GSE99757: Low-input and multiplexed microfluidic assay reveals epigenomic variation across cerebellum and prefrontal cortex

Bulk RNA sequencing

There has been an extensive effort underway to profile epigenetic features at the genome-wide scale using primary ex vivo tissues. Cell-type specificity of epigenomes calls for enrichment to obtain a homogenous cell population from a small quantity of tissues. Thus technologies that permit both ultralow input and high throughput are desired for profiling an array of histone marks. Here we demonstrate a simple microfluidic technology, SurfaceChIP-seq, for profiling genome-wide histone modifications using as few as 30 cells per assay and with up to 8 assays running in parallel. We applied the technology to study epigenomic landscapes in neurons and glia in prefrontal cortex and cerebellum of mouse brain. The data revealed extensive epigenomic difference in the two regions on important functional elements such as promoters and enhancers. SOURCE: Chang Lu (changlu@vt.edu) - Chang Lu Virginia Tech
