Other claims from this paper (7)
- Observation Specific nuclei were eliminated during diploid parthenogenesis.
- Observation Nuclei became pycnotic and fragmented.
- Observation Tubular axial-tier cells lost interphase nucleoli before enucleation.
- Mechanism Apoptosis involved endonuclease activation and cell death.
- Method / resource TUNEL stained apoptotic nuclei red.
- Observation Nonapoptotic embryonal nuclei fluoresced strongly with DAPI.
- Observation Nuclei reacted blue with Giemsa in TUNEL-probed cells.
