title: [In vitro quantitative study on invasive process of two human nasopharyngeal carcinoma cell lines, CNE-1 and CNE-2Z].
abstract: Computer-image processing system was used in the quantitative study on invasion in organ culture of two human nasopharyngeal carcinoma cell lines of different degree of differentiation, CNE-1 and CNE-2Z. For invasion of tumor cells into precultured heart fragments (PHF), observations were done on days 1,3,5 and 7 after organ culture. The results showed that the invasion of both CNE-1 and CNE-2Z cells was progressive. The invasion of CNE-1 tumor cells covered 82.22% of PHF on day 7, but on days 1 to 3 the invasion of CNE-2Z tumor cells covered 80-92% of PHF. This indicates that CNE-2Z cells are more invasive then CNE-1 cells.
