Influence of extract on umbilical cord cells and potential treating cutaneous wound.

This research aimed to test the effects of L. from Vietnam on fibroblasts and UC-derived mesenchymal stem cells (UC-MSCs) from human umbilical cord (UC) on the scratch assay. We tested the extract at different concentrations and then assessed the level of expression of the factors involved in the inflammatory process on fibroblasts including IL-33, VCAM, CD248 by assay real time qPCR. At the concentrations of 0.025 μL/mL and 0.03 μL/mL, the extracts positively affected fibroblast proliferation and UC-MSCs. By contrast, the concentration of 0.058 μL/mL, the extract was toxic to UC-MSCs and fibroblast cell lines, the cells were no longer able to survive. qPCR results show that L. extract has the ability to reduce the expression levels of IL-33 (50.8%), VCAM (32.1%), CD248 (46.13%) which trigger inflammatory processes, thereby reducing cellular stress and promoting the process of healing scratches. Our study revealed the proliferation capabilities of L. extract from Vietnam In vitro. Hence, L. could be recommended as a potential source of wound healing agents.
