ABSTRACT

The growth and metastasis of four human intestinal tumor cell lines: one duodenal adenocarcinoma (HTB-40) and three adenocarcinomas of the colon (CCL-218, CCL-222 and HT-29) have been compared in vitro and in vivo in nude mice. HTB-40 was the fastest growing cell line in vitro with a doubling time (DT) of 14.8 h. CCL-218 and CCL-222 grew more slowly in vitro with doubling times of 21.6 and 22.8 hours, respectively. All three of these tumors grew more slowly in vivo with doubling times ranging from 39.1 h (CCL-218 in male nude mice) to 65.3 h (CCL-222). The growth of CCL-218 cells was significantly slower in female nude mice DT 51.0 h). HT-29 was the slowest growing in vitro (DT 23.8 h) and in vivo (DT about 100 h). HT-29 also showed the greatest discrepancy between its DT measured in vivo as compared to in vitro, suggesting a greater clonogenic cell loss from HT-29 tumors in vivo. Histologic evaluation of these tumors grown subcutaneously in nude mice showed all to be anaplastic and to produce liver micrometastases. However, more extensive abdominal and liver metastases were observed in the nude mice injected with HT-29 cells, and some of these metastases had morphologic features of moderately well-differentiated epithelium. These results indicate the usefulness of the HT-29 tumor cell line as an experimental model of metastasis from a human colonic adenocarcinoma. More... »
