内皮细胞是覆衬于全身血管和淋巴管内面的单层扁平细胞,具有多种生理功能,它做为组织与血液间的第一道屏障,在血管通透性调节中发挥重要作用。内皮细胞生长状态的好坏是其能否执行这些功能的先决条件,所以,在缺氧的条件下,研究内皮细胞尤其是肺内皮细胞(ＰＡＥＣ)的生长状态变 Endothelial cells are monolayers of flat cells that line the surface of systemic blood vessels and lymphatic vessels and have multiple physiological functions. As the first barrier between tissue and blood, endothelial cells play an important role in the regulation of vascular permeability. Endothelial cell growth status is a prerequisite for its ability to perform these functions, so under hypoxic conditions, the study of endothelial cells, especially the growth of pulmonary endothelial cells (PAEC) state change
