Human Mesenchymal Stem Cell-Derived Conditioned Media for Hair Regeneration Applications.

Hair loss can have major psychological impact on affected population belonging to varied ethnic background. Hair is a mini organ in itself and serves many distinguishing functions ranging from maintaining body temperature to promoting social interactions. Major cause of hair loss is androgenic alopecia. Hair follicles possess receptor for androgen. However, DHT (Dihydrotestosterone) in excess results into shrinkage of hair follicle affecting hair growth adversely. The present review is focused on etiology of hair loss, traditional treatment approach and their limitations with side effects with special emphasis on unique properties of stem cells, favourable growth factors secreted by stem cells and strategies to enhance favourable growth factor/cytokine production for hair loss therapeutics. We discussed in details the present available treatment options for hair loss like drugs (Finasteride and Minoxidil), follicular hair transplant, laser therapy and serum therapy. These treatment options have their own disadvantages and side effects with appropriate alerts from regulatory authorities. The side effects of these modalities cannot be ignored and demands alternate therapy approach with less or no side effects. We feel that the stem cell therapy is advancing and is a promising modality in near future owing to its advantages and promising outcomes. This review article discusses possible stem cell therapy for hair regrowth and its advantages. We focused on use of conditioned media derived from stem cells instead of using stem cells directly for the therapy.
