Doubling time of these cells were estimated about 30 hours and cell cycle analysis revealed that the majority of cells (over 80 percents) stood in G0-G1 phase while a small population of cells was in (S+G2+M) phase.

• 细胞周期分析表明80%25以上的细胞都处于G0~G1期。 流式细胞检测表明这些细胞表达CD13、CD29、CD44、CD90、CD105和CD166等MSCs标志物。
