[Establishment and biologic properties of a mouse uterine cervix cancer cell line (MUCC) with lymphatic and hematogenous metastatic capacities].
For study of tumor metastatic mechanism, a mouse uterine cervix cancer cell line (MUCC), as derived from a transplantable mouse uterine cervix cancer No. 27 (U 27) with metastatic capacities through lymphatics and blood, was established in vitro. It has been successfully maintained for more than 24 months through more than 100 passages. MUCC cells are epithelioid with definite malignant morphological features. The doubling time of the cell population is 27.8 hours. The average mitotic index is 30.6%, with a maximum of 58.9%. Chromosomes show aberration in number and structure. The homotransplant rate is 75% (9/12). The solid tumor, produced by homotransplant, is similar to the tumor U 27. Metastases are present in the lymph nodes and lungs in these 9 animal models. It is evident that this cell line retains the capacity of inducing daughter tumor lines with spontaneous lymphatic and blood metastases. MUCC cell line might be very useful in isolating subpopulations which possess the different metastatic abilities and the study of metastatic mechanism.
