PDGFRβ lineage cells from young and old mice have distinct properties. A Images representing the cell morphology of the mT + and mG + cell populations isolated from 5 weeks and 1-year-old mice. B IF staining for Pax7 on mG + muscle cells isolated from 5 weeks and 12-month-old mice. C Quantification of MPC-like and MSC-like cells in young and old skeletal muscles (n = 6). Error bars indicate ‘mean ± SD,’ *p < 0.05. Scale bars in panel A = 50 µm, panel B = 25 µm
