Figure 3. Microinjection of CSN3 or CSN5 dsRNA into GV oocytes resulted in MI arrest.

Microphotographs of oocytes (A) and maturation rates (B) after in vitro culture for 16 h. Control and buffer-injected groups were MII after 16 h in culture, but injected oocytes were arrested at the MI stage. Bars = 50 µm. Asterisks indicate statistically significant differences compared to that of control or buffer group (p<0.05).
