  1. Highlights:
  2. 1. The majority of porcine oocytes achieve nuclear maturation at 33 h of IVM and proceed with cytoplasmic maturation from 33 h to 42 h
  3. 2. Porcine oocyte during 33 h of IVM is able to sustain IVF embryo development, and further cytoplasmic maturation is indispensable for development of SCNT and PA embryos
  4. 3. 18 differentially expressed proteins between oocytes during 33 h and 42 h of IVM are identified by mass spectrometry
