The physiological characteristics of the basal microvilli microvessels in pancreatic cancers

Pancreatic cancer(PC)is a highly lethal tumor with controversial high glucose uptake and hypomicrovascularity.And,the hypomicrovasculature,which is considered to have poor perfusion,blocks the delivery of drugs to tumors.Previously,we described the preferential existence of a novel endothelial projection with trafficking vesicles in PCs,referring to basal microvilli.However,whether the basal microvilli microvessels have good perfusion or deliver nutrients to the tumor milieu is unknown.Here,we perfused multiple endothelial markers and nutrients to autochthonous PC-bearing mice to study the nutrient trafficking and perfusion status of the basal microvilli microvasculature.
