    TLDR Skin stem cells in hair follicles are important for touch sensation.
    The study conducted 5 years ago investigated the role of compartmentalized epidermal stem cells in the hair follicle in tactile sensory unit formation in mice. These stem cells, located in the follicle upper-bulge, express a unique set of extracellular matrix (ECM) and neurogenesis-related genes. They deposit an ECM protein called EGFL6 into the collar matrix, which is necessary for the proper patterning, touch responses, and αv integrin-enrichment of lanceolate complexes, the mechanosensory end organs. The study also found that EGFL6 mediates cell adhesion via αv integrins and is crucial for mechanotransduction, the process by which cells convert mechanical stimulus into electrical activity. Furthermore, the study discovered that the unique tissue architecture provided by epidermal stem cells is a major determinant of the formation, preservation, and function of lanceolate complexes in the hair follicle.

      Treatments for hair loss, including finasteride, dutasteride, minoxidil, ketoconazole, microneedling, and low level laser light therapy, which aim to reduce DHT production, increase cell absorption and blood flow, and stimulate epidermal stem cells. It also stresses the importance of patience when using these treatments.

      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.
