RESUMEN
Endothelial cell proliferation rate is an important indicator of vascular health. Being able to detect the rate of endothelial cell proliferation, or cell cycle disturbances after intervention is a valuable tool for analysing any beneficial or detrimental effects of treatments in vitro. Here, we describe a straightforward flow cytometric-based method of proliferation and cell cycle tracking that can be performed on human endothelial cells in culture over several days.

Angiogenesis is essential for wound healing and regeneration and plays a significant role in several pathologies including cancer and atherosclerosis. In vitro assays offer simple and powerful tools for investigating the regulation of the angiogenic functions of primary endothelial cells (ECs) before moving to in vivo studies. The classic in vitro two-dimensional angiogenesis assay utilizes Basement Membrane Extract (BME) to study the differentiation and sprouting of ECs over a 24-h period. The protocol described here details a thin layer BME adaptation of the angiogenesis assay requiring significantly less BME and carried out in 96-well plates, allowing for a larger data yield at a greatly reduced cost, while maintaining the robustness of an assay used extensively over the past three decades.
