The Effect of Mesenchymal Stem Cells Derived-Conditioned Media in Combination with Oral Anti-Androgenic Drugs on Male Pattern Baldness: An Animal Study.

OBJECTIVE

Androgenetic alopecia (AGA) is a prevalent form of hair loss, mainly caused by follicular sensitivity to androgens. Despite developing different anti-androgen treatment options, the success rate of these treatments has been limited. Using animal models, this study evaluated the therapeutic effects of umbilical cord (UC) stem cell conditioned media (CM) combined with oral anti-androgens for hair regeneration.

MATERIALS AND

METHODS

In this experimental study, Poloxamer 407 (P407) was used as a drug carrier for subcutaneous testosterone injection. AGA models were treated with oral finasteride, oral flutamide, and CM injections. Samples were thoroughly evaluated and compared using histological, stereological, and molecular analyses.

RESULTS

Injecting CM-loaded hydrogel alone or combined with oral intake of anti-androgens improved hair regeneration. These treatments could promote hair growth by inducing hair follicles in the anagen stage and shortening the telogen and catagen phases. Furthermore, the combination treatment led to an upregulation of hair induction gene expression with a downregulation of inflammation genes.

CONCLUSION

Through a reduction in inflammation, injection of CM-loaded hydrogel alone or combined with oral intake of anti-androgens induces the hair cell cycle with regeneration in damaged follicles. Hence, this could be a promising therapeutic method for AGA patients.
