Figure 7. Distribution of SC populations dynamically changes in vivo.

SC were isolated from LD muscles of 4-day-old (n = 7) or 14-day-old piglets (n = 4). In the younger animals, P50/70 cells represent the dominant subpopulation, whereas in older piglets, cells from P40/50 are preferentially found. The relation of both subpopulations is significantly different in younger and older piglets. Bars represent mean ± SD. For statistical analysis, Mann-Whitney Rank Sum Test was performed, *p ≤ 0.05.
