Lymphoid stem cells in the bone marrow give rise to two primary types of immune cells: natural killer (NK) cells and B lymphocytes. NK cells are part of the innate immune system, providing rapid responses to infected or cancerous cells. B lymphocytes, part of the adaptive immune system, produce antibodies. Platelets and neutrophils, on the other hand, originate from myeloid stem cells, not lymphoid stem cells.
