    TLDR Scientists developed a method to grow human fetal skin and digits in a lab for 3-4 weeks, which could help study skin features and understand genetic interactions in tissue formation.
    In 1997, researchers Zeltinger and Holbrook developed a suspension organ culture (SOC) system to study human fetal skin in vitro. They used this system to culture fetal digits and skin samples for 3 to 4 weeks, finding optimal conditions to be DMEM-F12 medium in a serum-free environment with a 45% oxygen atmosphere. The system supported the development of the epidermis, dermis, hair follicles, nails, and glands of the skin samples. The study involved 28 digit SOCs and 102 skin biopsies, with 36 of the skin SOCs developing hair follicles. The researchers concluded that this SOC system could be a valuable tool for studying various features of skin and for investigating the genetic mechanisms involved in tissue interactions and appendage formation.

      Users discuss alternatives to DHT blockers for hair loss, suggesting minoxidil, microneedling, natural DHT blockers, and scalp massages. Some explore RU58841, ketoconazole, hair transplants, and hair systems due to side effects from finasteride and dutasteride.

      community The urge to buy Clascoterone 5% solution

      in Research/Science  11 upvotes 3 weeks ago
      Clascoterone 5% solution is not yet commercially available, with only the 1% solution currently sold for acne. Users discuss the potential of Clascoterone as a hair loss treatment, comparing it to other anti-androgens like RU58841 and Eucapil.
