XII.E.002

Mononuclear Leukocyte Egress. Murine marrow. Monocyte showing an initial small pseudopod penetrating endothelium and entering sinus lumen (L). Note endothelial cell junction (arrow) to the right of migration pore. (Transmission electron micrograph)

XII.E.003

Mononuclear Leukocyte Egress. Murine marrow. Monocyte showing an initial small pseudopod penetrating endothelium and entering sinus lumen (L). Above the forward part of a lymphocyte has entered the sinus lumen. Note the profound deformation of the nucleus required to pass through the small pore in the endothelial cell. Segmented nuclei of granulocytes in egress do not require this degree of deformation. (See Part XII. D.) (Transmission electron micrograph)
