Animal Stem Cells and Regeneration · Zoology

Which type of stem cell has the potential to differentiate into all cell types of the body, including extraembryonic tissues like the placenta?

  1. Pluripotent stem cells
  2. Multipotent stem cells
  3. Totipotent stem cells
  4. Unipotent tissue-specific stem cells
Show answer and explanation

Correct answer: Totipotent stem cells

Totipotent stem cells, such as the zygote and early blastomeres, have the highest level of potency. They can generate an entire organism along with the necessary supporting extraembryonic membranes.
