Figure 1From: Urea immunoliposome inhibits human vascular endothelial cell proliferation for hemangioma treatmentUrea immunoliposome morphology. (A) Both the urea liposome and urea immunoliposome generated a suspension that appeared milky white upon gross inspection. (B) Urea immunoliposomes diluted 100 times observed under a transmission electron microscope (×150,000).Back to article page
