Question

Stem cells are self-renewing, undifferentiated cells that divide by mitosis to produce specific body cell types. There are two broad types of stem cells, namely, adult and embryonic. Which of the following is correct?

Answer 1

• Stem cells are a class of undifferentiated cells that are able to differentiate into specialized cell types by mitosis. Commonly, stem cells come from two main sources:
  

1. Embryos formed during the blastocyst phase of embryological development (embryonic stem cells)

2. Adult tissue (adult stem cells) that regenerate the damaged tissues.

• Both types are generally characterized by their potency, or potential to differentiate into different cell types (such as skin, muscle, bone, etc.)
  
• Both of the given statements are correct.
