Pluripotent: These cells are a little more restricted, coming from the Extra-embryonic layers. These can become things assigned to the layers. (Endo, ecto, meso)
Multipotent: These cells can only become specific things. Example is when a cell becomes endodermic, it can only be any gastrointestinal cells, or any other inner organ, excluding the heart and nervous system. ]]> 2018-11-08 20:22:02 UTC https://padlet.com/boehmersm/yd35ahp84ypf/wish/302313505 boehmersm https://padlet.com/boehmersm/yd35ahp84ypf/wish/302317794 The amniotic sac and fluid is essentially what protects the baby.
