Expression of NPC markers and Notch pathway in NPC exosome-treated MSCs. (a) Gene expression of NPC markers (collagen II, Aggrecan, and Sox9) was significantly upregulated in exosome-treated MSCs in 7, 14, and 21 days. (b) Expression of related protein was normalized to GAPDH. (c) Expression of Notch pathway-related genes in exosome-treated MSCs was detected by qRT-PCR. (d) Western blot analysis of Notch pathway-related protein in exosome-treated MSCs. All data were showed as . . , , and .
