Microscopies avancées & physiologie des tissus

Ongoing advances in optical imaging open novel possibilities for studying intact biological tissues with subcellular resolution. We develop experimental strategies for removing bottlenecks in experimental systems biology based on our expertise in nonlinear optics, tissue microscopy, image analysis, cell/developmental biology, and biophysics. Our activity consists of two complementary aspects (i) microscopy methods development including proof-of-principle studies, and (ii) studying embryonic development and tissue function using multidisciplinary approaches.

Methods: biophotonics, multiphoton microscopy, light-sheet, 2PEF, 3PEF, SHG, THG, FLIM, CARS, SIM, polarization, laser ablation, terahertz. Topics: embryogenesis, neurodevelopment, collagen, heart, cornea, extracellular matrix. Models: zebrafish, drosophila, mouse (ex vivo), tissue biopsies, cell cultures.
