Project description
Microscopy-assisted investigation of developmental plasticity
During development, genetic and epigenetic factors interact with environmental cues to shape the organism's phenotype. This ability of the embryo to adapt is known as developmental plasticity but our understanding of the process is limited. Funded by the European Research Council, the SmartMic project aims to address the limitations of existing microscopy tools that cannot systematically image and analyse embryos in real time. Researchers will develop a novel microscopy platform with adaptive illumination and detection that makes it possible to focus only on relevant data. By automating the process and analysing multiple samples, this smart microscopy concept will enable large-scale comparative studies in real time, advancing our understanding of embryonic development.
Objective
"Fluorescence microscopy is a key technology in our quest to understand fundamental developmental processes of life. High-resolution images recorded in intact, living organisms deliver insights into the complex interplay of molecules, cells and tissues in real time. Even though the resolution of microscopes has been pushed beyond the diffraction limit, providing important insights into the inner workings of single cells, we still lack an understanding of plasticity in development: How does one embryo differ from another and how can we describe the ""average"", stereotypic embryo?
To address this long-standing multi-disciplinary challenge, we propose to develop an entirely novel microscopy hard- and software platform to systematically image and analyze embryos in real time. We will design and assemble a fast and flexible multimodal light-sheet microscope (SPIM) with adaptive illumination and detection from multiple sides. A fundamentally new concept of this proposal is the ability to adaptively change the recording's spatial and temporal resolution during the experiment: The microscope learns to acquire only the data of interest. Using a high-throughput sample feeder, many samples can be automatically pumped through the microscope and imaged within seconds for large-scale comparative developmental studies. Real-time processing will dramatically reduce the size of the data stream and thus, provide for the first time a platform to collect data from hundreds of samples. At the same time, by establishing a model for the observed embryo, we will integrate information from multiple samples to draw statistically relevant conclusions.
Our ground-breaking concept of smart microscopy speeds up the acquisition, reduces the amount of data and limits photo-toxicity. It enables us to address fundamental questions in embryonic development that are out of reach by traditional methods. Smart microscopy will open up a new field of research: systematic real-time developmental biology."
