Document Summary
Cells: organized into tissues, organs, & systems. Tissues: organized groups of diff. cell types that work together to carry out a particular function, each tissue has its own turnover time. Stem cells: relatively unspecialized (immature) cells that can divide & differentiate into specialized cell types, can be used therapeutically to engineer or regenerate tissues & organs. Stem cells in tissues have regenerative properties. Adult stem cells: aka somatic stem cells, found in mature tissues, help maintain & regenerate tissues, multipotent: Cell capable of differentiating into a limited # of diff. cell types in body. Embryonic stem cells: make up early embryos, pluripotent. Capable of differentiating into nearly any cell type in body: can be obtained from human or cloned embryos, may also be created by inducing adult cells to de-differentiate . Totipotent: describes a cell w/ the ability to differentiate into any cell type in the body.
