Other claims from this paper (7)
- 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.
- Mechanism Nuclear degradation products were postulated to improve embryo survival, growth, and multiplication.
- Observation Nonapoptotic embryonal nuclei fluoresced strongly with DAPI.
- Observation Nuclei reacted blue with Giemsa in TUNEL-probed cells.
