    TLDR Alginate spheres help maintain hair growth potential in human cells for hair loss treatment.
    In the 2018 study, researchers explored the cultivation of human dermal papilla cells (DPCs) in alginate spheres as a method to maintain their hair growth-inducing potential for treating androgenic alopecia. The study found that DPCs did not proliferate within the alginate spheres but remained dormant and maintained their numbers. The dormant DPCs in the spheres showed upregulated expression of signature genes associated with DPCs and retained their proliferative capacity. The study concluded that the alginate sphere environment preserves the trichogenicity of DPCs, which could be beneficial for long-term cultivation and potential clinical applications in hair loss therapies. The study also noted that the size and density of the alginate spheres influenced cell survival and proliferation, with a convergence of live cell numbers after 70 days. The findings suggest that the 3D alginate sphere culture system can maintain the inductive properties of DPCs, which are essential for hair follicle formation and growth.

      A study that outlines the full model for androgenic alopecia (AGA) which links DHT to cellular senescence in dermal papilla cells, and suggests black chokeberry as a source of cyanidin 3-O-arabinoside polyphenol with potential anti-oxidant properties that could reverse this process. The post encourages reaching out to experts in anti-aging and longevity to research treatments involving the polyphenol.

      in Research/Science  14 upvotes 1 year ago
      He Shou Wu (Fo Ti) extract was found to prolong the hair growth phase, inhibit 5-alpha-reductase (like finasteride), reduce androgen receptors, and increase growth factors, potentially outperforming minoxidil in recovering hair follicle size after DHT exposure. Two compounds, emodin and TSG, are identified as responsible for these effects and warrant further investigation.
