    TLDR The technique can isolate cells to help treat skin pigmentation issues.
    The study explored the isolation of melanocyte stem cells (MelSCs) from human hair follicles using the "side population" technique, which is commonly applied to hematopoietic and tumor stem cells. The researchers analyzed mRNA expression and melanosome structure, confirming that the isolated SP-fraction contained MelSCs along with differentiated melanocytes. These cells were then used to create a cell-chitosan/gelatin composite, which successfully repopulated the skin of immunocompromised mice, leading to regained pigmentation. This indicated that the SP technique could effectively isolate MelSCs for potential use in treating pigmentary disorders.

      community Is there any new drug that looks promising ?

      in Research/Science  24 upvotes 1 year ago
      The conversation discusses GT20029, a drug in Phase II trials that targets androgen receptors with minimal systemic effects, and TDM-105795, a growth stimulant with a different mechanism than minoxidil that may revive papilla stem cells. Both are potential new treatments for hair loss.

      community Great news recently for people with hairloss!

      A potential treatment for alopecia involving a protein that calms hair follicles has shown promise in rats, but skepticism remains about its applicability to humans. Many users express doubt about the timeline for effective hair loss treatments, comparing it to past unfulfilled promises.

      community New Hair Loss Treatment: Adipose Derived Secretomes

      in Research/Science  18 upvotes 6 months ago
      Adipose-derived stem cell secretome showed significant improvement in hair density and growth, especially when combined with minoxidil, suggesting a synergistic effect. The study had limitations, including a small sample size and potential bias.
