SLC16A2 and fetal growth restriction: The mean percentage area of cortical plate immunostaining after correction for relative cell number was 4.7±1.5% (mean±s.e.m.; 0.2±0.07 relative to AGA) in the IUGR group compared with 23.3±8.1% (1±0.3 relative to AGA) in the AGA group (P<0.05), which represents approximately a fivefold decrease in MCT8 expression with IUGR (Fig. 2).
