Abstract

We plan to use state-of-the art mass spectrometry-based proteomics, fluorescence microscopy and machine learning to understand the molecular basis of cell competition. Cell competition is a phenomenon that results in the elimination of less fit cells from a tissue, and is a critical process in development, homeostasis and disease.
