Aging Induced p53/p21 in Genioglossus Muscle Stem Cells and Enhanced Upper Airway Injury

Figure 3

The proliferation and migration of GG MuSCs declined with aging. (a) Primary cells were obtained from GG muscle fibers, and cells showed a spindle morphology. (b) GG MuSC markers Pax7 and MyoD were positive in cells. (c) Wound healing of GG MuSCs derived from four age groups. (d) The migration of GG MuSCs derived from four age groups. (e) The wound healing and migration rate are significantly lower in 12-month-old compared to other age groups at 24 h. (f) The growth curve of GG MuSCs in four age groups. and . Scale bars are 100 μm.
