Temporal expression patterns of four cx mRNAs during oogenesis. The expression levels of cx30.9 (A), cx34.3 (B), cx43.2 (C), and cx44.9 (D) were normalized to ef1a (inset of panel A). PN, perinucleolus stage follicles; CA, cortical alveolus stage follicles; LD, lipid droplet stage follicles; VIT, mid-vitellogenic stage follicles; MAT, preovulatory, maturing stage follicles. Bars not sharing the same letter are significantly different (P < 0.05; n = 4/group of PN-, CA-, LD-, and VIT-stages, n = 3/group of MAT-stage, mean ± SEM).
