Question

Are human cells totipotent?

Answer 1

Totipotent cells:

1. A totipotent cell can differentiate and give rise to extraembryonic tissue,
2. In humans, the zygote (fertilized egg) and blastomeres (two-cell stage) are totipotent.
3. They can give rise to all the three germ layers- endoderm, ectoderm, and mesoderm.
