Evaluation of a novel choanoid fluidized bed bioreactor for future bioartificial livers

Figure 3 Changes in alanine aminotransferase in encapsulated hepatocytes in medium (n = 5). Levels are given as U/L (mean ± SD), (gray bar) encapsulated in alginate/chitosan (AC) microcapsules in static conditions; (white bar) encapsulated in AC microcapsules and placed in the choanoid-fluidized bed bioreactor. Student’s t test (^aP < 0.05; ^bP < 0.01, static vs fluidized). NS: Not significant; ALT: Alanine aminotransferase.
