Glossary Epidermal Stem Cells

specialized cells in the skin that regenerate and repair tissue

Epidermal Stem Cells, also known as Skin Stem Cells, are specialized cells found in the outermost layer of the skin, the epidermis. These cells have the unique ability to self-renew and differentiate into various cell types that make up the epidermis, playing a crucial role in skin regeneration, wound healing, and maintaining the skin's barrier function.

in Update 415 upvotes 1 year ago

ET-02, a new hair loss treatment, shows promising results with a 6-fold increase in hair count, potentially outperforming minoxidil by activating stem cells in hair follicles. Further trials are ongoing to confirm its efficacy and safety, with potential market release in the future.

community Tazarotene shows strong standalone hair regrowth potential, not just a Minoxidil enhancer. Backed by VEGF, HF regeneration, and angiogenesis pathways. Here’s why.

135 upvotes 1 year ago

Tazarotene shows potential as a standalone treatment for hair regrowth by stimulating new hair follicle formation and promoting angiogenesis, similar to microneedling effects. It can be used topically without minoxidil, but users should start with a low concentration to avoid irritation.

community Keratin microspheres - breakthrough

14 upvotes 2 years ago

A gel of keratin microspheres promotes hair follicle growth, showing similar effectiveness to minoxidil in mice. The treatment activates hair growth pathways and reduces inflammation, with potential applications in drug delivery for hair-related disorders.
