Fig. 9: Expression of Slc22a2 (Oct2), Slc22a6 (Oat1), and Slc22a8 (Oat3) expression in organoids and adult kidneys.

a Heatmap of Oct2, Oat1, and Oat3 expression in organoids and adult kidneys. b Quantitative PCR confirm that Oct2, Oat1, and Oat3 are not expressed in organoids. Gene expression is relative to undifferentiated embryonic stem cells (ESCs). Asterisk (*) indicates that expression is significantly different (p < 0.05) from adult kidneys, as determined by t test. n = 3. Error bars represent standard deviation.
