    TLDR Hair follicle transplantation speeds up wound healing in diabetic mice.
    This study demonstrates that hair follicle (HF) transplantation significantly accelerates wound healing in diabetic mice by promoting re-epithelialization, wound contraction, angiogenesis, and collagen deposition while reducing inflammation. Conducted on 36 male C57BL/6 mice, the research found that HF transplantation improved healing rates in both normoglycemic and hyperglycemic conditions, with diabetic wounds healing up to 98.46% by day 10 post-transplantation. The transplantation process enhances cellular proliferation, increases microvessel density, and reduces inflammatory cytokines, suggesting an immunomodulatory role of mesenchymal stem cells within HFs. Despite the challenges of hyperglycemia, HF transplantation remains a promising therapeutic strategy for diabetic wounds, although further research is needed to explore long-term effects and clinical feasibility.

      community Verteporfin and Microneedling

      by nkrata in Treatments 1 year ago
      Clinical studies by Dr. Barghouthi and Dr. Bloxham indicate that Verteporfin, when used with FUE and FUT hair transplantation methods, shows promise in hair follicle regeneration and minimal scarring due to its ability to inhibit Yes-associated protein (YAP). Microneedling at depths of 3-3.5mm, combined with Verteporfin, could potentially reactivate dormant follicles, although the optimal dosage and application method are still under investigation. Concerns remain about the DHT sensitivity of regenerated follicles, highlighting the need for further research to optimize trauma levels and Verteporfin concentrations to achieve effective and scar-free hair regeneration.
