Transcriptional networks and neural differentiation

 

 

Our research projects are devoted to the molecular mechanisms that regulate cell state during the formation of embryonic spinal cord and rhabdomyosarcoma tumours. To do so, we focus on the state dynamics generated by transcription factors of the PAX family and we use stem cell-derived organoids as study models
