Abstract

Human colorectal adenocarcinoma tumor (CW2) cells were cultivated in RPMI 1640 media containing 0-7.5 mM aspirin and 10% fetal bovine serum for the production of carcinoembryonic antigen (CEA). By adding aspirin to the media, the production of CEA per cell increased by up to one hundred fold compared to cultivation in normal media containing no aspirin, even though the total cell concentration decreased with the increase in aspirin in the media. The production of CEA was also investigated for CW2 cells cultured on silk fibroin, poly(gamma-benzyl-L-glutamate) and poly(gamma-benzyl-L-glutamate)/poly(ethylene oxide) diblock copolymer films prepared by the Langmuir-Blodgett and casting methods. The highest production of CEA per cell was observed for the CW2 cells on poly(gamma-benzyl-L-glutamate) and its diblock copolymer films prepared by the Langmuir-Blodgett method in the medium containing 5 mM aspirin after 168 hr of inoculation. This originates from the fact that the cell density on the films in the medium containing 5 mM aspirin was the lowest under these conditions. It is suggested that CW2 cells produce CEA more effectively when the cell growth is suppressed by addition of toxic chemicals such as aspirin or by culture on unfavorable films for cell growth.
