肿瘤内新生血管生成在恶性实体瘤的发生、发展和转移中起重要作用,它既是一个多种因子调控的复杂过程,又影响肿瘤的血供。既往的血管生成研究显示胰腺癌组织中微血管密度升高,但介入放射学检查显示胰腺癌却表现为乏血管肿瘤。为进一步研究胰腺癌的血管生成特征,我们应用免疫组
Tumor neovascularization plays an important role in the occurrence, development and metastasis of malignant solid tumors. It is not only a complicated process regulated by many factors, but also affects the blood supply of tumors. Previous studies of angiogenesis showed increased microvessel density in pancreatic cancer but interventional radiology revealed pancreatic cancer as a lack of vascular tumors. To further investigate the angiogenic characteristics of pancreatic cancer, we applied the immunization group
