    TLDR Human induced pluripotent stem cells can be used to create cells that help grow hair.
    The study explored the potential of using human induced pluripotent stem cells (hiPSCs) to generate mesenchymal stem cells (MSCs) enriched for the CD271+CD90+ subpopulation, which are crucial for dermal papilla (DP) cell regeneration in hair follicle (HF) bioengineering. The researchers successfully cultured hiPSCs in MSC medium, resulting in cells that expressed MSC markers and could differentiate into various cell types. Notably, 10-25% of these hiPSC-MSCs were CD271+CD90+, a significantly higher rate compared to bone marrow-derived MSCs. These cells intrinsically expressed DP marker genes and, when treated with specific growth factors, exhibited DP cell-like morphology and maintained or up-regulated DP biomarkers. The induced cells responded to minoxidil and, when combined with human keratinocytes and fibroblasts, formed hair follicle-like structures in SCID mice. This study highlighted the potential of hiPSCs in generating DP equivalents, which could aid in drug discovery for hair diseases and the regeneration of human HFs.

      community Has anyone tried Exosomes from Musely or somewhere else?

      in Hair Systems  9 upvotes 7 months ago
      Exosomes from Musely are being discussed as a topical hair loss treatment containing ingredients like latanoprost, caffeine, cetirizine, melatonin, vitamin D3, vitamin E, and biotin. Users are curious about its effectiveness and potential side effects, noting it may take 4-6 months to see results.

      community Please explain this Minoxidil phenomena

      in Minoxidil  59 upvotes 2 years 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  140 upvotes 1 year 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.
