There are 2 type of stem cells
* embryonic stem cells
* and adult stem cells
fetal stem cells are grouped into the adult stem cell category
"Stem cell research has been around for almost as long as microscopes. Though it is only within the 1980s that more sophisticated genetechnology developments have allowed for the culturing (growing of cells) in laboratories. Fetal nerve cells were one of the first 'stem cells" not real stem cells though were used to treat Parkinson." source: Lasker Foundation
There are five basic stem cells classifications there is embryonic stem cells, fetal stem cells. There are the Umbilical cord stem cells, placenta stem cells, and lastly there are adult stem cells.
The use of stem cells is not unethical in and of itself, the ethics component revolves around the source of the stem cells and the concern that fetuses will be produced and intentionally destroyed in order to obtain stem cells.
C) stem cells preserved from the umbilical cord of the person
Embryonic stem cells have proved to be a safe source for the generation of human gametes in vitro.
well they are stem cells at the end of things

Yes, during pregnancy, fetal stem cells from the baby can cross the placenta and enter the mother's bloodstream. This phenomenon is known as fetal microchimerism.
There are five basic stem cells classifications there is embryonic stem cells, fetal stem cells. There are the Umbilical cord stem cells, placenta stem cells, and lastly there are adult stem cells.
Multipotent stem cells

The umbilical cord has stem cells in it. Baby teeth are another possible source of stem cells.
The use of stem cells is not unethical in and of itself, the ethics component revolves around the source of the stem cells and the concern that fetuses will be produced and intentionally destroyed in order to obtain stem cells.

yes it is
