Study of Constructing Tissue Engineered Urethra Membrane Using Hair Follicle Stem Cells and Nano Silk Fiber In Vitro

    TLDR Rabbit hair follicle stem cells and nano silk fibers can create a tissue-engineered urethra.
    The study explored the feasibility of constructing a tissue-engineered urethra membrane using rabbit hair follicle stem cells and nano silk fibers. Hair follicle stem cells were isolated, cultured, and then seeded on electro-spun nano silk fibers. The results showed that the stem cells had a high amplification factor and colony forming rate, with significant expression of K19, p63, and CD29 markers. When seeded on nano silk fibers, the stem cells formed a stratified epithelium-like structure, confirmed by positive AE1/AE3 staining. The study concluded that combining rabbit hair follicle stem cells with nano silk fibers successfully constructed a tissue-engineered urethra, suggesting potential for future in vivo repair studies.

      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.

      The post and conversation are about the role of the enzyme 3alpha-hydroxysteroid reductase in hair loss and the potential of compounds like procyanidin B2 and sulforaphane to boost its activity for hair regrowth. Further research is needed to develop effective treatments based on this theory.

      Microneedling with needle lengths of 1.5mm to 2.5mm to stimulate hair follicle stem cells for potential hair growth. Using needles longer than 2.5mm is not recommended due to risk of puncturing veins in the scalp. A dermastamp is suggested over a roller.

      TDM-105795 showed promising hair growth results, with higher efficacy than placebo and minimal side effects. It activates dormant hair follicle stem cells and may maintain gains without immediate loss, unlike minoxidil.
