Single-Cell mRNA-Seq of In Vitro-Derived Human Neurons Using Smart-Seq2

Abstract

Single-cell mRNA sequencing can dissect heterogeneous cell populations as it can identify cell types and cellular states based on their unique transcriptional signatures. We use fluorescence-activated cell sorting (FACS) to isolate individual cultured neurons derived from human-induced pluripotent stem cells (hiPSCs) followed by polyA-based Smart-Seq2 RNA sequencing to analyze the single-cell transcriptional profiles. We provide protocols and guidelines on dissociation, cell selection, and library preparation that can be readily adapted to other cell types or tissue samples.
