Question

Identify the wrong statement with respect to embryonic stem cells.

• A. They are pluripotent.
• B. They are isolated from epiblast tissue of blastocyst.
• C. They cannot proliferate in culture medium.
• D. They can give rise to the three germination layers.

Answer 1

Answer: (C)

They cannot proliferate in culture medium.

Embryonic stem cells are derived from embryos. In human beings, they are derived from inner cell mass of 3 to 5 days old hollow microscopic ball of cells called blastocyst.

Blastocyst is isolated and transferred into a culture dish that contain a nutrient broth. In few days, cells of inner cell mass proliferate and begin spread over the surface of dish.

These proliferated stem cells are pleuripotent and referred to as embryonic stem line.

So, the correct answer is 'They cannot proliferate in culture medium'
