THE LAB
Our research focuses on the molecular mechanisms underlying the multiple roles of morphogens during nervous system development. Our
lab is part of the
Centre for Neuroscience of Sorbonne University (NeuroSU), which hosts many other research teams devoted the study of the nervous system from its development to neural plasticity, activity and pathology. Our research center is affiliated to the Inserm (French National Institute for Medical Research), the CNRS (National Center for Scientific Research) and the Sorbonne University.

OUR RESEARCH
How do morphogenic signals control distinct responses during neural development?
During embryonic development, the formation of the brain by the generation, differentiation and
finally the precise connection of new neurons is controlled by many molecular factors. Amongst
these factors, extracellular secreted molecules, called morphogens, instruct the shape of the nervous
system. During neuronal differentiation, cells change from a proliferative state to acquire cell
identity, to perform migration and finally to grow axons and connect to other cell types. Thus, cells
need to change their responses to their environment to achieve the correct behavior. Our research
addresses fundamental questions on how a single (and then multiple) morphogenic signal(s) act at
different steps of neuronal development to induce these different responses. We use the murine and
human developing cerebral cortex as a model.
Experimental approaches
- In vitro primary cultures of cortical progenitors and neurons
- Microfluidic chambers
- In utero electroporation
- 3D imaging of embryos
- Molecular Biology such as single cell RNA-seq
- Biochemistry
Overall, our projects aim to determine the molecular and temporal bases for morphogenic response
modulations during differentiation during the development of the nervous system.
