in all culture conditions where ht-29 cells did not differentite , the intracellular concentrations of 2 compounds which co-migrated with udp-n-acetylglucosamine and udp-n-acetylgalactosamine rose approximately equal to 10-fold at confluency and remained elevated throughout the stationary phase , whereas their concentrations remained constant and low after confluency in cells that underwent differentiation .
