Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

What type of cells can divide and renew themselves for long periods of time, remain undifferentiated in form, and differentiate into a variety of specialized cells?

A	cancer cells
B	brain cells
C	stem cells
D	animal cells

Explanation:

Detailed explanation-1: -Stem cells are unspecialized cells of the human body. They are able to differentiate into any cell of an organism and have the ability of self-renewal. Stem cells exist both in embryos and adult cells. There are several steps of specialization.

Detailed explanation-2: -Stem cells are undifferentiated or “blank” cells that have not yet fully specialized. Under proper conditions, stem cells begin to develop into specialized tissues and organs. Additionally, stem cells can self-renew, that is they can divide and give rise to more stem cells.

Detailed explanation-3: -Adult Stem Cells (ASCs): ASCs are undifferentiated cells found living within specific differentiated tissues in our bodies that can renew themselves or generate new cells that can replenish dead or damaged tissue. You may also see the term “somatic stem cell” used to refer to adult stem cells.

Detailed explanation-4: -Stem cells are unspecialized cells that can self-renew indefinitely and that can also differentiate into more mature cells with specialized functions.
