Role of pantothenic and ascorbic acid in wound healing processes: in vitro study on fibroblasts

In order to analyze the possible role of pantothenic acid (PA) and ascorbic acid (AA) in wound healing processes, the effects of these vitamins upon the growth of fibroblasts, obtained from human fetal skin or foreskin, were studied. Cell proliferation, protein synthesis and protein release were evaluated. The rate of cell growth remained identical when PA or AA were added to the culture medium. PA increased the basal incorporation of 14C proline into precipitated material while AA did not modify this action. However, when cultures were incubated with PA and AA, the release of intracellular protein into the culture medium increased. These results suggest that the combined use of these two vitamins might be of interest in postsurgical therapy and in wound healing.
