A major challenge in neuronal stem cell biology lies in characterization of lineage-specific reprogrammed human neuronal cells, a process that necessitates the use of an assay sensitive to the single-cell level. Ssingle-cell gene profiling can provide definitive evidence regarding the conversion of one cell type into another at a high level of resolution. The protocol we describe uses Fluidigm Biomark dynamic arrays for high-throughput expression profiling from single neuronal cells, assaying up to 96 independent samples with up to 96 quantitative PCRpcr (qPCRpcr) probes (equivalent to 9,216 reactions) in a single experiment, which can be completed within 2-3 d. protocol enables simple and cost-effective profiling of several hundred transcripts from a single cell, and it could have numerous utilities.
