Pseudocleavages and nuclear migration prior to the first cell division. Selected images from digital time-lapse video recordings of living M. incognita embryos progressing through the early development. Images on (a) illustrate the pseudocleavages, high cytoplasmic activity and membrane ruffling that happen during the first cell cleavage. Images on (b) illustrate nuclear migration before the first cellular division. Both sets of images come from series in which images were taken every 30 min. The number in each picture is the time in hours after the first picture was taken. No cell divisions take place during either of these activities. Bar = 25 μm
