肿瘤血管生成在肿瘤的发展过程中起着关键作用。外周循环血中存在的一些髓样细胞,如巨噬细胞、中性粒细胞、酸性粒细胞、肥大细胞和树突状细胞等具有多方面的能力,被募集到肿瘤组织中,在肿瘤微环境中促进肿瘤的血管生成。这些髓样细胞在肿瘤血管生成过程中起重要的作用。该文对这些不同类型细胞促进肿瘤血管生成的作用进行了论述。 Tumor angiogenesis plays a key role in the development of tumors. Peripheral blood circulation in some of myeloid cells, such as macrophages, neutrophils, acid granulocytes, mast cells and dendritic cells have a multi-faceted ability to be recruited to the tumor tissue in the tumor microenvironment In promoting tumor angiogenesis. These myeloid cells play an important role in tumor angiogenesis. This article discusses the role of these different types of cells in promoting tumor angiogenesis.
