Measurement of Aortic Cell Fluid-Phase Pinocytosis in vivo by Flow Cytometry.

Abstract excerpt

OBJECTIVE: Fluid-phase pinocytosis is a receptor-independent mechanism of endocytosis that occurs in all mammalian cells and may be a mechanism for the uptake of LDL by macrophages. As there are currently no methods for the measurement of fluid-phase pinocytosis by individual aortic cells in vivo, we sought to identify a suitable method. METHODS: ApoE-/- mice were retro-orbitally injected with AngioSPARK...
