Adiposed-derived stem cell (ADSC) have relative advantages in accessibility (less invasif), abundance stem cell compared to other kinds of stem cell and easier to get adipose in large quantities than bone marrow. In this Study, we investigated whether subcutaneous injection of ADSC significantly increase collagen synthesis, epidermis and dermis thickness, colagen density, and microvascular density in Photoaging Balb/C mice. We use 27 mice, divided by 3 group. The first group (A) were given UVB light irradiation and stem cell. The B group were given UVB light irradiation and placebo (NaCl 0.9%). The C group as the control group was untreated (no UVB light irradiation and no stem cells).The results showed that 1x104 ADSC subcutaneuous injection significantly increase collagen synthesis in Balb/C mice and collagen density in photoaging. In conclusions revealed that Adiposed-derived Mesenchymal stem cells stimulate colagen density, and improved photoaging.
