Chapter 9: Stem Cell Culture and Organ Culture — Important Questions & Answers
A stem cell is best defined as a cell that can:
- A. Self-renew and differentiate into specialised cell types
- B. Only divide once and then die
- C. Perform photosynthesis in culture
- D. Produce antibodies without differentiation
Answer: A. Self-renew and differentiate into specialised cell types
Stem cells have the ability to self-renew and give rise to specialised cells under suitable conditions.

Embryonic stem cells are commonly obtained from which part of the early embryo?
- A. Trophoblast
- B. Inner cell mass of blastocyst
- C. Placenta
- D. Amniotic fluid only
Answer: B. Inner cell mass of blastocyst
Embryonic stem cells are derived from the inner cell mass of the blastocyst stage embryo.
Embryonic stem cells are derived from the inner cell mass of the blastocyst stage embryo.
Compared with most adult stem cells, embryonic stem cells generally have:
- A. Greater differentiation potential
- B. No ability to divide
- C. Only one possible cell fate
- D. No requirement of culture medium
Answer: A. Greater differentiation potential
Embryonic stem cells are pluripotent, whereas most adult stem cells are multipotent and more restricted in their differentiation capacity.
Embryonic stem cells are pluripotent, whereas most adult stem cells are multipotent and more restricted in their differentiation capacity.
A researcher wants cells that can generate many different body cell types for studying early development, but must also consider ethical issues. Which cells are being referred to?
- A. Embryonic stem cells
- B. Mature red blood cells
- C. Fully keratinised dead skin cells
- D. Bacterial cells
Answer: A. Embryonic stem cells
Embryonic stem cells are pluripotent and useful for developmental studies, but their use raises ethical concerns.
Embryonic stem cells are pluripotent and useful for developmental studies, but their use raises ethical concerns.
In stem cell biology, asymmetric division is important because it can produce:
- A. One stem cell and one committed progenitor cell
- B. Two dead cells only
- C. Only extra-embryonic membranes
- D. Four gametes directly by mitosis
Answer: A. One stem cell and one committed progenitor cell
Asymmetric division helps maintain the stem cell pool while also producing cells that can enter a differentiation pathway.
