Explanation:
Detailed explanation-1: -Where can scientists obtain stem cells? Note: Stem cells can also be obtained from a fetus, umbilical cord blood or by using a recently developed technique to ‘reprogramme’ specialized body cells so that they behave like embryonic stem cells.
Detailed explanation-2: -There are four main sources of stem cells, i.e. embryonic tissues, fetal tissues, adult tissues and differentiated somatic cells after they have been genetically reprogrammed, which are referred to as induced pluripotent stem cells (iPSCs).
Detailed explanation-3: -c) Stem cells are determined cells that reside in fully differentiated tissues and can, when needed, differentiate to supply new cells for growth of the tissue.
