From which type of cells are B lymphocytes and T lymphocytes derived?

B lymphocytes and T lymphocytes are derived from hematopoietic stem cells. These stem cells, located primarily in the bone marrow, are responsible for the production of all types of blood cells, including lymphocytes. Hematopoietic stem cells differentiate into various progenitor cells, which then mature into specialized immune cells like B and T lymphocytes.

B cells, which are essential for humoral immunity, mature in the bone marrow and are responsible for producing antibodies. T cells, critical for cell-mediated immunity, mature in the thymus after being derived from the same hematopoietic stem cells. The critical role of hematopoietic stem cells in generating the cells involved in the adaptive immune response emphasizes their importance in immunology and hematopoiesis.

The other options refer to different types of stem cells. Pluripotent stem cells have the potential to differentiate into nearly all cell types in the body, but they do not specifically lead to the formation of B and T lymphocytes. Mesenchymal stem cells primarily give rise to connective tissue cells, such as osteoblasts and adipocytes, not lymphocytes. Myeloid stem cells are precursors to various types of blood cells, including red blood cells and granulocytes,
