Question

You have a culture of stem cells growing in a flask in a laboratory. You separate the cells into various dishes and cause them to specialize into different types of cells. You find that you can cause the stem cells to specialize into either red blood cells or white blood cells, but you cannot coax themto specialize into muscle cells or nerve cells. Which of the following is a valid conclusion about your line of stem cells, based on this information?

a.	The cells are pluripotent stem cells.

b.	The cells were originally derived from a blastocyst.

c.	The cells are multipotent stem cells.

d.	The cells were taken from a cancer patient.

e.	The cells were originally derived from white blood cells.

Answer 1

Answer is C. The cell are multipotent stem cells.

because multipotent cells have been found in cord blood, adipose tissue, cardiac cells, bone marrow, and mesenchymal stem cells (MSCs) which are found in the third molar. In the given information, stem cell cause to specialize either red blood cell or white blood cell but not muscle cell or nerve cell. RBC and WBC have capacity to self renew by dividing and to develop into multiple specialized cell types.
