    TLDR Host cells are crucial for the maturation of reconstructed hair follicles.
    In 2017, a study was conducted to understand the role of host cells in hair follicle reconstruction. The researchers encapsulated dermal and epidermal cells in semi-permeable capsules and observed their behavior both in vitro and in vivo. In vitro, the cells formed spheroids but did not differentiate into hair follicles. When transplanted into mice, the encapsulated cells formed structures similar to immature hair follicles but did not mature into full hair follicles. However, when the spheroids were removed from the capsules and transplanted into mice, about 70%-80% developed into mature hair follicles. The study concluded that host cells play a vital role in the maturation of reconstructed hair follicles, suggesting that the interaction between host and transplanted cells is crucial for hair follicle reconstruction.

      community Verteporfin and Microneedling

      in Treatments 6 months 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.

      community Hair follicle cloning is already possible

      in Chat  38 upvotes 2 months ago
      Hair follicle cloning is claimed to be possible but not widely available due to potential safety issues, such as cancer risks. Current treatments like finasteride and dutasteride are not effective for everyone, and there is frustration over limited access to these medications.
