Temporal expression of IGFBP-4 protein in embryonic rat brains. (A) The results of Western blot, (B) A quantification of IGFBP-4 protein achieved by densitometry of 12 experiments. The expression pattern of IGFBP-4 protein is similar to that of IGFBP-4 mRNA. The expression peak was at E13.5 (282.75% of that at P0). ★- the level of IGFBP-4 protein is significantly higher than P0 (all P < 0.05).
