Emperipolesis: Sternal and Femoral Microenvironment Induces Megakaryiocyte Emperipolesis in the Wistar Strain [PDF]
Macedonian Veterinary Review, 2019 Abstract Emperipolesis is considered a physiological phenomena often present in various pathophysiological conditions, but its etiology is still unknown. In this study, we analyzed the number of megakaryocytes and the percentage of emperipoletic cells in the sternal and femoral bone marrow of Wistar rats.

JOURNAL OF CLINICAL AND DIAGNOSTIC RESEARCH, 2014 Emperipolesis is an uncommon biological process, in which a cell penetrates another living cell. Unlike in phagocytosis where the engulfed cell is killed by lysosomal enzymes of the macrophage, the cell exists as viable cell within another in emperipolesis and can exit at any time without any structural or functional abnormalities for either of them ...

Revista de la Asociación Colombiana de Dermatología y Cirugía Dermatológica, 2002 La emperipolesis es la capacidad que tienen los linfocitos, plasmocitos y polimorfonucleares de penetrar al citoplasma de otras células, usualmente gigantes, sin sufrir daño en el proceso. Su significado es desconocido. Es un rasgo morfológico muy útil en el diagnóstico histopatológico de algunas enfermedades como la de Rosai-Dorfman, la micosis ...
