CHAPTER 17 ONTOGENY OF THE IMMUNE SYSTEM
... In normal human adults, the generation of all cells of the hematopoietic system, with one important exception, is restricted to the bone marrow. We’ve already discussed this exception in Chapter 13; while B-cells (and most other blood cells) are produced within the bone marrow, mature T-cells are pr ...

Lymphopoiesis
Lymphopoiesis (lĭm'fō-poi-ē'sĭs) (or lymphocytopoiesis) is the generation of lymphocytes, one of the five types of white blood cell (WBC). It is more formally known as lymphoid hematopoiesis.Pathosis in lymphopoiesis leads to any of various lymphoproliferative disorders, such as the lymphomas and lymphoid leukemias.
