What type of cells can give rise to all types of specialized cells, including placental cells?

Understand the Problem

The question is asking which type of stem cells has the capability to differentiate into all types of specialized cells, including those that form the placenta. It specifically lists options that describe different potentialities of stem cells.

More Information

Totipotent stem cells have the unique ability to form all cell types, including both embryonic and extraembryonic (such as placental) cells, in an organism. They are present shortly after fertilization.

Tips

A common mistake is confusing pluripotent stem cells with totipotent stem cells. Pluripotent cells can form all cell types in the body, but cannot form placental cells.
