Question

Dr. O has a culture of identical stem cells growing in various petri dishes. He succeeds in causing the cells in one dish to specialize into red blood cells. The stem cells in another dish are stimulated to specialize into white blood cells. He unsuccessfully attempts to convert the stem cells in the third dish into skin cells – no luck. What type of cells did he most likely have growing in his three dishes?

A. pluripotent stem cells

B. haploid egg cells

C. specialized blood cells

D. bacteria cells

E. multipotent stem cells

Explanation / Answer

Answer:

A. pluripotent stem cells

Explanation:

A pluripotent stem cell is one that has the potential to differentiate into any type of human tissue but cannot support the full development of an organism. These cells then become slightly more specialized, and are referred to as multipotent cells. A multipotent stem cell has the potential to differentiate into different types of cells within a given cell lineage or small number of lineages, such as a red blood cell or white blood cell.
