Apoptosis is induced in MSCs under H/SD conditions. (A and B) Cell surface makers of MSCs. (C–E) Analysis of apoptosis using flow cytometry for (D) early apoptotic cells and (E) necrotic or apoptotic cells in the terminal stages induced by H/SD in MSCs. Data are presented as the means ± SD of 3 separate experiments. *P<0.05, compared with the normal group. MSCs, mesenchymal stem cells; H/SD, hypoxia/serum deprivation.
