the role of pericytes in ALS.

Abstract
The pericytes of the testis are part of the omnipresent population of pericytes in the vertebrate body and are the only true pluripotent adult stem cells able to produce structures typical for the tree primitive germ layers: ectoderm, mesoderm, and endoderm. They originate very early in the embryogenesis from the pluripotent epiblast. The pericytes become disseminated through the whole vertebrate organism by the growing and differentiating blood vessels where they remain in specialized periendothelial vascular niches as resting pluripotent adult stem cells for tissue generation, maintenance, repair, and regeneration. The pericytes are also the ancestors of the perivascular multipotent stromal cells (MSCs). The variable appearance of the pericytes and their progeny reflects the plasticity under the influence of their own epigenetic and the local environmental factors of the host organ. In the testis the pericytes are the ancestors of the neuroendocrine Leydig cells. After activation the pericytes start to proliferate, migrate, and build transit-amplifying cells that transdifferentiate into multipotent stromal cells. These represent progenitors for a number of different cell types in an organ. Finally, it becomes evident that the pericytes are a brilliant achievement of the biological nature aiming to supply every organ with an omnipresent population of pluripotent adult stem cells. Their fascinating features are prerequisites for future therapy concepts supporting cell systems of organs.

Abstract
Bone marrow environments are composed of multiple cell types, most of which are thought to be derived from mesenchymal stem cells. In mouse bone marrow, stromal cells with CD45- Tie2- CD90- CD51+ CD105+ phenotype, Nestin-GFP+, CXCL12-abundant reticular (CAR) cells, PDGFRα+ Sca-1+ or CD51+ PDGFRα+, and Prx-1-derived CD45- Ter119- PDGFRα+ Sca-1+ populations select for MSC activity. There is evidence that these stromal cell populations display some significant overlap with each other and comprise important cellular constituents of the hematopoietic stem cell niche. Moreover, these mesenchymal cell populations share characteristics in their location as they all are found around bone marrow vessels (can be called "pericytes"). In this chapter, with reviewing the recent literatures, how the pericytes relate to physiological and pathological hematopoiesis is argued.

Abstract
Fibrosis following injury leads to aberrant regeneration and incomplete functional recovery of skeletal muscle, but the lack of detailed knowledge about the cellular and molecular mechanisms involved hampers the design of effective treatments. Using state-of-the-art technologies, Murray et al. (2017) found that perivascular PDGFRβ-expressing cells generate fibrotic cells in the skeletal muscle. Strikingly, genetic deletion of αv integrins from perivascular PDGFRβ-expressing cells significantly inhibited skeletal muscle fibrosis without affecting muscle vascularization or regeneration. In addition, the authors showed that a small molecule inhibitor of αv integrins, CWHM 12, attenuates skeletal muscle fibrosis. From a drug-development perspective, this study identifies a new cellular and molecular target to treat skeletal muscle fibrosis.

Abstract
Due to the increasing age of our society and a rise in engagement of young people in extreme and/or competitive sports, both tendinopathies and tendon ruptures present a clinical and financial challenge. Tendon has limited natural healing capacity and often responds poorly to treatments, hence it requires prolonged rehabilitation in most cases. Till today, none of the therapeutic options has provided successful long-term solutions, meaning that repaired tendons do not recover their complete strength and functionality. Our understanding of tendon biology and healing increases only slowly and the development of new treatment options is insufficient. In this review, following discussion on tendon structure, healing and the clinical relevance of tendon injury, we aim to elucidate the role of stem cells in tendon healing and discuss new possibilities to enhance stem cell treatment of injured tendon. To date, studies mainly apply stem cells, often in combination with scaffolds or growth factors, to surgically created tendon defects. Deeper understanding of how stem cells and vasculature in the healing tendon react to growth factors, common drugs used to treat injured tendons and promising cellular boosters could help to develop new and more efficient ways to manage tendon injuries.

Abstract
Very small embryonic-like stem cells (VSELs) are major pluripotent stem cells defined as cells of small size being Lineage- negative, CD133-positive, and CD45-negative. We previously described that human bone marrow VSELs were able to differentiate into endothelial cells and promoted post-ischemic revascularization in mice with surgically induced critical limb ischemia. In the present work, we isolated bone marrow VSELs from patients with critical limb ischemia and studied their ability to support endothelial progenitor cells therapeutic capacity and revascularization potential. Sorted bone marrow VSELs cultured in angiogenic media were co-injected with endothelial progenitor cells and have been show to trigger post-ischemic revascularization in immunodeficient mice, and support vessel formation in vivo in Matrigel implants better than human bone marrow mesenchymal stem cells. In conclusion, VSELs are a potential new source of therapeutic cells that may give rise to cells of the endothelial and perivascular lineage in humans. VSELs are the first real vasculogenic stem cells able to differentiate in endothelial and perivascular lineage in human adult described from now. Thus, because VSELs presence have been proposed in adult tissues, we think that VSELs are CD45 negative stem cells able to give rise to vascular regeneration in human tissues and vessels.

Abstract
Background Due to limitations of current angiogenesis assays, we aimed to develop a novel application of the rat aortic ring assay to assess the angiogenic potential of mesenchymal stromal cells (MSCs). First-trimester human umbilical cord-derived perivascular cells (FTM HUCPVCs) have multipotent characteristics and previously demonstrated angiogenic potential. We compared the effect of this young source of MSCs and adult bone marrow stromal cells (BMSCs) on ex vivo aortic endothelial network formation. Methods Thoracic segments of adult rat aortas were isolated, sectioned and embedded into Matrigel™. Fluorophore-labeled FTM HUCPVC lines and BMSCs (N = 3) were cocultured with developing endothelial networks (day 0). MSC integration, tube formation and endothelial network growth were monitored daily using phase-contrast and fluorescence microscopy. Quantification of endothelial networks was performed using ImageJ network analysis software on day 5 of coculture. Results FTM HUCPVCs from two umbilical cord samples migrated toward and integrated with developing aortic ring tubular networks while displaying elongated morphologies (day 1). In contrast, BMSCs did not show targeted migration and maintained spherical morphologies with limited physical interactions. Within 1 week of coculture, FTM HUCPVC lines contributed to significantly greater radial network growth and network loop formation when compared to BMSCs and untreated networks. Conclusions We have developed a novel potency assay to assess the angiogenic potential of cell therapy candidates. Favorable properties of FTM HUCPVCs over BMSCs that we observed with this assay and which merit further study include chemotaxis, affinity for developing vasculature, and physical supportive interactions contributing to the development of endothelial networks.

Abstract
Angiogenesis defines the process of formation of new vascular structures form existing blood vessels, involved during development, repair processes like wound healing but also linked to pathological changes. During angiogenic processes, endothelial cells build a vascular network and recruit perivascular cells to form mature, stable vessels. Endothelial cells and perivascular cells secret and assemble a vascular basement membrane and interact via close cell-cell contacts. To mimic these processes in vitro we have developed a versatile three-dimensional culture system where perivascular cells (PVC) are co-cultured with human umbilical cord vascular endothelial cells (HUVEC) in a collagen type I gel. This co-culture system can be used to determine biochemical and cellular processes during neoangiogenic events with a wide range of analyses options.

Abstract
Understanding the crosstalk mechanisms between perivascular cells (PVCs) and cancer cells might be beneficial in preventing cancer development and metastasis. In this study, we investigated the paracrine influence of PVCs derived from human umbilical cords on the proliferation of lung adenocarcinoma epithelial cells (A549) and erythroleukemia cells (TF-1α and K562) in vitro using Transwell® co-culture systems. PVCs promoted the proliferation of A549 cells without inducing morphological changes, but had no effect on the proliferation of TF-1α and K562 cells. To identify the factors secreted from PVCs, conditioned media harvested from PVC cultures were analyzed by antibody arrays. We identified a set of cytokines, including persephin (PSPN), a neurotrophic factor, and a key regulator of oral squamous cell carcinoma progression. Supplementation with PSPN significantly increased the proliferation of A549 cells. These results suggested that PVCs produced a differential effect on the proliferation of cancer cells in a cell-type dependent manner. Further, secretome analyses of PVCs and the elucidation of the molecular mechanisms could facilitate the discovery of therapeutic target(s) for lung cancer.

Abstract
The recent development of tissue engineering provides exciting new perspectives for the replacement of failing organs and the repair of damaged tissues. Perivascular cells, including vascular smooth muscle cells, pericytes and other tissue specific populations residing around blood vessels, have been isolated from many organs and are known to participate to the in situ repair process and angiogenesis. Their potential has been harnessed for cell therapy of numerous pathologies; however, in this Review we will discuss the potential of perivascular cells in the development of tissue engineering solutions for healthcare. We will examine their application in the engineering of vascular grafts, cardiac patches and bone substitutes as well as other tissue engineering applications and we will focus on their extensive use in the vascularization of engineered constructs. Additionally, we will discuss the emerging potential of human pericytes for the development of efficient, vascularized and non-immunogenic engineered constructs.

Abstract
Arf encodes an important tumor suppressor, p19(Arf), which also plays a critical role to control hyperplasia in the primary vitreous during mouse eye development. In the absence of Arf, mice are born blind and display a phenotype closely mimicking severe forms of the human eye disease, persistent hyperplastic primary vitreous (PHPV). In this report, we characterize p19(Arf) expression in perivascular cells that normally populate the primary vitreous and express the Arf promoter. Using a new ex vivo model, we show that these cells respond to exogenous Tgfβ, despite being isolated at a time when Tgfβ has already turned on the Arf promoter. Treatment of the cells with PDGF-B ligand doubles the population of cells in S-phase and ectopic expression of Arf blunts that effect. We show this effect is mediated through Pdgfrβ as expression of Arf represses expression of Pdgfrβ mRNA and protein to approximately 60%. p53 is not required for Arf-dependent blockade of PDGF-B driven proliferation and repression of Pdgfrβ protein as ectopic expression of Arf is still able to inhibit the 2-fold increase in the S-phase fraction of cells upon treatment with PDGF-B. Finally, induction of mature miR-34a, a microRNA previously identified to be regulated by p19(Arf) does not depend on p53 while the expression of the primary transcript does require p53. These data corroborate that, as in vivo, p19(Arf) functions to inhibit PDGF-B driven proliferation ex vivo.

Abstract
Perivascular cells are known to be ancestors of mesenchymal stem cells (MSCs) and can be obtained from heart, skin, bone marrow, eye, placenta and umbilical cord (UC). However detailed characterization of perivascular cells around the human UC vein and comparative analysis of them with MSCs haven't been done yet. In this study, our aim is to isolate perivascular cells from human UC vein and characterize them versus UC blood MSCs (UCB-MSCs). For this purpose, perivascular cells around the UC vein were isolated enzymatically and then purified with magnetic activated cell sorting (MACS) method using CD146 Microbead Kit respectively. MSCs were isolated from UCB by Ficoll density gradient solution. Perivascular cells and UCB-MSCs were characterized by osteogenic and adipogenic differentiation procedures, flow cytometric analysis [CD146, CD105, CD31, CD34, CD45 and alpha-smooth muscle actin (α-SMA)], and immunofluorescent staining (MAP1B and Tenascin C). Alizarin red and Oil red O staining results showed that perivascular cells and MSCs had osteogenic and adipogenic differentiation capacity. However, osteogenic differentiation capacity of perivascular cells were found to be less than UCB-MSCs. According to flow cytometric analysis, CD146 expression of perivascular cells were appeared to be 4.8-fold higher than UCB-MSCs. Expression of α-SMA, MAP1B and Tenascin-C from perivascular cells was determined by flow cytometry analysis and immunfluorescent staining. The results appear to support the fact that perivascular cells are the ancestors of MSCs in vascular area. They may be used as alternative cells to MSCs in the field of vascular tissue engineering.

Abstract
The cellular basis for the regulation of retinal blood flow is unknown, but recently a new type of perivascular cell (PVC) with pericyte characteristics was identified in the retinal arterial vascular wall located immediately external to the vascular smooth muscle cells. A possible involvement of this cell type in the regulation of retinal vascular tone might be elucidated by studying differences in the response after the addition of compounds stimulating respectively relaxation and contraction. The effects of PGE2 and PGF2α on vascular tone and calcium activity in PVCs in porcine retinal arterioles were studied in a confocal myograph after the addition of the ryanodine receptor blocker ryanodine, the L-type Ca(2+) channel blocker nifedipine, the non-specific cation channel blocker LOE908, the sarcoplasmic reticulum Ca(2+)-ATPase (SERCA) blocker CPA, and the inositol triphosphate receptor (IP3R) and transient receptor potential (TRP) ion channel blocker 2-APB. The Ca(2+) channel blockers nifedipine and LOE908 induced significant relaxation of retinal arterioles. After the addition of both PGE2 and PGF2α calcium activity in the PVCs was significantly reduced by both the SERCA inhibitor CPA and the IP3R antagonist 2-APB, but the changes in calcium activity were unrelated to the changes in tone induced by PGE2 and PGF2α. Changes in the tone of porcine retinal arterioles in vitro induced by PGE2 and PGF2α involve other factors than calcium activity in the perivascular cells.
