Faculty Opinions Recommendation of Application of Mesenchymal Stem Cells Derived from Bone Marrow and Umbilical Cord in Human Hair Multiplication

    TLDR Mesenchymal stem cells from bone marrow and umbilical cord can help regenerate hair follicles.
    The study by Yoo BY et al. explored the use of mesenchymal stem cells (MSCs) derived from human bone marrow and umbilical cord to generate dermal papilla-like structures for hair follicle regeneration. These structures, termed dermal papilla-like tissues (DPLTs), were shown to express specific markers and interact with keratinocytes to form hair bulb-like structures. When implanted into immunodeficient mice, DPLTs demonstrated the capacity to induce hair follicles, although they were not detectable at the induction sites after a prolonged period, likely due to apoptosis. The study provided supportive evidence for the potential of MSCs as an alternative source for hair inductive components in hair follicle regeneration, despite the challenges in maintaining DPLTs long-term.

      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.
