Abstract
The maintenance of high levels of two liver-specific mRNAs in cultured hepatocytes was achieved in a serum-free hormonally defined cell culture medium. However, this maintenance of liver-specific mRNA levels did not correlate with the level of transcription of the genes but was apparently due to increased stabilization of the tissue-specific mRNAs. The mRNA stabilization did not occur in serum-supplemented medium. In both defined and serum-supplemented medium, actin and tubulin mRNAs were also greatly increased, in both cases predominantly if not entirely due to increased mRNA stability.
