[Abstract] Cell-cell adhesion ensures tight contacts between neighbouring cells, which is necessary for cell segregation, as well as for the morphological and functional differentiation of different tissues. Evidently there are cell-cell recognition systems that make cells of the same type preferentially adherent to one another. Homotypic cell adhesion is particularly important in mediating a range of physiological processes such as cell survival, migration and remodeling of vessels. Thus in the present study we selected two populations of endothelial progenitor cells which are from the same donor to investigate the possible effect of a small molecule compound Icariin on homotypic cell adhesion. Many angiogenic factors can destabilize the organization of intercellular junctions, causing endothelial ...
[摘要] 细胞粘附保证了相邻细胞之间的紧密接触，这对于细胞分离以及不同组织的形态和功能分化是必要的。显然，存在使相同类型的细胞优先彼此粘附的细胞 - 细胞识别系统。同型细胞粘附在介导一系列生理过程例如细胞存活，迁移和血管重塑中特别重要。因此，在本研究中，我们选择两个来自相同供体的内皮祖细胞群体，以研究小分子化合物Icariin对同型细胞粘附的可能影响。许多血管生成因子可以破坏细胞间连接的组织，导致内皮屏障开放。在本研究中，我们观察到Icariin治疗减少EPC中VE-钙粘蛋白表达的水平，表明细胞 - 细胞粘附减少 - 证明Icariin的促血管生成作用。总之，所观察到的EPCs的同型粘附的丧失可能有助于由Icariin施加的增强的血管生成作用。
