CIL:35126

This time-lapse series illustrates the early division up to the four-cell stage of a C. elegans embryo depleted of ufd-1 through RNAi. The first C. elegans embryonic division of the P0 zygote is asymmetric and generates an anterior AB cell, and a smaller posterior P1 cell. These cells have different developmental fates and division timing, with AB dividing approximately 2 min before P1. Time-lapse differential interference contrast (DIC) microscopy identified that downregulation of cdc-48, ufd-1, and npl-4 increases the cell division delay of P1 in comparison to AB, leading to a prolonged three-cell stage. The series corresponds to experiments shown in Fig. 1B and Movie 4 of Mouysset et al. Movie is CIL 25631 and original data file is CIL 35126.
