    TLDR Tissue from dog stem cells helped grow hair in mice.
    The 2016 study explored the potential of dermal papilla-like tissues (DPLTs) derived from canine adipose-derived mesenchymal stem cells (ASCs) to promote hair growth in athymic nude mice. Thirty mice were divided into control and treatment groups, with the latter receiving DPLTs injections into skin wounds. The DPLTs were found to closely resemble natural dermal papillae in structure and protein expression, including the expression of versican and alkaline phosphatase (ALP). The treatment group exhibited significant hair follicle and sebaceous gland regeneration, as well as increased vascularization, which was attributed to the secretion of vascular endothelial growth factor (VEGF) by the DPLTs. Although the DPLTs did not integrate into the new dermal papillae, their paracrine effects were deemed responsible for the observed hair regeneration. This suggests that engineered canine DPLTs could be a viable treatment for alopecia, providing a basis for further research into hair follicle 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.

      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.
