Treatment of MSCs with Wnt1a-conditioned medium activates DP cells and promotes hair follicle regrowth
June 2014
in “Scientific Reports”
TLDR Wnt1a-conditioned medium from stem cells helps activate cells important for hair growth and can promote hair regrowth.
The study from June 25, 2014, explored the potential of Wnt1a-conditioned medium (Wnt-CM) from bone marrow mesenchymal stem cells (BM-MSCs) to promote hair follicle regeneration. The treatment with Wnt-CM was found to accelerate the transition of hair follicles to the growth phase and increase the expression of hair induction-related genes and alkaline phosphatase (ALP) in dermal papilla (DP) cells in mice. Additionally, Wnt-CM was able to restore hair growth gene expression that had been downregulated by dihydrotestosterone (DHT) treatment. The study also showed that Wnt-CM enhanced DP cell migration, which is crucial for hair follicle development. These findings suggest that Wnt1a overexpression by BM-MSCs could be a potential therapeutic strategy for treating alopecia. The study included experiments on human DP cells and a hair regeneration model in mice, with experiments repeated three times and results showing statistical significance at P < 0.05. However, the exact number of mice or human participants was not mentioned in the summary.
