The Z03 Central Project provides access to screening approaches including CRISPR-Cas9 and RNAi screening in cell culture models, as well as time- and spatially-resolved CRISPR and RNAi screening in Drosophila. The Z03 project generates cell lines in which Wnt signaling pathway components are endogenously modified by fluorescent proteins using genome editing to perform quantitative analysis using advanced imaging techniques. The platform supports screening procedures in cell culture models and generates a collection of Drosophila CRISPR lines for tissue-specific in vivo studies.
