Scientists identify key mechanism controlling skin regeneration Date: August 3, 2022 Source: Northwestern University Summary: The outer layer of skin, the epidermis, is constantly turning over to replace dead or damaged cells throughout our lifetime. Skin stem cells need to continuously make decisions: either make more copies of themselves (self-renewal) or switch their fate towards differentiation. The molecular mechanisms controlling this process remain poorly understood. Now a research team has identified a molecular switch that plays an early and critical role in the skin stem cell differentiation process. Story Source: Materials provided by Northwestern University.
