Angiogenesis is a complicated process, which is regulated by numerous cytokines and growth factors. Besides, the interaction of endothelial cells
with extracellular matrix components, with other cell types and with each other is essential for the formation on new blood vessels. The initiation, continuation and
completion of angiogenesis depend on the balance of pro- and antiangiogenic factors in the endothelium microenvironment. Factors that influence endothelial cell
proliferation are necessary for vascular development and their normal functioning. The influence of new pharmaceutical agents on angiogenesis is commonly
evaluated by results of in vivo assays, i. e. chick chorioallantoic membrane and rabbit cornea assays. However, reported results are not always objective.
So, the aim of our study was to elaborate methods of estimation of endothelial cell proliferation as one of important stages of angiogenesis.
Key words: angiogenesis, endothelial cells, proliferation
