On-demand workflow design for image processing and analysis
Probe: Mecanosensor
Quantitative measurement of intracellular forces on living cells, but also within tissues (Drosophila, pupae, mouse intestines). Mechanotransduction, micro-nanorheology. High-resolution fluorescence imaging using remote focusing coupled with force measurements.
Compression force measurements
STED correlative imaging with molecular dynamic and interaction (FCS-FLIM-FRAP-FRET) on thin, thick samples
Light-sheet imaging of fixed and live samples. We can afford (cells, IPS, organoïds, hydra, fish, human tissues) because the microscope is installed in Biology Safety Level 2
Low signal fast live imaging at nano-scale level (Airy / Fast Airyscan , Live-3D-STED, Live-3D-SLMN)
Cell-biology expertise: providing cells(epithelial, glial, neuronal) and organoïds, labelling (transfections or probe-Test), and imaging for physicist, chemist that would like to test a prototype. Including : Guidance on super-resolution modalities (collaboration) : from system choice (SIM-STED-STORM) to images processing and data analysis (tools development).
Functional microscopy at the molecular, cellular, and tissue levels (FLIM-FCS, FRET, FRAP, laser ablation)
Correlation microscopy between super-resolution acquisition and collagen harmonic signalling
Super-resolution acquisition coupled to high-end atomic force microscopy
Light microscopy enables biosensors to be used to characterize the cellular environment (pH, ROS, calcium, etc.) in order to highlight differences between populations or identify heterogeneities within tissues or cells themselves. Cytometry allows multiparametric analyzes offering the possibility of measuring several activities simultaneously cell by cell. It is thus easy to compare the results obtained, to deduce their interdependence or not, which makes it an essential tool for the study of cell signaling.

Depending on the speed and resolution need for your live imaging project , the IGBMC platform propose different imaging systems equipped with an environmental chamber. Wide-field triggered Zeiss AxioObserver system will allow long term analysis of cell motility, wound healing application, Long-term observation of multi-labelled living cells, intracellular dynamics processes analysis (Calcium, ratiometric FRET imaging, vesicles )…High spatial 3D resolution imaging of living cells or tissues is possible on 1 point scanning (Leica TCS SP8X) or on 2 spinning disk microscopes (Yokogawa CSU-X1 or CSU-W1 scanning head) for fast acquisitions with reduced photobleaching. Live-SR modules are available on our 2-spinning disk systems enabling live Super-resolution up to 105 nm at high speed with no specific fluorophores required. 1 TIRF system equipped with a EM-CCD camera allows super resolution imaging along the optical axis (~100 nm) so imaging of membrane processes, such as receptor-ligand interactions, endocytosis, viral infection, or cell adhesion to surfaces.
2 new systems will be installed at the IGBMC platform in Spring 2025, opening up new possibilities for live imaging : 1 Lattice lightsheet will allow dynamic imaging of full sample volumes (cells, spheroids, organoids, zebrafish/c-elegans/drosophilia embryos…) with high temporal and spatial resolution and next to no phototoxicity and bleaching; 1 lattice SIM system will allow cellular, subcellular, and even sub-organelle structures in living specimens imaging in 2D and 3D with high speed, resolution below the diffraction limit (120nm, 60nm with processing) , with no need of specific fluorophores. Highest super resolution live imaging also available at our neighbored FBI Alsace Node “Plateforme Imagerie In Vitro” at INCI with the Leica Steallris STED with TauSTED and Falcon lifetime imaging option.
