Organs that are rich in collagen such as liver, lungs, and bone are frequently sites of tumor cell metastasis. In this study, we have found that cultured tumor cells of human and rat origin migrated unidirectionally in response to collagen in vitro. Synthetic di- and tri-peptides that contained amino acid sequences found frequently in the collagen helix caused similar effects. These results are consistent with the hypothesis that collagen or collagen fragments released during connective tissue remodeling may be important in tumor cell metastasis.
富含胶原蛋白的器官,如肝脏、肺和骨骼,常常是肿瘤细胞转移的部位。在本研究中,我们发现源自人和大鼠的培养肿瘤细胞在体外对胶原蛋白产生单向迁移反应。含有胶原蛋白螺旋中常见氨基酸序列的合成二肽和三肽也产生了类似的效果。这些结果与以下假设一致:在结缔组织重塑过程中释放的胶原蛋白或胶原蛋白片段可能在肿瘤细胞转移中起重要作用。
