Comparative analysis of CD34 and CD38 expression of highly purified CD34+CD38−Lin− cells after 4 d of culture in the presence of BMPs. A representative experiment (n = 3) of CD34 and CD38 cell surface expression performed on initially purified CD34+CD38−Lin− cells after 4 d of culture in serum-free conditions or with the addition of factors as indicated. The entire contents of individual wells were collected at 4 d, stained with mAbs, and analyzed using flow cytometric analysis.
