Title	Deciphering lineage specification during early embryogenesis using multi-layered proteomics
Description	Gastrulation is a critical stage of embryonic development during which the three germ layers are established. Deciphering the molecular mechanisms underlying this process from a protein perspective remains a significant challenge. To address this, we employed a multilayered mass spectrometry-based proteomics approach to investigate the global dynamics of (phospho)protein expression during differentiation of ESCs towards gastruloids – an in vitro model of gastrulation-stage embryogenesis. Our findings revealed that many proteins exhibited temporal expression during gastrulation with unique expression profiles corresponding to the three germ layers, which we also validated using an ultra sensitive single cell proteomics approachtechnology. Additionally, we profiled enhancer interaction landscapes in ESCs and gastruloids using p300 proximity labeling, which revealed numerous gastruloid-specific transcription factors and chromatin remodelers. Subsequent degron based perturbations combined with scRNA-seq revealed a critical role for Zeb2 in regulating mouse and human somitogenesis. Overall, this study provides a rich resource for developmental and synthetic biology communities endeavoring to understand mammalian embryogenesis.
