Injected ASCs persist at the site of 35 Gy irradiation. (A): Retention at day 1of injected GFP⁺ Luc⁺ ASCs at the right hind limb-irradiated site and continuous persistence out to 77 days postirradiation. In contrast, the unirradiated left hind limb showed less retention of the same number of injected cells at days 49 and 77. (B): Single-cell suspensions from explanted irradiated skin were cultured at day 77 and GFP⁺ cells were counted per 100 cells (image magnification ×10). *, p < .05; **, p < .01. Abbreviation: ASC, adipose-derived stem cell.
