Descripción
Sumario:Two human colon cancer xenografts (EC and AC) were established in tissue culture only after long-term passage in nude mice. Earlier attempts to establish cell lines were unsuccessful. The epithelioid cells retain their tumourigenicity after in vitro growth, giving rise to tumours with a take rate of 60-80%. After reimplantation, the xenografts retain a similar morphology to that of the original human tumours. Both cell lines show human karyology. Comparative mapping of Concanavalin-A acceptor glycoproteins provides a fingerprint characteristic of each cell line. These glycoprotein patterns are similar to those shown by HT-29, an established colon cancer cell line. IMAGES:
