Abstract
Perivascular cells represent an in vivo counterpart of mesenchymal stromal/stem cells that populate the outer layer of blood vessels. Pericytes in capillaries and microvessels and adventitial cells of large arteries and veins give rise to stem/progenitor cells when isolated and cultured in vitro. These cells have been considered candidate cell types for cell therapy. Adipose tissue, being highly vascularized, dispensable, and easily accessed, is a viable option to obtain perivascular cells for use in research and in clinical trials. Here, we describe our established protocol to extract perivascular cells from human fat through fluorescence-activated cell sorting, which allows for the isolation of defined populations of progenitor cells with high reproducibility.
