Figure 3From: Temporal expression patterns of insulin-like growth factor binding protein-4 in the embryonic and postnatal rat brainTemporal expression of IGFBP-4 mRNA in embryonic rat brains. The level of IGFBP-4 mRNA in embryonic brains changed from days E10.5 to E18.5 and reached a peak at days of E13.5 and E14.5. RQ of IGFBP-4 mRNA in the brains before birth was significantly higher than that at P0 (*P < 0.05).Back to article page
