Immune regulation by the peripheral lymphatics
... While the role of the lymphatics system in regulating cell migration is well established, there is strong circumstantial evidence to suggest an additional role in regulating cellular activation. However, these mechanisms have largely not been confirmed in vivo and as such the relative importance of ...

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.
