    TLDR Newly found stem cells in horse hooves show promise for treating a hoof disease called laminitis.
    This study explores a newly identified population of stem progenitor cells (HPCs) from the coronary corium of equine feet, which could be pivotal in treating laminitis in horses. These HPCs express markers typical of mesenchymal stem cells and demonstrate the ability to expand, differentiate into multiple lineages, and potentially regenerate dermal/epidermal and vascular tissues. The cells also show immunomodulatory functions and are highly proliferative. The research, which involved post-mortem samples from 6 foals, indicates that HPCs have a higher expression of certain keratins compared to adipose-derived stem progenitor cells, suggesting a stronger potential for skin regeneration. Despite limitations due to COVID-19 affecting sample availability, the study concludes that HPCs, with their pro-vasculogenic and immunosuppressive properties, offer a promising target for developing new cell-based therapies for laminitis in horses.

      community A concise, easy-to-understand post on Androgenic Alopecia theory and its practical applications

      in Research/Science  92 upvotes 2 years ago
      The mechanism of Androgenic Alopecia and practical applications of treatments like Minoxidil, Finasteride, RU58841, dermarolling, scalp massages, anti-fungals, progesterone, estrogen, PPAR-γ activators, reducing oxidative stress, and scalp exercises. It explains why DHT is important in AA and how other factors might be involved such as hypoxia, increased DKK-1 expression, morphological changes to the scalp, skull growth during childhood/puberty, and blood flow.

      A user suggests that deeper microneedling with Verteporfin injections might help regrow hair in areas with scar tissue, alongside a DHT blocker. Another user explains that hair loss might be due to reduced Wnt/β-Catenin signaling and suggests that treatments like Minoxidil, Finasteride, and microneedling could potentially reverse it.

      Hair loss treatments discussed include Dutasteride with Ketoconazole, tissue engineering strategies, and androgenetic alopecia therapies. Massage doubles follicular retention, improving treatment effectiveness.

      community Minoxidil can prevent hair follicle miniaturization!?

      in Minoxidil  6 upvotes 3 years ago
      Minoxidil can prevent hair follicle miniaturization, not just stimulate hair growth. Finasteride and dutasteride don't work for everyone, suggesting DHT may not be the sole cause of hair loss; hair loss could be due to multiple factors, including autoimmune conditions.
