Stem Cell Overview



Stem Cell Overview

Since their discovery in 1963, stem cells have been regarded as promising candidates for tissue engineering, organ regeneration, cell-based diagnosis and disease models. Stem cells in vivo are established in a "niche", and specific anatomical locations regulate how stem cells participate in the production, maintenance and repair of tissues. Niche is the basic unit of tissue physiology, integrating signals that regulate the balance response of stem cells and the body's needs. This kind of microenvironmental protection defends stem cells from physiological stimulation, and protects the host from the excessive proliferation of stem cells.
