Differentiation of monkey embryonic stem cells into hepatocytes and mRNA expression of cytochrome p450 enzymes responsible for drug metabolism: comparison of embryoid body for...January 21, 2010 12:38 pm | by Biol Pharm Bull | Articles | Comments
We investigated the effects of embryoid body (EB) forming conditions on the expression of hepatocyte marker genes such as alpha-fetoprotein, albumin and CYP7A1 in cells cultured on Matrigel-coated plates for 15 d. The expression levels of hepatocyte marker genes in the cells...
