Figure 5: Quantification of Igf2 P0 and Igf2as expression levels in wild-type placentas. Quantifications of Igf2 P0 (P0) and Igf2as transcripts levels in wild-type placenta (WT) at different embryonic stages (E12, E14, E16, and E19). The results are expressed in relative expression. Each bar represents the mean of three samples analyzed in triplicate. The standard deviation for each bar is indicated by error bars. .
