Surface marker expression of in-vitro aging MSCs. MSCs were cultivated with either DMEM-based (a) or αMEM-based (b) expansion media and were analyzed by flow cytometry for the expression of specific MSC positive (Stro-1, CD29, CD44, CD73, CD90, CD105, CD106, CD 146) and negative (CD34, CD45) surface antigens. n = 4–6; *p < 0.05, versus the corresponding P8-MSCs cultured under the same expansion condition within the same surface marker analysis. αMEM, minimum essential medium alpha; DMEM, Dulbecco’s modified Eagle’s medium
