Background: Adipose-derived stem cells (ADSCs) are mesenchymal stem cells (MSCs) within the stromal vascular fraction of subcutaneous adipose tissue. ADSCs secrete growth factors and other proteins, and have been used to regenerate skin with satisfactory results.

Objective: This review focuses on the effect of ADSCs and their secretory factors on the stimulation of hair growth in vitro, ex vivo and in vivo.

Results: The conditioned media of ADSCs (ADSC-CM) increases the proliferation rate of human follicular cells. ADSCs-derived proteins improve hair growth and protect human dermal papilla cells against cytotoxic injury caused by androgen and reactive oxygen species. Moreover, ADSC-CM induces the anagen phase and promotes hair growth in mice, and enhances the elongation of hair shafts in ex vivo human hair organ cultures.

Conclusion: ADSC-CM promotes hair growth in vitro, ex vivo, and in vivo. Given that ADSCs are one of the most accessible sources of MSCs, ADSC-derived proteins may be feasible clinical therapeutic agents for the treatment of hair loss.
