Research - The CP²C group is interested in understanding mechanisms of cell plasticity contributing to normal development and disease progression. Our work focuses on phenotypic plasticity driven by epithelial-mesenchymal transition and ciliary signaling in cellular ecosystems. We use cutting-edge imaging and genomic technologies together with innovative animal models, organoids and chemical tools to map and understand cell state transitions in normal and disease states ranging from ciliopathies to cancers.

Additional background - Tissue development and disease progression relies on distinct cell types that communicate and transit in distinct cell states in cellular ecosystems. Epithelial-Mesenchymal Transition is a developmental program that can be activated to induce cell state transition in epithelia and carcinomas. It regulates the formation of primary cilia and thereby cell motility and stemness. Primary cilia act as cell signaling hubs in cells where signaling components are processed to regulate autocrine and paracrine signaling in cellular ecosystems in normal and disease states.

Past accomplishments -
Our work revealed two new ciliopathies (i.e. developmental disorders caused by abnormal cilia, STAR and AL KAISSI syndromes). We discovered a role for primary cilia downstream of EMT programs in normal breast development and in the formation of a subtype of breast cancers (i.e. claudin-low).
