Title Deciphering lineage specification during early embryogenesis in mouse gastruloids using integrative multi-layered proteomics [scRNA-seq]
Organism Mus musculus
Experiment type Expression profiling by high throughput sequencing
Summary Gastrulation is a critical stage of embryonic development during which the three germ layers are established. Deciphering the molecular mechanisms underlying this proces 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 with unique expression profiles corresponding to the three germ layers. 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.
Overall design Somitic gastruloids were generated as previously described (Protoc. Exch., van den Brink et al., Nature 2020). Somitic gastruloids expressing Zeb2-degron tag were treated with 100nM dTAG-13 or DMSO at 72 and 96h during gastruloid formation.
