Keratin Biomaterials Activate Schwann Cells via Integrin-Mediated Signaling and Promote Regeneration of Large Peripheral Nerve Defects in a Rabbit Model

Fatty acid metabolic signaling can activate epithelial stem cells for hair regeneration. Oleic and palmitoleic acids showed the best results, but practical application on humans remains uncertain.

ABS-201 may block prolactin receptors in hair, potentially reducing androgen receptors and affecting hair loss. It could also aid collagen synthesis and stem cell pathways, similar to GHK-Cu.

MCL-1 protein may help maintain hair follicles in the growth phase and prevent miniaturization. There is interest in experimental treatments like exosomes, peptides, or stem cell serums to upregulate MCL-1 for hair loss, especially for those not using minoxidil or finasteride.

IGFBP‐rP1 shows potential for treating androgenic alopecia by influencing hair cycle transitions. Increasing IGF-1 levels may have similar effects to Minoxidil and 5-AR inhibitors in reducing hair loss.

Fibrin-based hydrogels support stem cells for hair follicle regeneration, showing promise for treating alopecia and wound healing. They enhance cell viability, maintain stemness, and promote hair and tissue regeneration without teratoma formation.
