FIG. 2.
In vitro cellular growth kinetics. (A) There was no difference in the cellular growth curves of the two groups over 60 h. (B) No differences were found in mitotic fractions between stimulated and nonstimulated MDSCs. (C) Stimulated MDSCs showed a significantly lower division time when compared with the controls. *Significantly different than nonstimulated controls (p = 0.03). (D) Live automated cell imaging system pictures after 60 h of proliferation. MDSCs, muscle-derived stem cells.
