Postdoc position in Marseille - Biochemical and mechanical guidance of migration in single cells... (BB-C8DFA)
Trouvé dans: Talent FR
Description:Host laboratory and collaborators / LAI / / IBDM - CPT - LAI / KeywordsMigration, guidance, single cells, cell aggregates, cell and tissue mechanics, gradients, microfluidics, live imagingObjectivesThe objectives will be to (i) characterize the migration of single cells versus external guiding cues, either mechanical (adhesion patterns, confinement) and biochemical (gradient of chemokines) (ii) adapt the microfluidic system to 3D cells aggregates (few hundreds of microns size) and optimize substrate characteristics for their migration (iii) image in 2D and 3D the collective dynamics of cells within the aggregate during the migration and analyze their organization and dynamics in response to external perturbations.Expected profileThe candidate should be interested in biophysics and quantitative reductionist approaches in vitro. An experience in microscopy/image analysis and/or microfluidics and/or cell biology is valuable.2 to 5 references related to the project Beaune, G., C. Blanch-Mercader, S. Douezan, J. Dumond, D.
