    TLDR The new patch made of cell matrix and a polymer improves wound healing and supports blood vessel growth.
    The 2018 study explored a novel fibrous hybrid patch, combining human fibroblast-derived extracellular matrix (hFDM) with poly(L-lactide-co-caprolactone) (PLCL), for its potential in skin wound repair and endothelial cell delivery. The hFDM-PLCL patch was shown to significantly enhance human umbilical vein endothelial cells (HUVECs) adhesion, proliferation, and vascular morphogenesis in vitro, as well as attract human dermal fibroblasts (hDFB) in migration assays. In vivo, the patch improved wound healing in a mouse model, evidenced by faster wound closure, thinner epidermis, and signs of skin tissue regeneration, including hair follicle reappearance and increased neovascularization. The study concluded that the hFDM-PLCL patch provides a favorable microenvironment for cell-matrix interactions and has potential for use in tissue engineering and regenerative medicine. The number of people or animals involved in the study was not specified, but the number of samples used in various assays ranged from n=3 to n=4 for each group.

      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 5 years on Finasteride, 1.5 years on Minoxidil Foam

      in Progress Pictures  707 upvotes 9 months ago
      The user has been using finasteride for five years and minoxidil foam for 1.5 years to combat hair loss, experiencing significant regrowth after an initial shedding phase with minoxidil. They shared progress pictures and discussed treatment experiences, including the addition of minoxidil to their regimen after noticing reduced efficacy with finasteride alone.
