Effects of hDPSC-EVs on the MAPK pathway in hADSCs. (a) ALP staining of hADSCs after treatment with hDPSC-EVs and/or inhibitors. (b) Quantitative detection of ALP activity of hADSCs treated with hDPSCEVs and/or inhibitors. (c–e) Protein expression of p-P38/P38, p-ERK 1/2 1/2/ERK 1/2, and p-JNK/JNK, determined by western blotting. (f–h) The ratios of p-P38/P38, p-ERK 1/2 1/2/p-ERK 1/2, and p-JNK/JNK intensity. SB: SB203580, inhibitor of P38; PD: PD98059, inhibitor of ERK 1/2; and SP: SP600125, inhibitor of JNK. Data are presented as the mean ± standard deviation of the mean (n = 3), ** represents p < 0.01.
