FIG. 2.

Decreased expression of GCN5 acetyltransferase in parthenogenetic morulae and blastocysts. Double immunostaining against GCN5 and Cdx2 revealed significantly decreased GCN5 expression (indicated by arrows) throughout the whole parthenogenetic embryos (including both the outer Cdx2+ and inner Cdx2- blastomeres) compared with control embryos at both the morula (A) and blastocyst (B) stages. Scale bars: 20 μm.
