Results
Specimen 5A: postnatal adult (more )
Note: Metaphase-arrested oocyte
Structure Level Pattern Image Note
TS28: primary oocyte Present Regionally restricted 5A Expression is in the cytoplasm around the spindle, especially around the equator.
Specimen 5B: embryonic day 0.5 (more )
Note: G1- phase 1-cell stage
Structure Level Pattern Image Note
TS1: 1-cell stage embryo Present 5B Expression is centrally in the cytoplasm and is excluded form the pronuclei.
Specimen 5C: embryonic day 0.5 (more )
Note: S-phase 1-cell stage
Structure Level Pattern Image Note
TS1: 1-cell stage embryo Present 5C Expression is in the cytoplasm and in the expanded pronuclei as a ring around the nucleoli.
