Aim: to evaluate the immunophenotype of adipose tissue stem cells isolated from epicardial and perivascular fat depots in patients with coronary heart disease and acquired heart defects. Results: In cell culture obtained from epicardial adipose tissue (EAT) and perivascular adipose tissue (PVAT) (2nd passage) in patients with both coronary heart disease and acquired heart defects, a high (over 90%) expression of membrane proteins characteristic of stem cells. In addition to the main population, with both in the EAT culture and in the PVAT, there were 2 minor ones: 1 – CD90-, CD105+, CD34-/+, CD73+, CD45- is presumably endothelial population, 2 – CD90+, CD105-, CD34-, CD73-, CD45- is the smallest population. Conclusion: In the early stages of cultivation, cells of the stromal vascular fraction isolated from epicardial and perivascular adipose tissue express surface markers characteristic of adipose tissue stem cells.
