We investigate cellular and molecular mechanisms underlying the development of the nervous and skeletal systems during embryonic development. Specifically, we seek to uncover the gene regulatory networks responsible for lineage segregation and specification of embryonic epithelia, such as the premigratory neural crest and the somite. In addition, we investigate cell migration and patterning of nascent structures such as ganglia and muscles and aim at understanding the relationship between specification and the control of subsequent cellular migrations.
- The mechanism of delamination of neural crest progenitors from the dorsal neural tube.
- Lineage specification of neural crest progenitors into neural and melanocyte derivatives.
- The role of Foxd3 in fate descisions taken by neural crest progenitors.
- The mechanisms underlying the termination of neural crest production.
- The role of the orientation of cell divisions in fate segregation of dermomyotome progenitors.
- A gene regulatory network underlying the segregation of muscle and vascular fates from the lateral dermomyotome.
- The role of Sonic hedgehog in the transition from muscle differentiation into growth.
