The walls of capillaries are composed of a single layer of microvascular endothelial cells. These cells differ in morphology and other properties depending on the tissues the capillaries supply. Therefore,Gentaur offers a range of Microvascular Endothelial Cells produced at Gentaur's cell culture facility from normal human tissues of different origins.Shortly after isolation, all Gentaur Microvascular Endothelial Cells are cryopreserved at passage 2 (P2) using Gentaur's proprietary, serum-free freezing medium, Cryo-SFM. Each cryo vial contains more than 500,000 viable cells after thawing.Proliferating cell cultures are made from 500,000 cryopreserved cells that have been thawed and cultured for three days at Gentaur.
