Figure 2
Pronuclear formation in cat oocytes activated by electroporation (EP), thimerosal/DTT (Thi/DTT), SrCl 2 and Na+-free medium (Na+-free) with or without 4-h incubation in cycloheximide (CHX) and cytochalasin B (Cyto B). The asterisk indicates a significant difference (P < 0.05) between frequencies of pronuclear formation achieved with and without CHX/Cyto B supplementation. Different lowercase letters indicate significant differences between treatments without CHX/Cyto B supplementation (P < 0.05); different uppercase letters indicate significant differences between treatments that were followed by CHX/Cyto B incubation (P < 0.05).
