[PMID: 38043894 DOI: 10.1016/j.envres.2023.117795] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/01/2022] [Revised: 10/26/2023] [Accepted: 11/24/2023] [Indexed: 12/05/2023]
Abstract
The increasing burden of cardiovascular disease (CVD) remains responsible for morbidity and mortality worldwide; their effective diagnostic or treatment methods are of great interest to researchers. The use of NPs and nanocarriers in cardiology has drawn much interest. The present comprehensive review provides deep insights into the use of current and innovative approaches in CVD diagnostics to offer practical ways to utilize nanotechnological interventions and the critical elements in the CVD diagnosis, associated risk factors, and management strategies of patients with chronic CVDs. We proposed a decision tree-based solution by discussing the emerging applications of NPs for the higher number of rules to increase efficiency in treating CVDs. This review-based study explores the screening methods, tests, and toxicity to provide a unique way of creating a multi-parametric feature that includes cutting-edge techniques for identifying cardiovascular problems and their treatments. We discussed the benefits and drawbacks of various NPs in the context of cost, space, time and complexity that have been previously suggested in the literature for the diagnosis of CVDs risk factors. Also, we highlighted the advances in using NPs for targeted and improved drug delivery and discussed the evolution toward the nano-cardiovascular potential for medical science. Finally, we also examined the mixed-based diagnostic approaches crucial for treating cardiovascular disorders, broad applications and the potential future applications of nanotechnology in medical sciences.

Redox-responsive polyurethane-polyurea nanoparticles targeting to aortic endothelium and atherosclerosis. iScience 2022; 25:105390. [PMID: 36345337 PMCID: PMC9636043 DOI: 10.1016/j.isci.2022.105390] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/14/2022] [Revised: 07/23/2022] [Accepted: 10/14/2022] [Indexed: 11/09/2022] Open
Abstract
Aortic endothelial cell dysfunction is an early trigger of atherosclerosis, the major cause of the cardiovascular disease (CVD). Nanomedicines targeting vascular endothelium and lesions hold great promise as therapeutic solutions to vascular disorders. This study investigates the vascular delivery efficacy of polyurethane-polyurea nanocapsules (Puua-NCs) with pH-synchronized shell cationization and redox-triggered release. Fluorescent lipophilic dye DiI was encapsulated into Puua-NCs of variable sizes and concentrations. In vitro cellular uptake studies with human aortic endothelial cells showed that these Puua-NCs were taken up by cells in a dose-dependent manner. In apolipoprotein E-deficient mice fed a Western diet, a model of atherosclerosis, circulating Puua-NCs were stable and accumulated in aortic endothelium and lesions within 24 hours after intravenous administration. Treatment with thiol-reducing and oxidizing reagents disrupted the disulfide bonds on the surface of internalized NCs, triggering disassembly and intracellular cargo release. Ultimately, Puua-NCs are a potential redox-controllable cardiovascular drug delivery system.

Abstract
Atherosclerosis represents one of the major causes of death globally. The high mortality rates and limitations of current therapeutic modalities have urged researchers to explore potential alternative therapies. The clustered regularly interspaced short palindromic repeats-associated protein 9 (CRISPR/Cas9) system is commonly deployed for investigating the genetic aspects of Atherosclerosis. Besides, advances in CRISPR/Cas system has led to extensive options for researchers to study the pathogenesis of this disease. The recent discovery of Cas9 variants, such as dCas9, Cas9n, and xCas9 have been established for various applications, including single base editing, regulation of gene expression, live-cell imaging, epigenetic modification, and genome landscaping. Meanwhile, other Cas proteins, such as Cas12 and Cas13, are gaining popularity for their applications in nucleic acid detection and single-base DNA/RNA modifications. To date, many studies have utilized the CRISPR/Cas9 system to generate disease models of atherosclerosis and identify potential molecular targets that are associated with atherosclerosis. These studies provided proof-of-concept evidence which have established the feasibility of implementing the CRISPR/Cas system in correcting disease-causing alleles. The CRISPR/Cas system holds great potential to be developed as a targeted treatment for patients who are suffering from atherosclerosis. This review highlights the advances in CRISPR/Cas systems and their applications in establishing pathogenetic and therapeutic role of specific genes in atherosclerosis.

Abstract
The endothelium is a crucial regulator of vascular homeostasis by controlling barrier integrity as well acting as an important signal transducer, thereby illustrating that endothelial cells are not inert cells. In the context of atherosclerosis, this barrier function is impaired and endothelial cells become activated, resulting in the upregulation of adhesion molecules, secretion of cytokines and chemokines and internalization of integrins. Finally, this leads to increased vessel permeability, thereby facilitating leukocyte extravasation as well as fostering a pro-inflammatory environment. Additionally, activated endothelial cells can form migrating tip cells and proliferative stalk cells, resulting in the formation of new blood vessels. Emerging evidence has accumulated indicating that cellular metabolism is crucial in fueling these pro-atherosclerotic processes, including neovascularization and inflammation, thereby contributing to plaque progression and altering plaque stability. Therefore, further research is necessary to unravel the complex mechanisms underlying endothelial cell metabolic changes, and exploit this knowledge for finding and developing potential future therapeutic strategies. In this review we discuss the metabolic alterations endothelial cells undergo in the context of inflammation and atherosclerosis and how this relates to changes in endothelial functioning. Finally, we will describe several metabolic targets that are currently being used for therapeutic interventions.

Abstract
Cardiovascular diseases (CVDs) have become a serious threat to human life and health. Though many drugs acting via different mechanism of action are available in the market as conventional formulations for the treatment of CVDs, they are still far from satisfactory due to poor water solubility, low biological efficacy, non-targeting, and drug resistance. Nano-drug delivery systems (NDDSs) provide a new drug delivery method for the treatment of CVDs with the development of nanotechnology, demonstrating great advantages in solving the above problems. Nevertheless, there are some problems about NDDSs need to be addressed, such as cytotoxicity. In this review, the types and targeting strategies of NDDSs were summarized, and the new research progress in the diagnosis and therapy of CVDs in recent years was reviewed. Future prospective for nano-carriers in drug delivery for CVDs includes gene therapy, in order to provide more ideas for the improvement of cardiovascular drugs. In addition, its safety was also discussed in the review.

Abstract
Xenogeneic biomaterials contain biologically relevant extracellular matrix (ECM) composition and organization, making them potentially ideal surgical grafts and tissue engineering scaffolds. Defining the effect of ECM niche (e.g., basement membrane vs. non-basement membrane) on repopulating cell phenotype and function has important implications for use of xenogeneic biomaterials, particularly in vascular applications. We aim to understand how serous (i.e., basement membrane) versus fibrous (i.e., non-basement membrane) ECM niche of antigen-removed bovine pericardium (AR-BP) scaffolds influence human aortic endothelial cell (hAEC) adhesion, growth, phenotype, inflammatory response and laminin production. At low and moderate seeding densities hAEC proliferation was significantly increased on the serous side. Similarly, ECM niche modulated cellular morphology, with serous side seeding resulting in a more rounded aspect ratio and intact endothelial layer formation. At moderate seeding densities, hAEC production of human laminin was enhanced following serous seeding. Finally, inflammatory marker and pro-inflammatory cytokine expression decreased following long-term cell growth regardless of seeding side. This work demonstrates that at low and moderate seeding densities AR-BP sidedness significantly impacts endothelial cell growth, morphology, human laminin production, and inflammatory state. These findings suggest that ECM niche has a role in modulating response of repopulating recipient cells toward AR-BP scaffolds for vascular applications.

Abstract
Human induced pluripotent stem cells (iPSCs) can be derived from various types of somatic cells by transient overexpression of 4 Yamanaka factors (OCT4, SOX2, C-MYC, and KLF4). Patient-specific iPSC derivatives (e.g., neuronal, cardiac, hepatic, muscular, and endothelial cells [ECs]) hold great promise in drug discovery and regenerative medicine. In this study, we aimed to evaluate whether the cellular origin can affect the differentiation, in vivo behavior, and single-cell gene expression signatures of human iPSC-derived ECs. We derived human iPSCs from 3 types of somatic cells of the same individuals: fibroblasts (FB-iPSCs), ECs (EC-iPSCs), and cardiac progenitor cells (CPC-iPSCs). We then differentiated them into ECs by sequential administration of Activin, BMP4, bFGF, and VEGF. EC-iPSCs at early passage (10 < P < 20) showed higher EC differentiation propensity and gene expression of EC-specific markers (PECAM1 and NOS3) than FB-iPSCs and CPC-iPSCs. In vivo transplanted EC-iPSC-ECs were recovered with a higher percentage of CD31+ population and expressed higher EC-specific gene expression markers (PECAM1, KDR, and ICAM) as revealed by microfluidic single-cell quantitative PCR (qPCR). In vitro EC-iPSC-ECs maintained a higher CD31+ population than FB-iPSC-ECs and CPC-iPSC-ECs with long-term culturing and passaging. These results indicate that cellular origin may influence lineage differentiation propensity of human iPSCs; hence, the somatic memory carried by early passage iPSCs should be carefully considered before clinical translation.

Abstract
ZnS nanoarchitectures have been intensively investigated recently because of their applications in optoelectronics and adsorption capacity. The potential hazard of ZnS nanoarchitectures is not well known. In this study, we investigated the toxicity of ZnS nanoarchitectures on vascular endothelial cell (VEC) in vitro and in vivo. The results showed that ZnS could inhibit human umbilical vein endothelial cell (HUVEC) proliferation at 50 and 200 μg/mL. Endothelial nitric oxide synthase (eNOS) activity, nitric oxide (NO), and reactive oxygen species productions were increased, which was companied with the decrease in caveolin-1 level. The endothelium of the aortic root was damaged and the NO levels in serum were elevated in the mice treated with 5 or 10 mg/kg ZnS for 3 and 6 days, but the body could repair the damage. The data suggested that the high concentration of ZnS could induce dysfunction of VECs through decreasing caveolin-1 and elevation of the eNOS activity and thus present toxicity.

Nano-Mg(OH)2-induced proliferation inhibition and dysfunction of human umbilical vein vascular endothelial cells through caveolin-1-mediated endocytosis. Cell Biol Toxicol 2015; 31:15-27.

Abstract
Nano-Mg(OH)2 is efficiently used in pollutant adsorption and removal due to its high adsorption capability, low-cost, and recyclability. A recent research from our group showed that Mg(OH)2 nanoflakes are not evidently internalized by cancer cells and are not cytotoxic. But the biocompatibility and potential toxicity of nano-Mg(OH)2 in a normal biological system are largely unclear. Nanoparticles could affect the function of endothelial cells, and endothelial dysfunction represents an early sign of lesion within the vasculature. Here, we applied the human umbilical vein vascular endothelial cells (HUVECs) as an in vitro model of the endothelium to study the cytotoxicity of nano-Mg(OH)2. Our results showed that nano-Mg(OH)2 at 200 μg/ml impaired proliferation and induced dysfunction of HUVECs, but did not result in cell necrosis and apoptosis. Transmission electron microscopy images and immunofluorescence results showed that the nano-Mg(OH)2 could enter HUVECs through caveolin-1-mediated endocytosis. Nano-Mg(OH)2 at high concentrations decreased the level of caveolin-1 and increased the activity of endothelial nitric oxide synthase (eNOS), thus leading to the production of excess nitric oxide (NO). In this work, we provide the cell damage concentrations of nano-Mg(OH)2 nanoparticles, and we propose a mechanism of injury induced by nano-Mg(OH)2 in HUVECs.

Abstract
BACKGROUND AIMS Numerous protocols for the isolation of bovine aortic endothelial cells have been described in the previous literature. However, these protocols prevent researchers from obtaining the pure population of endothelial cells. Thus, this study aimed to develop a new and economical method for the isolation of pure endothelial cells by introducing a new strategy to the enzymatic digestion method proposed by previous researchers. METHODS With the use of this method, the lumen of a bovine aorta was filled with wash medium and the outer surface of the sample was washed with alcohol for 30 seconds. Under a laminar flow hood, the inner surface of the sample was covered with filter paper. Collagenase type II was dripped onto the filter paper as a digestion enzyme. The digestion fluid was seeded in T25 flasks and fed with complete medium every 3 days. RESULTS The isolated cells were characterized by markers such as CD31, von Willebrand factor, 1,1'-dioctadecyl-1,3,3,3',3'-tetramethylindocarbocyanine perchlorate acetylated low-density lipoprotein and angiogenesis behavior. The purity of endothelial cells was detected by flow cytometry to be of nearly 90% purity; these results were confirmed by immunostaining. Moreover, endothelial cells formed blood vessel-like tubes in a three-dimensional environment, which is specific dynamic behavior for endothelial cells. CONCLUSIONS The new strategy presented in the current report enables isolation of a highly pure population of endothelial cells that can survive long-term culture without inducing an overgrowth of fibroblast cells.

Abstract
Current in vitro methods to assess nanomaterial cytotoxicity involve various assays to monitor specific cellular dysfunction, such as metabolic imbalance or inflammation. Although high throughput, fast, and animal-free, these in vitro methods suffer from unreliability and lack of relevance to in vivo situations. New approaches, especially with the potential to reliably relate to in vivo studies directly, are in critical need. This work introduces a new approach, single cell mechanics, derived from atomic force microscopy-based single cell compression. The single cell based approach is intrinsically advantageous in terms of being able to directly correlate to in vivo investigations. Its reliability and potential to measure cytotoxicity is evaluated using known systems: zinc oxide (ZnO) and silicon dioxide (SiO2) nanoparticles (NP) on human aortic endothelial cells (HAECs). This investigation clearly indicates the reliability of single cell compression. For example, ZnO NPs cause significant changes in force vs relative deformation profiles, whereas SiO2 NPs do not. New insights into NPs-cell interactions pertaining to cytotoxicity are also revealed from this single cell mechanics approach, in addition to a qualitative cytotoxicity conclusion. The advantages and disadvantages of this approach are also compared with conventional cytotoxicity assays.

Abstract
One major obstacle for successful application of nanoparticles in medicine is its potential nanotoxicity on the environment and human health. In this study, we evaluated the cytotoxicity effect of dimercaptosuccinic acid-coated iron oxide (DMSA-Fe2O3) using cultured human aortic endothelial cells (HAECs). Our results showed that DMSA-Fe2O3 in the culture medium could be absorbed into HAECs, and dispersed in the cytoplasm. The cytotoxicity effect of DMSA-Fe2O3 on HAECs was dose-dependent, and the concentrations no more than 0.02 mg/ml had little toxic effect which were revealed by tetrazolium dye assay. Meanwhile, the cell injury biomarker, lactate dehydrogenase, was not significantly higher than that from control cells (without DMSA-Fe2O3). However, the endocrine function for endothelin-1 and prostacyclin I-2, as well as the urea transporter function, was altered even without obvious evidence of cell injury in this context. We also showed by real-time PCR analysis that DMSA-Fe2O3 exposure resulted in differential effects on the expressions of pro- and anti-apoptosis genes of HAECs. Meanwhile, it was noted that DMSA-Fe2O3 exposure could activate the expression of genes related to oxidative stress and adhesion molecules, which suggested that inflammatory response might be evoked. Moreover, we demonstrated by in vitro endothelial tube formation that even a small amount of DMSA-Fe2O3 (0.01 and 0.02 mg/ml) could inhibit angiogenesis by the HAECs. Altogether, these results indicate that DMSA-Fe2O3 have some cytotoxicity that may cause side effects on normal endothelial cells.

Abstract
Manufactured nanoparticles are currently used for many fields. However, their potential toxicity provides a growing concern for human health. In our previous study, we prepared novel magnetic nanoparticles (MNPs), which could effectively remove heavy metal ions and cationic dyes from aqueous solution. To understand its biocompatibility, we investigated the effect of the nanoparticles on the function of vascular endothelial cells. The results showed that the nanoparticles were taken up by human umbilical vein endothelial cells (HUVECs) and could inhibit cell proliferation at 400 μg/ml. An increase in nitric oxide (NO) production and endothelial nitric oxide synthase (eNOS) activity were induced, which companied with the decrease in caveolin-1 level. The endothelium in the aortic root was damaged and the NO level in serum was elevated after treated mice with 20mg/kg nanoparticles for 3 days, but it was integrated after treated with 5mg/kg nanoparticles. Meanwhile, an increase in eNOS activity and decrease in caveolin-1 level were induced in the endothelium. The data suggested that the low concentration of nanoparticles could not affect the function and viability of VECs. The high concentration of nanoparticles could inhibit VEC proliferation through elevation of the eNOS activity and NO production and thus present toxicity.

Abstract
Background The non-destructive assessment and characterization of tridimensional (3D) cell and tissue constructs in bioreactors represents a challenge in tissue engineering. Medical imaging modalities, which can provide information on the structure and function of internal organs and tissues in living organisms, have the potential of allowing repetitive monitoring of these 3D cultures in vitro. Positron emission tomography (PET) is the most sensitive non-invasive imaging modality, capable of measuring picomolar amounts of radiolabeled molecules. However, since PET imaging protocols have been designed almost exclusively for in vivo investigations, suitable methods must be devised to enable imaging of cells or tissue substitutes. As a prior step to imaging 3D cultures, cell radiotracer uptake conditions must first be optimized. Methods In this study, human umbilical vein endothelial cells (HUVEC) and human fibroblasts were cultured at different densities and PET was used to non-destructively monitor their glycolytic activity by measuring 18F-fluorodeoxyglucose (18FDG) uptake. Various cell preconditioning protocols were investigated by adjusting the following parameters to optimize 18FDG uptake: glucose starvation, insulin stimulation, glucose concentration, 18FDG incubation time, cell density and radiotracer efflux prevention. Results The conditions yielding optimal 18FDG uptake, and hence best detection sensitivity by PET, were as follows: 2-hour cell preconditioning by glucose deprivation with 1-hour insulin stimulation, followed by 1-hour 18FDG incubation and 15-minute stabilization in standard culture medium, prior to rinsing and PET scanning. Conclusions A step-wise dependence of 18FDG uptake on glucose concentration was found, but a linear correlation between PET signal and cell density was observed. Detection thresholds of 36 ± 7 and 21 ± 4 cells were estimated for endothelial cells and fibroblasts, respectively.

Abstract
BACKGROUND Nonalcoholic fatty liver disease (NAFLD) is strongly associated to oxidative stress, metabolic syndrome, and cardiovascular risk. Hepatocytes overloaded with fatty acids (FA) could generate substances that interfere with endothelial function, providing a potential explanation for this association. We have investigated the response of cultured human hepatoblastoma cells (Hep-G2) that were exposed to FA by measuring markers of oxidative stress and thrombosis and expression of the insulin receptor. METHODS Hep-G2 cells were conditioned with a mixture of FA with or without N-acetyl-L-cysteine (NAC), glutathione (GSH), or adiponectin (ADN). After 7 days, we measured intracellular GSH (iGSH), nitric oxide (NO), malondialdehyde (MDA), and tissue plasminogen inhibitor-1 (PAI-1). Real-time polymerase chain reaction (PCR) was used to determine gene expression of inducible nitric oxide synthase (iNOS) and insulin receptor (INS-R). RESULTS Exposure to FA decreased iGSH and NO levels in Hep-G2 cells and increased MDA and PAI-1 production. Gene expression of iNOS and INS-R in Hep-G2 cells was decreased by exposure to FA. Co-incubation with NAC and GSH prevented the change of iNOS mRNA levels, but not of INS-R; co-incubation with ADN restored the gene expression of INS-R, but not of i-NOS. ADN prevented also the FA-induced increase in MDA in cultured human endothelial cells. CONCLUSION Exposure to FA activates oxidative stress and production of prothrombotic markers and decreases expression of insulin receptors in cultured human hepatocytes. These effects of FA are partially prevented by ADN and might contribute to the increased cardiovascular risk in patients with NAFLD and metabolic syndrome.

Abstract
Activated platelets express CD40L on their plasma membrane and release the soluble fragment sCD40L. The interaction between platelet surface CD40L and endothelial cell CD40 leads to the activation of endothelium contributing to atherothrombosis. Few studies have directly demonstrated an increased expression of platelet CD40L in conditions of in vivo platelet activation in humans, and no data are available on its relevance for endothelial activation. We aimed to assess whether platelets activated in vivo at a localized site of vascular injury in humans express CD40L and release sCD40L, whether the level of platelet CD40L expression attained in vivo is sufficient to induce endothelial activation, and whether platelet CD40L expression is inhibited by aspirin intake. We used the skin-bleeding-time test as a model to study the interaction between platelets and a damaged vessel wall by measuring CD40L in the blood emerging from a skin wound in vivo in healthy volunteers. In some experiments, shed blood was analyzed before and 1 h after the intake of 500 mg of aspirin. Platelets from the bleeding-time blood express CD40L and release soluble sCD40L, in a time-dependent way. In vivo platelet CD40L expression was mild but sufficient to induce VCAM-1 expression and IL-8 secretion in coincubation experiments with cultured human endothelial cells. Moreover, platelets recovered from the bleeding-time blood activated endothelial cells; an anti-CD40L antibody blocked this effect. On the contrary, the amount of sCD40L released by activated platelets at a localized site of vascular injury did not reach the concentrations required to induce endothelial cell activation. Soluble monocyte chemoattractant protein-1, a marker of endothelium activation, was increased in shed blood and correlated with platelet CD40L expression. Aspirin intake did not inhibit CD40L expression by platelets in vivo. We concluded that CD40L expressed by platelets in vivo in humans upon contact with a damaged vessel wall activates endothelium; aspirin treatment does not inhibit this mechanism.

Abstract
Alcohol-induced endothelial changes might contribute to an increase in blood pressure in regular alcohol consumers. Some antihypertensive drugs affect oxidative stress and endothelial function and might counteract the effects of alcohol at the cellular level. The aim of this study was to investigate in vitro the effects of three different types of antihypertensive agents on alcohol-induced endothelial responses and oxidative stress. Cultured human endothelial cells were exposed to increasing concentrations (1, 10, 60 micromol/L) of zofenoprilat, carvedilol, and lacidipine in the absence and in the presence of ethanol (140 mmol/L). Concentrations of endothelin (ET) and nitric oxide (NO) were measured in the culture media as markers of endothelial function, and malondialdehyde (MDA) and intracellular glutathione (GSHi) were measured as markers of oxidative stress. Exposure to alcohol increased the levels of ET, NO, and MDA, and decreased GSHi. Carvedilol and zofenoprilat were more effective than lacidipine in counteracting the effects of alcohol on ET production. Alcohol-induced NO production was enhanced by carvedilol, whereas zofenoprilat and lacidipine did not have a significant effect. The alcohol-induced increase in MDA concentrations was blunted by all three drugs, but only carvedilol restored a normal response. All three drugs increased GSHi levels, with the effect being greater for carvedilol and lacidipine than zofenoprilat. Carvedilol is more effective than zofenoprilat and lacidipine in counteracting alcohol-induced endothelial responses in vitro and in decreasing oxidative stress. These effects might be particularly beneficial in patients with alcohol-related hypertension.

Abstract
BACKGROUND Although heavy alcohol drinkers are at an increased risk of developing cardiovascular events, moderate alcohol intake is associated with reduced incidence of cardiovascular death. This paradox might reflect a dose-related effect of different alcohol intakes on endothelial function and this, in turn, might depend on changes in oxidative stress. METHODS We tested the effects of alcohol withdrawal in heavy alcohol consumers and compared the plasma levels of endothelin-1, nitric oxide, plasminogen activator inhibitor-1, von Willebrand factor, malondialdehyde, and intracellular glutathione with those of alcoholics that did not modify their alcohol intake and teetotalers. In human endothelial cells that had been cultured for 2 weeks in the presence of different concentrations of ethanol, we assessed the same parameters after withdrawal of ethanol exposure. RESULTS Alcohol increased the levels of endothelin-1, nitric oxide, and plasminogen activator inhibitor-1 and decreased the levels of von Willebrand factor both in vivo and in vitro. These changes were dose dependent, rapidly reversed after withdrawal of exposure, and associated with the presence of increased oxidative stress as indicated by increased levels of both malondialdehyde and intracellular glutathione. Blockade of oxidative stress by incubation of endothelial cells in the presence of oxidants' scavengers prevented the alcohol-induced functional modifications of the endothelium. CONCLUSIONS Alcohol affects endothelial function with an effect that is mediated by an activated oxidative stress and is rapidly reversed after withdrawal. Dose-related endothelial responses to different alcohol intakes might translate in either vascular protection or vascular damage.

Abstract
The use of arterial homografts in clinical practice is becoming increasingly common, yet there is an urgent need to address one of the most well-established problems associated with their use: the loss of integrity of the endothelium following cryopreservation. The partial lack of endothelium causes contact between the extracellular matrix and blood flow, which, in turn, often gives rise to thrombosis and/or restenosis. Our objective was first to attempt to replace the arterial endothelial cells lost during the cryopreservation process by seeding autologous venous endothelial cells, and to evaluate the behaviour of venous and arterial endothelial cells in co-culture. The idea was to establish whether venous endothelial cells would be accepted by arterial endothelial cells and could therefore be used to restore the endothelial lining for the subsequent use of these vessels in in vivo grafting procedures. For the co-culture experiments, endothelial cells were obtained from the jugular vein and both iliac arteries of the minipig by treatment with 0.1% type I collagenase. The venous endothelial cells were fluorescently labelled with the membrane intercalating dye PKH26. Equal numbers of venous and arterial endothelial cells were mixed and co-cultured for 24h, 48h or 4 days. Cell viability, determined by 2% trypan blue staining and the TUNEL method, was established before and after fluorescence labelling. Cellular activity was determined by estimating PGI2 levels in the cultures. The proliferation index was established by [H(3)]thymidine (1muCi/ml) in the cell culture medium. For the in vivo tests, 5 cm length segments of minipig iliac artery were used to establish the groups: control (n = 6), fresh arterial segments; group I (n = 16), cryopreserved arterial segments and group II (n = 16), cryopreserved arterial segments seeded with autologous venous endothelial cells. The cryopreserved vessels in group II were seeded by flooding with a labelled venous endothelial cell suspension. Once seeded, the arterial segments were included in an in vitro flow circuit. All the specimens were processed for fluorescence and light microscopy, and scanning electron microscopy. The denuded endothelial surface was determined in each group. Cell death was evaluated by the TUNEL method. We confirmed the existence of intercellular PECAM1-type junctions between venous (PKH26+) and arterial cells in co-culture and the functional activity of the cells. The cryopreserved arterial segments showed a well-preserved wall structure. However, different size areas of marked endothelial denudation were detected. After seeding with labelled cells (PKH26+), these denuded areas of the cryopreserved artery were entirely covered by fluorescent cells. After seeding, a drop in the proportion of damaged endothelial cells was recorded. Despite some loss of seeded cells after inclusion in the in vitro flow circuit, the endothelial cell count was not significantly different to those recorded for control, non-cryopreserved specimens. In conclusion arterial and venous endothelial cells growing in co-culture modify their behaviour to form multilayers. The two cell populations form normal PECAM1 junctions and preserve their functional properties. Seeding autologous venous endothelial cells on the luminal surface of cryopreserved arterial segments serves to restore the integrity of the endothelial layer.

Abstract
Several thrombogenic abnormalities are associated with diabetes. Since endothelial dysfunction occurs at early stages of disease, it may reflect pathophysiological changes that are responsible for alterations in vascular structure, growth and modifications of adhesivity to platelets and leukocytes, leading to atherosclerosis and thrombosis. Predisposing factors of vascular diseases, such as diabetes, are also associated with endothelial dysfunction. Restoration or replacement of endothelium-related factors like nitric oxide impede the progression of vascular thrombogenic diseases, and prevent the action of vasoconstrictor factors such as endothelin or other prothrombotic factors such as plasminogen-activator inhibitor-1. Since high glucose concentration in blood is the hallmark of diabetes and because the vascular lesions of atherosclerosis are localized in large artheries, we have cultured endothelial cells from the human aorta. Two endothelial cell strains from the same aortic tract that show different characteristics and behavior in high glucose were isolated. Such findings reflect the importance to have well characterized and standardized cell culture systems to carry out experiments to study the glucose-dependent atherosclerotic process in vitro. Our cell strains may represent a useful in vitro model to study the complex pathophysiology of diabetes-related atherosclerosis.

Abstract
Hepatic artery thrombosis is a major cause of graft failure in liver transplantation. Use of donor interponates are common, but results are controversial because of necrosis or thrombosis after rejection. Reperfusion injury, hypoxia and free radical production determinate the survival. The aim of the study was to create an 'ideal' arterial interponate. Autologous, tubular graft lined with mesothelial cells, prepared from the posterior rectus fascia sheath, was used for iliac artery replacement in eight mongrel dogs for six months under immunosuppression. Patency rate was followed by Doppler ultrasound. Eight grafts remained patent and another two are patent after one year. The patency rate was good (median Doppler flow: 370 cm/sec) and there was no necrosis, thrombosis or aneurysmatic formation. The grafts showed viable morphology with neoangiogenesis, appearance of elastin, smooth muscle and endothelial cells. Electron microscopy showed intact mitochondrial structures without signs of hypoxia. Tissue oxygenation was good in all cases with normal (< 30 ng/ml) myeloperoxidase production. In conclusion, this autologous graft presents good long-term patency rate. Viability, arterialisation and low thrombogenicity are prognostic factors indicating usability of the graft in the clinical practice without the risk of rejection. Further investigations such as cell cultures and standardisation are necessary.

Abstract
vasodilative Thyroid diseases have been associated with pathophysiological changes in the vasculature that may result from altered thyroid hormone production or to direct effect of elevated thyrotropin (TSH) levels on smooth muscle cells. A direct effect of TSH on vascular endothelium has not been considered. In the present study a strain of human aortic endothelial cells has been stimulated with TSH, and vascular parameters correlated with the atherosclerotic process have been analyzed. Addition of TSH induced an increase of cyclic AMP (cAMP) concentration in human aortic endothelial cells. Furthermore it induced a decrease of endothelin (from 30 +/- 2.5 to 13 +/- 1 fmol/mL) and of tissue plasminogen activator secretion (from 2,800 +/- 200 to 1,600 +/- 150 ng/mL). On the other hand, it increased nitric oxide (from 148 +/- 8 to 211 +/- 12 microM). TSH did not affect plasminogen activator inhibitor 1. Similar results were obtained when immunoglobulin Gs (IgGs) from Graves' disease patients were used. In conclusion, our findings suggest that TSH and IgGs from Graves' disease patients could stimulate endothelial cells, increasing the secretion of procoagulant and vasodilative factors, and that cAMP is involved in the transduction pathway. These findings are consistent with modifications of the fibrinolytic system reported in hypothyroidism and in Graves' disease. On the other hand, the increase of vascular resistance found in patients with hypothyroidism may be due to the altered thyroid hormone production and not to TSH directly, or to a different effect of TSH on peripheral vessels.
