Monitoring early embryogenesis with single-plane illumination microscopy — •Philipp Struntz, Rolf Fickentscher, and Matthias Weiss — Experimental Physics I, University of Bayreuth, Germany

Single-plane illumination microscopy (SPIM) is a fluorescence-imaging technique that combines rapid widefield detection with optical sectioning. Due to a reduced phototoxicity induced by bleaching, SPIM is capable of providing a long-term, three-dimensional time-resolved in vivo imaging of specimen. We have built and automated a SPIM-setup specifically designed for imaging eggs of the nematode Caenorhabditis elegans in the early stages of embryogenesis. With the obtained time-lapse images it is possible to track cell positions within the developing embryo to get information about the spatiotemporal development of tissues. Based on this, we have designed a simple model that is capable of explaining experimental observations during the first stage of embryogenesis.
