Comprehensive catalog of dendritically localized mRNA isoforms from sub-cellular sequencing of single mouse neurons

To compare the RNAs present in dendrites and somas of individual neurons, we manually separated the dendrites and soma of primary mouse hippocampal neurons using a micropipette and performed RNA-sequencing on each subcellular fraction such that we obtained the subcellular transcriptomes of the same cell. Overall design: 16 individual neurons were collected and dissected (yielding a total of 32 soma and dendrite samples) from multiple cultures across multiple days. ERCC spike-in control RNA was added to each sample.
