Which of the following contains the greatest number of unipotent stem cells? a. 6-week-old embryo b. blastocyst c. adult d. 3-day-old embryo

The correct answer is option C

Unipotent stem cells are those stem cells that can form cells of one lineage only. An adult would be having the maximum number of unipotent stem cell as it has gone through the process of cell differentiation and the cell have been differentiated into different kinds of cells. For example: skin stem cells

The stem cells of embryo are mainly pleuripotent and multipotent that can form cells of different lineages.
