Stem Cells and Development
Stem cells present in Human body are
unspecialized cells. They have the power to differentiate into any cell in an
organism and to regenerate. Stem cells exist both in embryos and adult cells.
They are specialized into many stages. Each stage reduces its developmental
potency, where its produces unipotent stem cell which can't differentiate into
as many different types of cells as a pluripotent cells.
