Question

Banking stem cells is a very popular practice in science. This is when stem cells, located in the umbilical cord of a birthed infant, are saved and frozen. Why could this be a beneficial practice?
A)Stem cells are already differentiated but can still replace different cells located in the body
B)Stem cells should not be saved because all cells of the body can be used as stem cells
C)Stem cells are undifferentiated and therefore, could be used to grow into any kind of cell of the body
D)In case of an emergency, it is always good to have a lot of cells on hand since they cannot replace themselves

Answer 1

The answer is C. stem cells are undifferentiated.

Answer 2

Banking stem cells are located in the umbilical cord of a birthed infant, are saved and frozen.This storage is beneficial because Stem cells are undifferentiated and therefore, could be used to grow into any kind of cell of the body.

Answer: Option C

Explanation:

When the zygote is formed it contains only one cell which divides continuously to form a complete organism, on this note the cells that are formed initially are not confined to a single type rather they are undifferentiated and therefore on proper signalling can be differentiated into any number of cells.
