Mapping Polycomb-repressed domains in the bithorax complex using in vivo formaldehyde cross-linked chromatin.

abstract：:Subsets of long-lived, tumor-initiating stem cells often escape cancer therapies. However, sources and mechanisms that generate tumor heterogeneity and drug-resistant cell population are still unfolding. Here, we devise a functional reporter system to lineage trace and/or genetic ablate signaling in TGF-β-activated sq...
