Megakaryocyte emperipolesis arms neutrophils via intracellular provisioning
Neutrophils are phenotypically heterogenous cells that mediate host defense and tissue homeostasis. Here, we identify emperipolesis - the evolutionarily conserved process by which neutrophils pass through megakaryocytes - as a phenotypically transformative route of egress from bone marrow. By intravital microscopy and 3-D histology, we show that the rapid form emperipolesis is markedly enhanced…
