Select an option to attempt
Correct Answer: Option A
Explanation
Pluripotent stem cells — differentiation potential:Pluripotent stem cells can differentiate into virtually any cell type in the body (all ~200 somatic cell types from all three germ layers):• Ectoderm: skin, neurons, sense organs• Mesoderm: muscle, bone, blood, connective tissue• Endoderm: gut epithelium, liver, lung, pancreasHowever, pluripotent cells CANNOT form trophoblast cells (which form the placenta and extraembryonic membranes). Only totipotent cells can.Examples of pluripotent cells:• Embryonic Stem Cells (ESCs): from inner cell mass of blastocyst• Induced Pluripotent Stem Cells (iPSCs): adult cells reprogrammed by Yamanaka factors (Oct4, Sox2, Klf4, c-Myc)Answer: Pluripotent stem cells differentiate into any of ~200 cell types from three germ layers but cannot form trophoblast (placenta).
