Hotel Description

The Cell Observatory houses cutting-edge bio imaging technology and other facilities, aimed at visualizing the dynamic structures of life – from molecule to cell to organism. It is located in the new Gorlaeus building of Leiden University and serves as  a meeting place and shared facility for scientists from different institutes of the Faculty of Science, fostering interdisciplinary collaboration. The goal of research at the Cell Observatory is to visualize and comprehend the dynamics of the living cell down to the molecular level, because understanding of these fundamental mechanisms of life is essential for progress in tackling disease.

This group participates in NL-BioImaging AM (http://www.eurobioimaging.nl).

Expertise and Track Record

43500985032 High Resolution Analysis of Cell Fate Decisions in Totipotent Cells with K. Boutilier (Wageningen University). 43500984123 Profiling the Duchenne Brain Transcriptome using Single Cell RNA-sequencing with A. Mahfouz (Leiden University)

The Cell Observatory has unique and long-term experience in high throughput high-end microscopy using automated live cell time-lapse confocal microscopy in combination focused RNAi/compound screening strategies. It has world leading expertise in the application of fluorescent protein biosensors for cell signaling pathways using BAC-GFP transgenomics approaches and application in RNAi screening and drug safety assessment. Moreover, the application of high throughput phenotypic screening in complex 3D organoids and zebrafish embryos is well established.
