Define lymphocytopoiesis.

Lymphocytopoiesis is the formation and maturation of lymphocytes from hematopoietic stem cells. It encompasses the development of B lymphocytes in the bone marrow and T lymphocytes in the thymus (with NK cells arising from the same lymphoid progenitors), preparing these cells to populate secondary lymphoid tissues. This process is separate from lymphatic vessel development (lymphangiogenesis) and from the functions of mature lymphocytes—such as antibody secretion by plasma cells or the phagocytic activity of macrophages—since those are actions of differentiated cells, not the production of lymphocytes themselves.
