Cellular therapy with human autologous adipose-derived adult cells of stromal vascular fraction for alopecia areata
Abstract
Background: Most common forms of hair loss (alopecia) are caused by aberrant hair follicle cycling and changes in hair follicle morphology. However, current treatments for alopecia do not specifically target these processes. Adipose-derived stromal vascular cells (ADSVCs) that can be harvested from fat cells are one of the latest breakthroughs in the aesthetic field. The potential use of stem cell-based therapies (SCBT) for the repair and regeneration of various tissues and organs offers a paradigm shift that may provide alternative therapeutic solutions, which can be applied to prevent hair loss. This study aimed to present clinical cases of SCBT for the treatment of alopecia areata by transplantation of ADSVCs in the scalp.
Methods: Twenty patients (9 women and 11 men) were recruited to our retrospectively registered study. After lipoaspiration, autologous ADSVCs were generated and characterized before the injection of 4-4.7 × 106 cells into the scalp of the patient. Hair regeneration was assessed by three clinical tests: the pull test, hair quality, and hair density.
Results: All patients experienced hair regeneration, increased hair growth and decreased pull test 3 and 6 months after the treatment with ADSVCs [hair density (85.1 ± 8.7 vs 121.1 ± 12.5 hair/cm2, P < 0.0001), hair diameter (60.5 ± 1.8 vs 80.8 ± 2.4μ, P < 0.0001) and pull-test values (4.4 ± 0.3 vs 0.8 ± 0.2, P < 0.0001), untreated versus 6 months post-operative)]. Significant variation was observed between men and women only for hair diameter. No significant differences were observed with age.
Conclusions: The obtained results prove the efficacy and the safety of the treatment, and satisfaction of the patients confirm the quality of the results.

Conflict of interest statement
Ethics approval and consent to participate
The study was conducted in strict adherence to the tenets of the Declaration of Helsinki, and it was retrospectively registered in ClinicalTrials.gov (Identifier: NCT03427905). The protocol was approved by the institutional review board of REVIVA Regenerative Medicine Center at the Middle East Institute of Health University Hospital as previously [27, 28] under the academic regulations of the public institution, the Lebanese University. All patients provided written informed consent and fresh samples were procured by Dr. Rami Andari (plastic surgeon) from REVIVA at the Middle East Institute of Health (MEIH) University Hospital. The first patient was enrolled in March 2013.
