Question 83 – Foundations in biology - Questions

In a developmental biology study, three distinct populations of mammalian stem cells (designated $P$ , $Q$ , and $R$ ) are isolated and their differentiation potentials are analysed:

Population $P$ : Isolated from a 4-cell embryo. These cells can differentiate into any embryonic cell type as well as extra-embryonic tissues such as the placenta.
Population $Q$ : Isolated from the inner cell mass of a blastocyst. These cells can differentiate into cells of all three embryonic germ layers (ectoderm, mesoderm, and endoderm), but cannot form extra-embryonic tissues.
Population $R$ : Isolated from the hematopoietic niche of adult bone marrow. These cells can differentiate into erythrocytes, neutrophils, and platelets.

Which of the following options correctly classifies the potency of these three stem cell populations?

Population $P$ is pluripotent; Population $Q$ is totipotent; Population $R$ is multipotent

Population $P$ is totipotent; Population $Q$ is pluripotent; Population $R$ is multipotent

Population $P$ is totipotent; Population $Q$ is multipotent; Population $R$ is unipotent

Population $P$ is pluripotent; Population $Q$ is multipotent; Population $R$ is unipotent
