    TLDR Stem cell niches are adaptable and key for tissue maintenance and repair.
    The document reviewed the adaptive response of stem cell niches to systemic signals, aging, and local perturbations, emphasizing their role in tissue homeostasis and repair. It discussed the components of niches, such as support cells and the extracellular matrix, and their interaction with stem cells to regulate behavior, as well as the impact of aging on niche activity. The review suggested that manipulating stem cells and their microenvironments could rejuvenate aged stem cells and enhance regenerative therapies. It also highlighted the importance of dormant stem cells in tissue regeneration and the adaptability of stem cell niches to environmental changes, such as dietary fluctuations in Drosophila. The document concluded that the plasticity of stem cell niches is crucial for integrating systemic and local signals to maintain tissue homeostasis, but many questions about stem cell behavior and niche response to damage remain unanswered. The work was supported by Spanish research funding bodies and declared no competing financial interests.

      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.

      community Diffuse hair loss and scalp biopsies

      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 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.
