First Divisions in Early Embryos and Chromatin Dynamics in Lamin Mutants
To image early cleavages and chromatin dynamics, it is convenient to use histone H2B fused to GFP or lamin::GFP. Time-lapse movies can be obtained using conventional confocal microscope systems and their included software. Early embryos dissected from transgenic hermaphrodites are placed with egg salts on agar pads (e.g., Live Imaging of Caenorhabditis elegans: Preparation of Samples). Chromatin dynamics can be followed easily, and wild-type embryonic cells can be compared with mutants or RNAi-treated embryos [for normal lamin staining, see Fig. 1 and for chromosomal defects in lamin(RNAi) embryos, see Movie 1 ].
