AGA Biocellular Stem/Stromal Hair Regenerative Study

Detailed Description:

The cosmetic discipline of hair restoration is rooted in numerous landmark studies and progressive medical science in the medical literature. , , , , With the advent of advance theories and science within the scope of regenerative medicine, numerous reports are noted in the literature. , , , , , using biological modalities, e.g., HD-PRP concentrates defined as \> 4-6 times patient circulating baselines, for stimulation of scalp tissues and hair follicles in androgenetic alopecic (AGA).

Design of this study is intended to be a prospective, randomized, multicenter trial with blinding of outcomes for independent observer, clinical provider and patient observation/satisfaction studies. The study proposes adipose-derived (AD) biocellular material when mixed with platelet high density concentrates (HD-PRP) offers a potential advantage for a markedly more effective therapeutic profile in areas of follicular miniaturization, tissue age related senescence, and effect the decreased vascular capabilities by stimulation of vasculoneogenesis. The benefits of using autologous adipose-derived stem/stromal cell (ADSCs) populations are cell proliferation and vasculogenesis that is intrinsically linked with native immunomodulatory capacities. Reports describing the safety and efficacy of this biocellular combination have been reported in peer reviewed literature. , In the second and third arm of this study, the use of regenerative protocols currently being utilized in the treatment of degenerative musculoskeletal conditions is employed. These protocols feature the use of an emulsified AD-tSVF and emulsified cell enriched AD-cSVF containing the full heterogeneous stem/stromal cell population and matrix that is injected into the regions of scalp containing the microenvironment (niche) of the hair follicle. In Arm 3, cellular enrichment of the emulsified AD-tSVF is accomplished via a semi-automated, closed sterile system (Healeon CentriCyte 1000 system) to isolate and concentrate AD-cSVF. The AD-cSVF is then mixed with high-density platelet rich plasma (HD-PRP) concentrates and emulsified AD-tSVF tissues (AD-tSVF) prior to scalp injection. This injected cell-enriched product contains native adipose tissue scaffolding, autologous HD-PRP, and enriched adipose stem/stromal cell-enriched concentration of stromal/stem cells (AD-cSVF).

The goal of this study is to demonstrate the safety and efficacy of the HD-PRP + AD-tSVF + AD-cSVF biocellular injections into the scalp of men and women with a diagnosis of non-scaring alopecias, with full reporting of AE and SAE (adverse events). The biocellular material is injected 3-5 mm in depth within the mid-reticular dermis to upper subcutaneous fat layer of the scalp for the purpose of regenerating the miniaturized hair follicle, and delivering a milieu of stromal/stem cells that facilitate regenerative changes within the tissue sites. In addition to providing tissue scaffolding, and a greater number of stromal/stem cells to the tissues surrounding the follicular niche, the novel use and emulsification of AD tissues with cell-enriched biocellular material permits ergonomic facilitation of layered injection patterns in the scalp with small gauge (25-27 gauge) needles This emulsified AD Biocellular methodology reduces injection pressure requirements using smaller gauge needles. When clinically compared to the use of much larger needles required to inject non-emulsified AD-tSVF, it is an improvement on current techniques.
