title: Hepatic differentiation of human adipose tissue-derived mesenchymal stem cells and adverse effects of arsanilic acid and acetaminophen during in vitro hepatic developmental stage.
abstract: In the present study, we differentiated hepatocyte-like cells (HLCs) from human adipose tissue-derived mesenchymal stem cells (AT-MSCs). The hepatic differentiation was confirmed by increases in hepatic proteins or genes, the cytochrome P450 (CYP) activities, albumin secretion, and glycogen storage. To determine the developmental toxic effect of arsanilic acid (Ars) and acetaminophen (AAP) on the hepatic development, the differentiating cells were treated with the test chemicals (below IC12.5) from day 4 to day 13. The enzymatic activities of lactate dehydrogenase (LDH), alanine aminotransferase (ALT), and aspartate aminotransferase (AST) did not significantly differ in response to Ars treatment. AAP treatment increased the activities of all enzymes in a dose-dependent manner, significantly at concentrations of 2.5 and 5 mM of AAP. On the expressions of hepatic genes for Ars, the expressions were significantly inhibited by more than 0.5 mM for Albumin (ALB), but only 2.5 mM for α-feto protein (AFP). In the AAP-treated group, the expressions of ALB and AFP were significantly decreased at the concentrations exceeding 0.625 mM. The activities of CYP3A4 were not changed by both treatments. The activities of CYP1A2 were increased by AAP, whereas it was decreased by Ars treatment. In conclusion, AAP could cause serious adverse effects during the hepatic development as compared to Ars.
