Development of lymphocyte populations in lymph nodes of the mouse

Abstract

Lymphocytic colonization of lymph nodes in mouse is studied. Lymphocytes are first seen through the walls of post-capillary venules in diapedesis and nodal parenchyma on the second day after birth. Large lymphocytes are observed in nodal parenchyma between the 4th and 6th day. The nodular pattern appears on the 24th day with development of primary nodules.
