Contrast-enhanced ultrasound for the evaluation of CXCR7-mediated angiogenesis in colon cancer

ABSTRACT: Background: The purpose of this study was to clarify the effect of C-X-C chemokine receptor type 7 (CXCR7) on proliferation, migration, and angiogenesis by changing the expression levels of CXCR7 in colon cancer cells. Contrast-enhanced ultrasound technology was used to quantify tumor perfusion parameters in vivo for the detection of angiogenesis after the change of CXCR7 expression in colon cancer xenografts. Methods: To detect the expression of CXCR7 in colon cancer cells after overexpression or silencing of CXCR7. In addition, proliferation, migration, and angiogenesis were determined. The region of interest of the tumor was selected, and a time-intensity curve was drawn. Immunohistochemical staining was performed on tumor tissue sections, and the average microvessel density value was c
