The entire process of blood vessel escape is known as diapedesis. Once in the interstitial fluid, leukocytes migrate along a chemotactic gradient towards the site of injury or infection.
Diapedesis is defined as the process by which white blood cells migrate from blood vessels into tissues in response to tissue damage, infection, or inflammation.
Once firmly adhered, the leukocyte performs diapedesis, or transmigration, which is the physical passage across the vascular wall. The cell flattens and reorganizes its internal skeleton, using its adhesive molecules to crawl toward the junction between two endothelial cells.
This review will focus on recent advances in our understanding of mechanism of leukocyte crawling and diapedesis, with an emphasis on leukocyte–endothelial interactions and the signaling pathways they transduce to determine the mode of diapedesis, junctional or non-junctional.
diapedesis the passage of white blood cells through the unruptured wall of a blood vessel by changing in shape; an important reaction to tissue injury, leading to inflammation.
Diapedesis is the process by which white blood cells, known as leukocytes, move from the bloodstream into surrounding tissues. It allows cellular defenders to exit the circulatory system and travel directly to sites of injury or infection.
The meaning of DIAPEDESIS is the passage of blood cells through capillary walls into the tissues.
Diapedesis is the process by which white blood cells (leukocytes) move through the walls of capillaries and enter the tissues to reach sites of infection or injury.
