Colony-forming efficiency of MSCs. Colony-forming efficiency (CFE) of P5 MSCs from different sources (A) and 9004 BM-MSC cultured to passages 10, 15 and 20 (B). CFE is expressed as percentage of colonies formed per total cells plated and presented as means (± SEM). Statistically significant groups by Tukey’s test are indicated by letters (P < 0.05).
