Multicellular organisms and colonies under the microscope

Cells within multicellular organisms and colonies play specific,
well-defined roles. This often translates into different behaviors and
transcriptional programs being executed by cells located at different
places of the organism. Optical microscopies are able to visualize
single-cells while maintaining spatial information, and thus
constitute an optimal tool to investigate these problems. In this
talk, I will present several examples of how new microscopy
technologies can be used to understand cell motility in Myxococcus
Xhantus and chromosome organization in Drosophila embryos.
