1肿瘤浸润转移的过程和机理肿瘤的浸润和转移过程极为复杂,大致为:①血管生成。②肿瘤细胞从原发灶脱落。③与细胞外基质(包括基底膜)发生粘附并使之降解。④穿越血管壁进入循环并到达远处部位。这是个多步骤、多阶段的级联式反应过程,涉及肿瘤细胞与宿主细胞的一系列相互作用,
A tumor invasion and metastasis of the process and mechanism of tumor invasion and metastasis process is extremely complex, roughly: angiogenesis. ② tumor cells shed from the primary tumor. ③ and the extracellular matrix (including the basement membrane) adhesion and degradation. ④ through the blood vessel wall into the circulation and reach the distant parts. This is a multi-step, multi-stage cascade of reaction processes involving a series of interactions of tumor cells with host cells,
