Pooled CRISPR screens with joint single-nucleus chromatin accessibility and transcriptome profiling
摘要
Pooled single-cell CRISPR screens have profiled either gene expression or chromatin accessibility but not both modalities. Here we develop MultiPerturb-seq, a high-throughput CRISPR screening platform with joint single-nucleus chromatin accessibility, transcriptome and guide RNA capture using combinatorial indexing combined with droplet microfluidics to scale throughput and integrate all three modalities. We identify key differentiation genes in a rare pediatric cancer and establish ZNHIT1 as a potential target for cancer reprogramming therapy.
