Are all the same aren’t they???

2. Stem Cell
Undifferentiated cells that give rise to other types of cells

3. Stem Cell Totipotent=gives rise to all the tissues
needed by the body as
well as the
placenta
Zygote

4. Stem Cells

5. Stem Cell Pluripotent=can give rise to all other types of cells
Embryonic stem cells-taken
from blastocyst stage
of embryos donated at
fertility clinic

6. Stem Cell
Multipotent=(Somatic Stem Cells) give rise to multiple cells needed in the tissue they come from (they are NOT pluripotent)
Adult stem cells
example:Hematopoietic (Blood stem cells-donor bone marrow)
