The Neutrophilic Cellular Penetration

Vaginal smears have been taken from Awassi sheep in 2006. The smears were stained by methylene blue. The relation between the exfoliated vaginal cells and the neutrophils were examined under light microscope. Firstly, this study revealed that the neutorphils were unable to phagocytize the larger size cells directly, however they can attack and kill them according to the theory of neutrophilic cellular penetration registered firstly in this study. This theory containes five steps. The direct process of true phagocytosis of these large cells have been done by another larger phagocytic cell.
