The change of miR-30c-5p in the process of VSMC differentiation and in DA. Adventitial Sca-1⁺ progenitor cells were induced by TGF-β1. The shape of the cells was observed under the microscope at different time points (0 h, 2 h, 4 h, 6 h, 8 h, 10 h, 12 h, 24 h) (a); the expression of SMαA (b), SM22α (c), SMMHC (d), and miR-30c-5p (e) were detected by RT-qPCR. The expression of miR-30c-5p in HA and DA were detected by RT-qPCR (f) (*P < 0.05, ** P < 0.01, ns P ≥ 0.05)
