In recent years, an increase in the demand for therapeutic strategies for improving quality of life has necessitated innovative approaches to designing intelligent biomaterials aimed at the regeneration of tissues and organs. These daughter cells become either new stem cells or specialized cells (differentiation) with a more specific function, such as blood cells, brain cells, heart muscle cells or bone cells. Steroids may be given as an injection. Contact Us, Hours Stable cells can also respond and regenerate but to a lesser degree and are quite dependent on the supporting stromal framework.
