From: Adipose-derived stem cells attenuate acne-related inflammation via suppression of NLRP3 inflammasome
ADSCs inhibit skin inflammation in the mouse ear acne model. P. acnes (1 × 108 colony-forming units/ml), PBS, or ADSCs (1 × 108) were intradermally injected into the ears (50 ul in each ear) of C57BL/6 mice (6–8 weeks old). A P. acnes-induced redness evaluated 24 h after injection. B H&E staining of ear tissue sections (×40, ×100, and ×400). C Ear thickness measured with a vernier caliper at 24 h after injection. n = 6; *p < 0.05; **p < 0.01; ***p < 0.001
