Significant improvement in skin tone was reported after topical application of a facial cream (CALECIM® Professional Multi-Action Cream, CALECIM Cosmeceuticals, Singapore) containing conditioned media (CM) derived from Red Deer Umbilical Cord Lining Mesenchymal Stem Cell (RD-CLMSC) culture. This study investigates the paracrine effects of RD-CLMSC-CM on human dermal fibroblasts (HDF) to understand how it may increase skin turgor and elasticity.
Skin aging is associated with lower levels of extracellular matrix components such as hyaluronic acid (HA) and elastin, resulting in poor skin turgor and elasticity. Histochemical staining followed by photocolorimetry demonstrated that RD-CLMSC-CM upregulated HDF expression of elastin by 56% and HA by 83% compared with DMEM/10% Fetal Calf Serum (FCS).
To further quantify the effects of CM, a proliferation assay was used to assess HDF response to RD-CLMSC-CM exposure. Exposure to RD-CLMSC-CM resulted in the highest increase in HDF proliferation over DMEM/10% FCS (113%) followed by Human (H)-CLMSC-CM (112%), then Human Foreskin Fibroblast (FSF)-CM (16%).
These experimental results demonstrate both the cross-species efficacy and lack of toxicity of RD-CLMSC-CM on HDF. These pre-clinical studies also suggest the clinical effects of RD-CLMSC-CM on skin turgor may be related to increased HA and elastin production by HDF, as well as enhanced proliferation.
