    Glossary In Vitro Models

    experimental systems studying biological processes outside living organisms

    In Vitro Models refer to experimental systems used to study biological processes outside of a living organism, typically in a controlled laboratory environment. These models often involve the use of cell cultures or tissue samples to investigate cellular behaviors, drug responses, or disease mechanisms, providing valuable insights without the ethical and practical complexities of in vivo (within a living organism) studies.

      community Looks like a real cure to the root of baldness (DHT-induced senescence) was proven earlier this year

       737 upvotes 3 years ago
      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.

       13 upvotes 3 years 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.
