简介：
Overview
This work describes a semi-high-throughput protocol that allows simultaneous 3D time-lapse imaging of embryogenesis in 80–100 C. elegans embryos in a single overnight run. The ability to collect data for large numbers of developing C. elegans embryos opens up a new range of experiments, including quantitative analysis of developmental events.
