sEV-AT accelerated de novo adipogenesis. A H&E staining showed the progress of de novo adipogenesis prompted by sEV-AT and ATE. The hollow arrows represented the neoadipose tissue. The solid black arrows represented the new blood vessels, the asterisk represented the Matrigel. B, C The area percentage of the neoadipose tissue (B) and new blood vessels (C) in sEV-AT or ATE groups. Data were represented as mean ± SEM. n = 3. *p < 0.05, **p < 0.01, ***p < 0.001, ****p < 0.0001
