Fig. 4From: Long non-coding RNA UBE2CP3 enhances HCC cell secretion of VEGFA and promotes angiogenesis by activating ERK1/2/HIF-1α/VEGFA signalling in hepatocellular carcinomaUBE2CP3 promoted angiogenesis in vivo. a CAM angiogenesis assays showed that when injected with HCC cells overexpressing UBE2CP3, the density of new chick embryo vessels increased. b Chick embryos injected with UBE2CP3 knockdown cells had decreased new vessel density. c CD31/PAS double-staining results showed that mice injected with cells overexpressing UBE2CP3 had higher EV density in the tumor tissue than those injected with Lv-control cells. d Mice injected with UBE2CP3 knockdown cells had lower EV density in the tumor tissue than those injected with the sh-control cellsBack to article page
