Diapedesis is a well-understood process, and researchers believed that other types of cells, like therapeutic stem cells or even metastatic cancer cells, exited blood vessels in a similar way, with the cells pushing or squeezing themselves out.

ICAM2 mediates transmigration independently and PECAM1 participates in diapedesis in a cytokine specific manner (35).
Chemoattractant factors, which include monocyte chemoattractant protein-1 produced by vascular wall cells in response to modified lipoproteins, direct the migration and diapedesis of adherent monocytes (24, 25).
Esterases are enzymes also related to cellular defense, facilitating diapedesis, cell migration through tissue, toxic product and microorganism inactivation and tumour cell destruction (Hayhoe & Quaglino; Casaletti-Rosa & Lunardi, 1997; Azevedo & Lunardi).
Thromboxane mediates diapedesis after ischemia by activation of neutrophil adhesion receptors interacting with basally expressed intercellular adhesion molecule-1.

Numerous individual hemocytes containing India ink were eliminated from the clams by diapedesis over lumenal epithelial surfaces (Fig.
The presence of this enzyme in pallial fluid of both clams and oysters is likely a result of diapedesis of hemocytes into the mantle cavity and/or mantle epithelial cell secretions.
Such dilation may also cause diapedesis of cells and proteins into the subarachnoid space, explaining the reticulocytes, xanthochromia, mononuclear pleocytosis and increased protein found in CSF from patients with SIH or ICH.
El exudado hemorragico se observa en infecciones sistemicas, como las causadas por salmonelosis, posiblemente debido a la liberacion de toxinas por parte de la bacteria, que generan vasculitis pulmonar aguda (capilaritis), produciendose el aumento de la permeabilidad capilar y la consiguiente salida de eritrocitos al espacio extracelular por diapedesis (Gazquez, 1991; Novoa et al.
