What? Where? How? Why?

4. Types of Stem Cells Embryonic stem cells Adult stem cells
Inner cell mass (~30 cells) of the blastocyst (~150 cells)
First 3-4 days after fertilization
Pluripotent - Can form all tissue types & organs
Adult stem cells
Small populations retained in various tissues & organs
Unipotent – can form only 1 cell type
Multipotent – can form into a limited # of differentiated cell types
Induced pluripotent stem cells
Retrieved from adult differentiated cells
Genetically reprogrammed to mimic embryonic stem cells
