恶性肿瘤的转移是引起宿主死亡的重要原因之一。转移是一个多步骤的肿瘤与宿主相互作用的复杂过程,恶性肿瘤的转移主要是肿瘤细胞或其细胞栓侵入血管(或淋巴管)—随血流(或淋巴流)运行—在靶器官的微细血管着落—逸出血管进入正常组织—肿瘤细胞增殖并诱发血管生成,最终形成转移瘤。以上步骤中任何一步得以控制,其转移都不能实现。继发现Neuratropin(NSP)具有抗转移作用之后,为寻找更有效的抗转移方法。本文设 Malignant tumor metastasis is one of the important causes of host death. Metastasis is a multi-step complex process in which a tumor interacts with a host. The metastasis of a malignancy is primarily the infiltration of tumor cells or their suppositories into blood vessels (or lymphatics)—operating with blood flow (or lymph flow)—in the fineness of the target organ. Vascular landing - escape from blood vessels into normal tissue - tumor cells proliferate and induce angiogenesis, eventually forming metastases. Any one of the above steps is controlled and its transfer cannot be achieved. Following the finding that Neuratropin (NSP) has an anti-metastatic effect, a more effective anti-metastasis method was sought. This article
