Which type of stem cell produces cells that subsequently enter meiosis?

• A. Germline stem cells
• B. Neural stem cells
• C. Hematopoietic stem cells
• D. Mesenchymal stem cells

Answer: (A)

Verified step by step guidance

1. Understand the role of stem cells: Stem cells are undifferentiated cells capable of dividing and differentiating into specialized cell types. Different types of stem cells have specific roles in the body.
2. Identify the process of meiosis: Meiosis is a type of cell division that reduces the chromosome number by half, producing gametes (sperm or eggs) in sexually reproducing organisms. Only certain stem cells are involved in producing cells that undergo meiosis.
3. Analyze the options: Germline stem cells are responsible for producing gametes and are the only type of stem cell that gives rise to cells entering meiosis. Neural stem cells, hematopoietic stem cells, and mesenchymal stem cells are involved in producing other specialized cells (e.g., neurons, blood cells, and connective tissue cells, respectively) and do not participate in meiosis.
4. Focus on germline stem cells: Germline stem cells are located in the gonads (testes in males and ovaries in females) and divide to produce precursor cells that will enter meiosis to form gametes.
5. Conclude the reasoning: Based on the biological function of germline stem cells, they are the correct answer as they produce cells that subsequently enter meiosis, unlike the other types of stem cells listed.
