Fig. 4From: Comprehensive analysis of skeletal muscle- and bone-derived mesenchymal stem/stromal cells in patients with osteoarthritis and femoral neck fractureGrowth kinetics and senescence. The cells were further culture-expanded after the CFU-F assays at p0 and maintained in culture to determine the growth kinetics, including growth rate (a) and doubling time (b). The rate of senescence determined by the β-galactosidase staining was determined at p3/p4 for the muscle and bone-derived MSCs of all three donor groups (c)Back to article page
