    TLDR Elaine Fuchs' research shows how skin stem cells maintain health, aid in healing, and are involved in cancer.
    In 2020, Elaine Fuchs received the Canada Gairdner International Award for her pioneering research on adult skin stem cells, particularly their roles in homeostasis, wound repair, inflammation, and cancer. Her work using mouse models has been instrumental in understanding the regulation of hair follicle stem cells (HFSCs), uncovering the significance of growth factors, transcription factors, and epigenetic mechanisms in HFSC maintenance and hair growth. Fuchs' lab also revealed that HFSCs are involved in wound healing by contributing to epidermal migration for wound closure and that epidermal stem cells possess an inflammatory memory that improves their response to subsequent injuries. Furthermore, her research has shed light on the molecular mechanisms of skin cancer and the impact of the microenvironment on cancer stem cells. Her contributions have significantly advanced stem cell biology and impacted various fields, including immunology, dermatology, and cancer biology.

      in Research/Science  28 upvotes 10 months ago
      TDM-105795 showed promising hair growth results, with higher efficacy than placebo and minimal side effects. It activates dormant hair follicle stem cells and may maintain gains without immediate loss, unlike minoxidil.

      community Best Microneedle Lengths To Stimulate Stem Cells

      in Microneedling  18 upvotes 1 year ago
      Microneedling with needle lengths of 1.5mm to 2.5mm to stimulate hair follicle stem cells for potential hair growth. Using needles longer than 2.5mm is not recommended due to risk of puncturing veins in the scalp. A dermastamp is suggested over a roller.

      in Research/Science  58 upvotes 7 months ago
      A user proposed genetically engineering scalp stem cells to stop androgen receptors from causing hair loss. Others discussed the feasibility, existing research, and potential issues with this approach, including targeting the correct cells and unintended effects.
