Stem Cells and Peripheral Nerve Injury: Potential and Challenges

    January 2015 in “ Elsevier eBooks ”
    Justin Câmara, Christoph J. Griessenauer
    TLDR Stem cells show promise for nerve injury treatment, but more research is needed before human use.
    Peripheral nerve injury had significant societal and economic impacts, with autografting being the gold standard treatment despite its limitations. Various stem cells, including pluripotent stem cells, bone marrow mesenchymal cells, adipose-derived stem cells, skin-derived precursor cells, and hair follicle pluripotent stem cells, could be induced into Schwann cells or Schwann cell-like phenotypes. These cells, when used with artificial nerve graft conduits, improved recovery in animal models. However, questions about the survival, differentiation, and safety of these therapies remained, and no cell-based therapies had been translated to humans yet, though the potential for stem cell-based therapy was promising.

      community Please explain this Minoxidil phenomena

      in Minoxidil  60 upvotes 1 year ago
      The post discusses the difference in effects of Minoxidil (Min) on scalp and facial hair. The user questions why Min-induced hair growth on the scalp is temporary, while facial hair growth seems permanent, even after stopping Min. They propose theories, including different Min mechanisms on body and facial hair, the role of DHT, and the possibility of not achieving fully terminal hair. The responses include personal experiences and theories about Min's effects on hair growth.

      community Fats on your Head to Stop Hair Loss?

      in Research/Science  138 upvotes 9 months ago
      The conversation discusses the potential of long-chain unsaturated fatty acids, like oleic and linoleic acid, as an additional treatment for hair loss, which may inhibit the enzyme responsible for converting testosterone to DHT and promote hair growth. Users humorously suggest using oils topically and discuss other hair loss treatments, but the main focus is on the science behind fatty acids and their role in hair health.
