Corneal Endothelial Cell Fate Is Maintained by LGR5 Through the Regulation of Hedgehog and Wnt Pathways

A potential non-invasive topical treatment targeting the WNT Signaling Pathway for hair regeneration is being researched, with positive results on human hair follicle cells. Current effective treatments for hair loss include Minoxidil, finasteride, and hair transplantation.

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.

Verteporfin followed by retinoic acid improves wound regeneration in mini-pigs. Retinoic acid does not significantly enhance regeneration in rabbits.

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.

Exosomes from mesenchymal stem cells can increase hair growth by enhancing anagen duration and hair shaft thickness through the Wnt/beta-catenin pathway. Phase 2 trials show improved hair counts over 24 weeks.

A new treatment using dermal sheath cup cells may regrow hair and could require repeat treatments every 8 years. Users discuss ongoing trials and plan to use finasteride and minoxidil until the treatment is available.
