What is the role of stem cells in the body?
A
fight against infection
B
provide specialised roles in the body
C
used for fertility treatment
D
they produce new specialised cells in the body to replace old cells that are used up
Explanation: 

Detailed explanation-1: -Under the right conditions in the body or a laboratory, stem cells divide to form more cells called daughter cells. These daughter cells become either new stem cells or specialized cells (differentiation) with a more specific function, such as blood cells, brain cells, heart muscle cells or bone cells.

Detailed explanation-2: -The stem cells can be used to grow a specific type of tissue or organ. This can be helpful in kidney and liver transplants. The doctors have already used the stem cells from beneath the epidermis to develop skin tissue that can repair severe burns or other injuries by tissue grafting.

Detailed explanation-3: -What is the role of stem cells with regard to the function of adult tissues and organs? a) Stem cells are undifferentiated cells that divide asymmetrically, giving rise to one daughter that remains a stem cell and one daughter that will differentiate to replace damaged and worn out cells in the adult tissue or organ.

Detailed explanation-4: -Stem cells are undifferentiated cells found in most of multicellular animals. These cells maintain their undifferentiated state even after undergoing numerous mitotic divisions. Stem cell research has the potential to revolutionize the future of medicine with the ability to regenerate damaged and diseased organs.
