The dynamic nature of chromatin and transcription plays a critical role in normal differentiation and is expected to contribute to tumor evolution. Studying chromatin heterogeneity with single-cell resolution is mandatory to understand the role of epigenetic plasticity in cancer. Here, we describe a droplet microfluidics system that enables the profiling of chromatin marks of individual cells with an average coverage of up to 10,000 loci per cell. In patient-derived xenograft (PDX) models of bre...

How this grade was computed

The insufficient grade is a transparent weighted average. Each metric below scored from 0–100% against the published ChIP-seq thresholds, weighted by its importance; nothing is hidden or subjective.
