What type of cells have a limited capacity for division compared to stem cells?

• A. Progenitor cells
• B. Differentiated cells
• C. Stem cells
• D. All of the above

Answer: (A)

Progenitor cells have a limited capacity for division compared to stem cells because they are more specialized. While stem cells have the ability to divide indefinitely and can differentiate into multiple cell types, progenitor cells arise from stem cells and have already begun the process of specialization. They can proliferate but only a finite number of times before they differentiate into specific cell types. Differentiated cells, on the other hand, have typically reached a final, specialized state and generally do not divide. Thus, while they represent the end-stage of cell development, they are not the focus of this question. Stem cells possess the unique quality of self-renewal and can continue to divide and replenish themselves indefinitely. Progenitor cells, however, do not have this unbounded capacity and are thus categorized distinctly because of their transitional role between stem cells and fully differentiated cells.
