Figure Lengend Snippet: Cxcl14 enhances muscle regeneration in aging mice. ( a ) TA muscles were injured with BaCl 2 , and isolated on day 7 AI. Upon cryosection, H&E staining was performed and regenerating myofiber cross-sectional area (CSA) was quantified ( n =12 for 4 months, n =9 for 6 months, n =11 for 8 monrhs, n =12 for 12 months, n =6 for 18 months). ( b ) TA muscle sections as described in ( a ) were isolated on day 7 AI, and the RNA was isolated and quantified by qRT-PCR. Horizontal bars represent the mean of individually plotted data points ( n =15 for 4 months, n =11 for 6 months, n =12 for 8 months, n =12 for 12 months, n =6 for 18 months). ( c ) TA muscles from 2-month-old (young) and 12-month-old (aged) mice were co-injected with Cxcl14 or scramble shRNA viruses together with BaCl 2 , then processed as in ( a ) at day 7 and day 14 AI ( n =6 for each). One-way ANOVA was used to analyze the data in ( b ) and paired two-tailed t -test was performed in ( c ). The data denoted by different letters ( a – c ) are significantly different from each other ( P <0.05). All error bars represent s.d. of independent replicates. Scale bar: 50 μm.
