Abstract: In this paper, the infiltration ability of human esophageal cancer cell line (ECa-109), human hepatocellular carcinoma cell line (BEL-7402) and normal Chinese hamster ovary cell line (CHO) to the kidney and myocardium of chicken embryo was studied by the method of co culture of double agar in vitro organs and experimental cells. The results showed that both ECa-109 cells and BEL-7402 cells had infiltration ability in vitro, and the infiltration ability of ECa-109 was stronger than that of BEL-7402 cells. Normal CHO cells had no infiltration ability and could only slightly attach to the target tissue. The kidney and myocardium of chicken embryo had the same ability to accept malignant cell ECa-109 and BEL-7402 infiltration.
