The HDMEC I purchased from PromoCell seem to contain 2 different cell morphologies. How is this possible? What's the purity of HDMEC cultures guaranteed by PromoCell?
Description
Our HDMEC are isolated from the dermis of juvenile foreskin or adult skin. The purity is > 95%. Since the dermis contains blood and lymphatic capillaries; HDMEC cultures comprise blood and lymphatic microvascular endothelial cells that have differing morphologies. Both cell types have a common origin and can be identified by several markers. The ratio of lymphatic and blood derived endothelial cells can vary from lot to lot and is not determined at PromoCell.
