Chromosomes of prophase nucleus of an embryo exposed to normoxia. Embryos were collected, and stained with DAPI and the mAb414 to recognize nuclear pore complex. Spinning disk confocal microscopy was used to obtain Z-stack images of the prophase nucleus. The movie (QuickTime Player 7.0.3) depicts a 9.2 μm region that includes the nucleus cross-sectioned every 0.2 μm for a total of 46 cross sections. DAPI and mAb414 images were merged to evaluate prophase chromosome location relative to the nuclear membrane.

Chromosomes of prophase nucleus of an embryo exposed 30 minutes of anoxia. Embryos were collected, and stained with DAPI and the mAb414 to recognize nuclear pore complex. Spinning disk confocal microscopy was used to obtain Z-stack images of the prophase nucleus. The movie (QuickTime Player 7.0.3) depicts a 9.2 μm region that includes the nucleus cross-sectioned every 0.1 μm for a total of 92 cross sections. DAPI and mAb414 images were merged to evaluate prophase chromosome location relative to the nuclear membrane.

Chromosomes of prophase nucleus of an embryo exposed 24 hours of anoxia. Embryos were collected, and stained with DAPI and the mAb414 to recognize nuclear pore complex. Spinning disk confocal microscopy was used to obtain Z-stack images of the prophase nucleus. The movie (QuickTime Player 7.0.3) depicts an 8.4 μm region that includes the nucleus cross-sectioned every 0.2 μm for a total of 42 cross sections. DAPI and mAb414 images were merged to evaluate prophase chromosome location relative to the nuclear membrane.

Chromosomes of prophase nucleus of an embryo exposed to normoxia. Embryos were collected, and stained with DAPI, mAb414 to recognize nuclear pore complex and anti-gamma tubulin to recognize the centrosome. Spinning disk confocal microscopy was used to obtain Z-stack images of the prophase nucleus. The movie (QuickTime Player 7.0.3) depicts a 10.0 μm region that includes the nucleus cross-sectioned every 0.2 μm for a total of 50 cross sections. DAPI, mAb414 and anti-gamma tubulin images were merged to evaluate prophase chromosome location relative to the nuclear membrane.
