Enzymatic characterization of confluent cultures. Specific activity of maltase (A) over the age of a confluent culture of jejunocytes at the first passage, (B) over the increasing passage number of confluent cultures of jejunocytes (open boxes) compared to the same culture during 7-days in a inosin-containing glucose-deprived culture medium (black boxes) or (C) maintained 7 days in a medium added of sodium butyrate (1–2 mM). Results are expressed as mean values ± SD for three culture samples. ND =not detected, ***p < 0.001.
