Stem Cells Can Be Directed To Become Specific Cells That Can Be Used In Humans to Regenerate and Rep

Stem Cells are undifferentiated or partially differentiated cells that can differentiate into different types of cells and multiply indefinitely to produce more of the same stem cell in multicellular organisms. They are the ancestor of all cell types in a lineage. Although they are present in both embryonic and adult organisms, they differ slightly in each. They are typically distinguished from precursor or blast cells, which are typically committed to differentiating into one cell type, and progenitor cells, which cannot divide indefinitely.
