Which stem cell type is capable of differentiating into many, but not all, cell types?

1. The totipotent stem cell is the zygote and gives rise to every cell of the body, so it is not limited. 2. One level down sits the pluripotent stem cell, which gives rise to multiple types of body cells and some supporting fetal membranes, but not to all of them. 3. That is exactly the description of many but not all cell types. 4. The mesenchymal and myeloid cells sit lower still and are narrower again, so neither is the level being described. _Source: OpenStax Anatomy and Physiology (CC BY 4.0), Ch 18 "The Cardiovascular System: Blood", section 18.2 Production of the Formed Elements_
