肿瘤内的血管形成方式有三种 ,即肿瘤血管生成、血管生成拟态 (vasculogenicmimicry)和马赛克血管(mosaicvessel)。肿瘤血液供应来源于宿主 ,但肿瘤内的血管却因为适应肿瘤异常的生物学行为 ,在结构和功能上与正常血管有一定的差异。肿瘤血管的特殊结构有利于肿瘤组织生长、侵袭和转移 There are three ways of forming blood vessels in tumors, namely tumor angiogenesis, vasculogenic mimicry and mosaicvessel. The blood supply of the tumor comes from the host, but the blood vessels in the tumor have certain structural and functional differences from the normal blood vessels because they adapt to the abnormal biological behavior of the tumor. The special structure of tumor blood vessels is conducive to tumor growth, invasion and metastasis
