肿瘤细胞的侵袭是肿瘤扩散和转移的基础。为何具有侵袭能力以及怎样侵袭,是研究制服恶性肿瘤的重要课题之一。本文用肺腺癌细胞(LTEP—a—2)和肺巨细胞癌克隆D株(PLA—801)为攻击细胞,胎儿膈肌或胎鼠心脏为靶器官,将攻击细胞种植在靶器官表面,以1640培养液进行培养。结果表明,在培养24小时,肺癌细胞与靶器官紧密靠近,匍匐其上,并见癌细胞伸出伪足或以微绒毛与靶器
The invasion of tumor cells is the basis of tumor proliferation and metastasis. Why invasion ability and how to attack is one of the important topics in the study of malignant tumors in uniforms. In this study, lung adenocarcinoma cells (LTEP-a-2) and lung giant cell carcinoma clone D strain (PLA-801) were used as challenge cells. The target organs of fetal diaphragm or fetal heart were used as target cells. The challenge cells were planted on the surface of target organs. Culture medium for 1640 culture. The results showed that in cultured cells for 24 hours, the lung cancer cells were in close proximity to the target organs, and the cancer cells protruded, and that the cancer cells protruded from the pseudopod or microvilli and the target.
