Characterization of Endothelial and Smooth Muscle Cells From Different Canine Vessels.

ABSTRACT: Vasculature performs a critical function in tissue homeostasis, supply of oxygen and nutrients, and the removal of metabolic waste products. Vascular problems are implicated in a large variety of pathologies and accurate in vitro models resembling native vasculature are of great importance. Unfortunately, existing in vitro models do not sufficiently reflect their in vivo counterpart. The complexity of vasculature requires the examination of multiple cell types including endothelial cells (ECs) and vascular smooth muscle cells (VSMCs), as well as vessel location in the body from which they originate. The use of canine blood vessels provides a way to study vasculature with similar vessel size and physiology compared to human vasculature. We report an isolation procedure that provides the possibility to isolate both the endothelial and smooth muscle cells from the same vessels simultaneously, enabling new opportunities in investigating vasculature behavior. Canine primary ECs and VSMCs were isolated from the vena cava, vena porta and aorta. All tissue sources were derived from three donors for accurate comparison and to reduce inter-animal variation. The isolation and purification of the two distinct cell types was confirmed by morphology, gene- and protein-expression and function. As both cell types can be derived from the same vessel, this approach allows accurate modeling of vascular diseases and can also be used more widely, for example, in vascular bioreactors and tissue engineering designs. Additionally, we identified several new genes that were highly expressed in canine ECs, which may become candidate genes for novel EC markers. In addition, we observed transcriptional and functional differences between arterial- and venous-derived endothelium. Further exploration of the transcriptome and physiology of arteriovenous differentiation of primary cells may have important implications for a better understanding of the fundamental behavior of the vasculature and pathogenesis of vascular disease.

Project description:Collaterals are unique blood vessels present in the microcirculation of most tissues that, by cross-connecting a small fraction of the outer branches of adjacent arterial trees, provide alternate routes of perfusion. However, collaterals are especially susceptible to rarefaction caused by aging, other vascular risk factors, and mouse models of Alzheimer's disease-a vulnerability attributed to the disturbed hemodynamic environment in the watershed regions where they reside. We examined the hypothesis that endothelial and smooth muscle cells (ECs and SMCs, respectively) of collaterals have specializations, distinct from those of similarly-sized nearby distal-most arterioles (DMAs) that maintain collateral integrity despite their continuous exposure to low and oscillatory/disturbed shear stress, high wall stress, and low blood oxygen. Examination of mouse brain revealed the following: Unlike the pro-inflammatory cobble-stoned morphology of ECs exposed to low/oscillatory shear stress elsewhere in the vasculature, collateral ECs are aligned with the vessel axis. Primary cilia, which sense shear stress, are present, unexpectedly, on ECs of collaterals and DMAs but are less abundant on collaterals. Unlike DMAs, collaterals are continuously invested with SMCs, have increased expression of Pycard, Ki67, Pdgfb, Angpt2, Dll4, Ephrinb2, and eNOS, and maintain expression of Klf2/4. Collaterals lack tortuosity when first formed during development, but tortuosity becomes evident within days after birth, progresses through middle age, and then declines-results consistent with the concept that collateral wall cells have a higher turnover rate than DMAs that favors proliferative senescence and collateral rarefaction. In conclusion, endothelial and SMCs of collaterals have morphologic and functional differences from those of nearby similarly sized arterioles. Future studies are required to determine if they represent specializations that counterbalance the disturbed hemodynamic, pro-inflammatory, and pro-proliferative environment in which collaterals reside and thus mitigate their risk factor-induced rarefaction.

Project description:IntroductionPluripotent stem cells have been used by various researchers to differentiate and characterize endothelial cells (ECs) and vascular smooth muscle cells (VSMCs) for the clinical treatment of vascular injuries. Studies continue to differentiate and characterize the cells with higher vascularization potential and low risk of malignant transformation to the recipient. Unlike previous studies, this research aimed to differentiate induced pluripotent stem (iPS) cells into endothelial progenitor cells (EPCs) and VSMCs using a step-wise technique. This was achieved by elucidating the spatio-temporal expressions of the stage-specific genes and proteins during the differentiation process. The presence of highly expressed oncogenes in iPS cells was also investigated during the differentiation period.MethodsInduced PS cells were differentiated into lateral mesoderm cells (Flk1+). The Flk1+ populations were isolated on day 5.5 of the mesodermal differentiation period. Flk1+ cells were further differentiated into EPCs and VSMCs using VEGF165 and platelet-derived growth factor-BB (PDGF-BB), respectively, and then characterized using gene expression levels, immunocytochemistry (ICC), and western blot (WB) methods. During the differentiation steps, the expression levels of the marker genes and proto-oncogenic Myc and Klf4 genes were simultaneously studied.ResultsThe optimal time for the isolation of Flk1+ cells was on day 5.5. EPCs and VSMCs were differentiated from Flk1+ cells and characterized with EPC-specific markers, including Kdr, Pecam1, CD133, Cdh5, Efnb2, Vcam1; and VSMC-specific markers, including Acta2, Cnn1, Des, and Myh11. Differentiated cells were validated based on their temporal gene expressions, protein synthesis, and localization at certain time points. Significant decreases in Myc and Klf4 gene expression levels were observed during the EPCs and VSMC differentiation period.ConclusionEPCs and VSMCs were successfully differentiated from iPS cells and characterized by gene expression levels, ICC, and WB. We observed significant decreases in oncogene expression levels in the differentiated EPCs and VSMCs. In terms of safety, the described methodology provided a better safety margin. EPCs and VSMC obtained using this method may be good candidates for transplantation and vascular regeneration.

Project description:?-Catenin phosphorylation plays important roles in modulating its functions, but the effects of different phosphorylated forms of ?-catenin in response to heterocellular interaction are unclear. Here we investigated whether distinct modes of phosphorylation on ?-catenin could be triggered through heterocellular interactions between endothelial cells (ECs) and smooth muscle cells (SMCs), and the consequent modulation of EC functions. ECs were cocultured with SMCs to initiate direct contact and paracrine interaction. EC-SMC coculture induced EC ?-catenin phosphorylations simultaneously at tyrosine 142 (Tyr142) and serine 45/threonine 41 (Ser45/Thr41) at the cytoplasm/nuclei and the membrane, respectively. Treating ECs with SMC-conditional medium induced ?-catenin phosphorylation only at Ser45/Thr41. These findings indicate that different phosphorylation effects of EC-SMC coculture were induced through heterocellular direct contact and paracrine effects, respectively. Using specific blocking peptides, antagonists, and siRNAs, we found that the ?-catenin Tyr142-phosphorylation was mediated by connexin 43/Fer and that the ?-catenin Ser45/Thr41-phosphorylation was mediated by SMC-released bone morphogenetic proteins through VE-cadherin and bone morphogenetic protein receptor-II/Smad5. Transfecting ECs with ?-catenin-Tyr142 or -Ser45 mutants showed that these two phosphorylated forms of ?-catenin modulate differential EC function: The Tyr142-phosphorylated ?-catenin stimulates vascular cell-adhesion molecule-1 expression to increase EC-monocytic adhesion, but the Ser45/Thr41-phosphorylated ?-catenin attenuates VE-cadherin-dependent junction structures to increase EC permeability. Our findings provide new insights into the understanding of regulatory complexities of distinct modes of ?-catenin phosphorylations under EC-SMC interactions and suggest that different phosphorylated forms of ?-catenin play important roles in modulating vascular pathophysiology through different heterocellular interactions.

Project description:Thrombin is a procoagulant inflammatory agonist that can disrupt the endothelium-lumen barrier in the lung by causing contraction of endothelial cells and promote pulmonary cell proliferation. Both contraction and proliferation require increases in cytosolic Ca(2+) concentration ([Ca(2+)](cyt)). In this study, we compared the effect of thrombin on Ca(2+) signaling in human pulmonary artery smooth muscle (PASMC) and endothelial (PAEC) cells. Thrombin increased the [Ca(2+)](cyt) in both cell types; however, the transient response was significantly higher and recovered quicker in the PASMC, suggesting different mechanisms may contribute to thrombin-mediated increases in [Ca(2+)](cyt) in these cell types. Depletion of intracellular stores with cyclopiazonic acid (CPA) in the absence of extracellular Ca(2+) induced calcium transients representative of those observed in response to thrombin in both cell types. Interestingly, CPA pretreatment significantly attenuated thrombin-induced Ca(2+) release in PASMC; this attenuation was not apparent in PAEC, indicating that a PAEC-specific mechanism was targeted by thrombin. Treatment with a combination of CPA, caffeine, and ryanodine also failed to abolish the thrombin-induced Ca(2+) transient in PAEC. Notably, thrombin-induced receptor-mediated calcium influx was still observed in PASMC after CPA pretreatment in the presence of extracellular Ca(2+). Ca(2+) oscillations were triggered by thrombin in PASMC resulting from a balance of extracellular Ca(2+) influx and Ca(2+) reuptake by the sarcoplasmic reticulum. The data show that thrombin induces increases in intracellular calcium in PASMC and PAEC with a distinct CPA-, caffeine-, and ryanodine-insensitive release existing only in PAEC. Furthermore, a dynamic balance between Ca(2+) influx, intracellular Ca(2+) release, and reuptake underlie the Ca(2+) transients evoked by thrombin in some PASMC. Understanding of such mechanisms will provide an important insight into thrombin-mediated vascular injury during hypertension.
