Ferretti Group: Lineage Choice and Mesodermal Competence
"Our aim is to understand how cell signaling pathways and transcription factor networks interact to guide mesodermal fate
The main goal of the Ferretti group is to identify and dissect the gene regulatory networks that spatially and temporally control mesoderm specification. Over the past years, much effort has been devoted to the characterization of extrinsic signaling controlling mesoderm differentiation; however, it remains unclear what the molecular mechanisms generating the different mesodermal types are. Knowing these mechanisms is critical for establishing efficient methods to direct the fate of pluripotent cells towards specific mesodermal progenitors, making the differentiation process more specific and robust. To achieve this goal the group focuses on the following specific questions.
- How does the duration of the signal cues affect mesodermal fate?
- How do genes conferring positional information guide mesodermal choices?
- How does the primed state of the epiblast influence mesoderm differentiation?
Our long-term goal is to generate robust models for mesoderm differentiation that will help in conceiving innovative protocols for hESCs mesoderm differentiation.
