Sfmbt2 expression in biparental and uniparental embryos during preimplantation development. (a) Confirmation of differential expression of Sfmbt2 in androgenetic (A), gynogenetic (G), and biparental reconstituted (F) blastocysts. Data were obtained by the QABD method (see Experimental procedures), and are expressed in units of counts per minute (cpm) of probe bound on dot blots. (b) Expression of control Eef1a1 in the three types of embryos, also produced using the QABD method. (c) DNA array-based expression data for Sfmbt2 during mouse preimplantation development. Data were compiled from Zeng et al., 2004 and depict the average fluorescence intensities from four hybridized arrays per stage. Stages shown correspond to one cell (1C), 2 cell (2C), 4 cell (4C), 8 cell (8C), blastocyst (Bl). Expression from 1C to 8C likely represents basal level of transcription.
