    TLDR Lab-made tissues from dog fat stem cells can help grow hair by releasing a growth factor.
    The study demonstrated that dermal papilla-like tissues (DPLTs) derived from canine adipose-derived mesenchymal stem cells (ASCs) could promote hair growth by forming structures similar to natural dermal papillae and secreting vascular endothelial growth factor (VEGF). The DPLTs were injected into skin wounds of thirty athymic nude mice, which were then observed for hair follicle formation, vascularization, and VEGF secretion at intervals of 10, 20, and 30 days. The results showed significant hair follicle regeneration and increased angiogenesis in the DPLTs group compared to the control group, particularly at days 10 and 20 post-injection. By day 30, the differences were not significant. The study concluded that DPLTs have the potential to serve as an alternative therapy for hair regeneration, particularly in alopecic animals, by enhancing hair follicle regeneration and neovascularization. However, the study acknowledged limitations and called for further research to explore additional paracrine and signaling pathways involved in hair regeneration.

      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.

      The conversation is about using vitamin C and Magnesium L-Threonate for hair growth by reducing DHT binding to dermal papilla cells. The original post about vitamin C's pH levels and sebum control was possibly removed by a moderator.

      in Research  692 upvotes 3 months ago
      Scalp biopsies are crucial for diagnosing hair loss conditions like Diffuse Unpatterned Alopecia (DUPA) and retrograde hair loss, as treatments like finasteride and dutasteride may not be effective if other conditions are present. Combining PPAR-GAMMA agonists with retinoids could improve treatments for conditions like Lichen Planopilaris.
