stem cell niche

A stem cell niche is the specialized environment within the body where stem cells reside. It includes surrounding cells, molecules, and physical conditions that help maintain stem cell properties like self-renewal and the ability to become other cell types. The niche provides essential signals and support, ensuring stem cells function properly for tissue growth, repair, and regeneration. Think of it as a specialized "home" that nurtures stem cells and controls when and how they divide or differentiate into different cells needed by the body.
