Creatine transporter mRNA expression in the developing spiny mouse placenta, brain and heart. A, Placental CrT mRNA expression; B, Brain CrT mRNA expression; C, Heart CrT mRNA expression. All mRNA data are normalized to 18S and shown relative to 37 days gestation. Data points not sharing the same symbol indicate expression is significantly different to all others (p < .05). Mean ± SE. GA, gestational days; PN, postnatal days.
