- Centella / gotu kola aids wound healing by boosting collagen and fibronectin production in collagen cells / fibroblasts

- Abstract: The mechanism of action of the total triterpenoid fraction extracted from Centella Asiatica (TTFCA) was evaluated using human skin fibroblast cultures as the experimental system. In particular its influence on the biosynthesis of collagen, fibronectin and proteoglycans was considered. The presence of TTFCA (25 micrograms/ml) does not seem to affect cell proliferation, total protein synthesis or the biosynthesis of proteoglycans in a significant way. A statistically important increase was observed in the percentage of collagen and, as revealed by immunofluorescence measurements, in cell layer fibronectin. This effect on collagen and fibronectin may help to explain the action of TTFCA in promoting wound healing, and suggests an interesting working hypothesis for its action on basal endothelia.
