Wound healing assay. scNT-MUC-derived PUVECs (e and f) had significantly lower levels of cell migration than control (a and b) and scNT-N (c and d) PUVECs. The graph shows the number of cells that migrated into the wound 24 hr after wounding. The data were expressed as the mean value of cell numbers measured in individual control, scNT-N and scN-MUC with at least 3 independent experiments. * P < 0.05.
