Proliferation (A) and migration of FHUVECs and MHUVECs (B, C). Linear regression analysis (A) of the proliferation of FHUVECs (▲, n = 10) and MHUVECs (▄, n = 7). *The comparison of the two slopes indicates that the slopes are different (P < 0.001). (B) Representative photographs of wound closure at 0, 9 and 24 h taken at × 4 magnification. (C) Mean of basal migratory capacity of MHUVECs (▄, n = 8) and FHUVECs (▲, n = 9). The data are expressed as median percentage of wound closure + MAD compared with the initial area (0 h). *P = 0.024.
