A
they are undifferentiated cells which are able to develop into one or more types of specialised cells. adult stem cells can be found in specific parts of the human body, for example bone marrow; they can only form certain cells, bone marrow can only differentiate into types of blood. embryotic stem cells can be found in early human embryos and can differentiate into any type of specialised cells.
