    TLDR Different materials affect the growth of brain cells and fibroblasts, with matrigel being best for brain cell growth.
    The study from five years ago assessed the growth and differentiation of pyramidal neural precursors (PNPs), neural stem cells (NSCs), and fibroblasts on different biomaterials, including fibrin, collagen, hyaluronic acid (HA), sciatic nerves, and matrigel. The findings indicated that PNPs struggled to attach and grow on most materials except for matrigel, which supported three-dimensional neurite growth. NSCs showed directional neurite growth on aligned fibrin, which however degraded within two days. Induced NSCs (iNSCs) survived and differentiated on aligned collagen-poly(lactic-co-glycolic acid) (PLGA) for at least two weeks, but without aligned neurite extension. Fibroblasts generally exhibited better growth than neural cells on the materials, with directional growth on aligned fibrin and scattered growth on alveolate collagen. This study provided valuable information for optimizing biomaterials to culture specific cell types for cell therapy applications.

      Biotin is being misleadingly marketed as a primary treatment for androgenic alopecia, overshadowing more effective treatments like finasteride and minoxidil. There is a call for increased awareness and accountability to prevent misinformation.

      The conclusion of this conversation is that the user "DuckSeasonCamelSeasn" found that consuming grapefruit juice prior to taking finasteride or dutasteride helped them become a responder to the medications and regain hair growth. However, there are warnings about potential risks and interactions with other medications, so caution should be exercised.

      The user has been using finasteride (2mg daily) to halt hair loss and is considering dermarolling with essential oils (Rosemary, Thyme, Peppermint, Tea Tree, Lavender, Jojoba) to restore the hairline. They are hesitant to use Minoxidil due to concerns about losing gains if they stop.
