Aging Induced p53/p21 in Genioglossus Muscle Stem Cells and Enhanced Upper Airway Injury
Figure 1
The structure and function of GG declined with aging. (a) The cross-sectional area of muscle fiber in 2-month-old significantly increased compared to other age groups. (b) The collagen content of 2-month-old was the highest among four age groups mice. (c) The genioglossus electromyographic activity in four age groups. , , and . Scale bars are 100 μm.
