Fig 2. Low Mfn2 expression attenuates the blastocyst formation rate and cleavage speed.

In T group, the cleavage speed was reduced compared with that in control group, the blastocyst formation rate was significantly reduced in the T group compared with the C group. C1 and T1: 4-cell fertilized eggs, C2 and T2: 8-cell fertilized eggs. C3 and T3: Blastocyst. Data are means ± SD of 3 separate experiments.
