Fig. 4From: Platelet-rich plasma activates AKT signaling to promote wound healing in a mouse model of radiation-induced skin injuryHistologic features of radiation skin-injury mouse model. a Comparative images of PRP-treated and untreated irradiated skin (H&E stain) at day 7, 14, and 28. b K10/K14 positivity on immunostain (note epithelial tongues) in irradiated skin at day 14. c Quantification of type III collagen in irradiated skin at day 14 (Picrosirius Red stain). Results of one experiment performed in triplicate and expressed as mean ± SEM *p < 0.05 vs. 40-Gy group; and d gland-like structures (arrows) encountered in recovering skin at day 28 (Oil Red O stain).
