In the context of brain-tissue implants, what is unique about stem cells?

A) They survive for extended periods outside of the body.
B) They can develop into most types of human cells.
C) They are insusceptible to the effects of plasticity.
D) They transfer genetic information into human cells.

Stem cells are unique because they have the ability to differentiate into many different types of cells, including brain cells. This makes them a promising candidate for brain tissue implants, as they can potentially replace damaged or lost brain cells. Stem cells also have the ability to self-renew, meaning they can divide and create new stem cells, which increases their potential for long-term survival and effectiveness in the body.
