    TLDR Humans have limited regenerative abilities, but new evidence shows the adult brain and heart can regenerate, and future treatments may improve this by mimicking stem cell environments.
    The document from 2008 discusses tissue homeostasis and regeneration, noting that humans have limited regenerative abilities compared to simpler organisms, with certain tissues like the liver and bone capable of regeneration. It challenges previous beliefs that the adult human brain and heart cannot regenerate, presenting evidence of neurogenesis and cardiomyocyte division. The role of stem cell niches in maintaining tissue balance is emphasized, with these niches found in areas such as the intestine, hair follicle, and bone marrow. The document also touches on the potential of tissue engineering and regenerative medicine to enhance autologous tissue regeneration by understanding and replicating the microenvironments of stem cell niches. It suggests that future approaches may involve local implantation of substances or nanoconstructed niches to support natural cell migration and tissue repair.

      community A concise, easy-to-understand post on Androgenic Alopecia theory and its practical applications

      in Research/Science  92 upvotes 2 years ago
      The mechanism of Androgenic Alopecia and practical applications of treatments like Minoxidil, Finasteride, RU58841, dermarolling, scalp massages, anti-fungals, progesterone, estrogen, PPAR-γ activators, reducing oxidative stress, and scalp exercises. It explains why DHT is important in AA and how other factors might be involved such as hypoxia, increased DKK-1 expression, morphological changes to the scalp, skull growth during childhood/puberty, and blood flow.

      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.

      community New Treatments, and a Huge Group Buy with Lots of Research

      in Research/Science  109 upvotes 1 year ago
      A user is organizing a group buy for various compounds aimed at reversing hair loss and gray hair, and improving brain health and fat loss. The user has developed a treatment plan based on extensive research and is inviting others to participate, with the option to choose only the compounds they need.

      community Hair theory Scar tissue and Verteporfin

      in Chat  25 upvotes 5 months ago
      A user suggests that deeper microneedling with Verteporfin injections might help regrow hair in areas with scar tissue, alongside a DHT blocker. Another user explains that hair loss might be due to reduced Wnt/β-Catenin signaling and suggests that treatments like Minoxidil, Finasteride, and microneedling could potentially reverse it.
