Project
Our project aims to obtain a collection of quantitative information about cell division dynamics in early
Caenorhabditis elegans embryos when each of all essential embryonic genes in all essential genes is silenced
individually by RNA interference (RNAi).
The information is obtained by combining four-dimensional differential interference contrast (DIC) microscopy and
computer image processing (Hamahashi et al. 2007). The information collection provides novel opportunities for
developing quantitative and computational approaches towards understanding animal development.
