Abstract (original English)

Objective Adipose-derived stem cells secrete various growth factors that promote hair growth. This study examined the effects of adipose-derived stem cell-conditioned medium on alopecia. Methods Adipose-derived stem cell-conditioned medium was intradermally injected in 22 patients (11 men and 11 women) with alopecia. Patients received treatment every 3 to 5 weeks for a total of 6 sessions. Hair numbers were counted using trichograms before and after treatment. A half-side comparison study was also performed in 10 patients (8 men and 2 women). Results Hair numbers were significantly increased after treatment in both male (including those without finasteride administration) and female patients. In the half-side comparison study, the increase in hair numbers was significantly higher on the treatment side than on the placebo side. Conclusion Treatment using adipose-derived stem cell-conditioned medium appears highly effective for alopecia and may represent a new therapy for hair regeneration.
