    TLDR Mesenchymal stem cell therapy may help treat alopecia areata by promoting hair growth and reducing inflammation.
    The document from 2018 reports on a study that explored the potential of mesenchymal stem cell therapy (MSCT) for treating alopecia areata (AA). The study used in vitro models, including human dermal papilla cells (hDPCs) treated with interferon gamma (IFN-γ) to simulate an AA-like condition. The findings indicated that MSCT could improve the viability of hDPCs, stimulate hair growth-related signaling pathways (Wnt/β-catenin and JAK/STAT), and increase the expression of growth factors. Additionally, MSCT showed immunomodulatory effects that might help restore the immune privilege of hair follicles. Despite these promising results, the study's sample size was very small (n=2), which means the conclusions need to be confirmed with larger-scale research. The study suggests that MSCT has the potential to be a new treatment for AA by promoting the transition to the hair growth phase and reducing inflammation, but further investigation is necessary to fully understand its therapeutic mechanisms.

      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.
