Single-cell RNA-seq of spiral ganglion neurons from wildtype and Vglut3-/- mice

Molecular heterogeneity among spiral ganglion neurons (SGNs) in the mouse cochlea was investigated in two genetic backgrounds: 1) wildtype, 2) Vglut3-/-, which lack inner hair cell-driven glutamatergic activation of SGNs. Overall design: Individual spiral-ganglion neurons expressing the fluorescent reporter tdTomato were dissociated and manually placed into PCR tubes; single-cell libraries were made by the Smart-seq2 approach; sequencing was done using the NextSeq platform (Illumina) at an average read depth of 4.5 million; bioinformatic analysis was conducted in R. Genotypes: bhlhb5::cre/+; Ai14/+ (wildtype) and bhlhb5::cre/+;Ai14/+; Vglut3-/- (Vglut3-/-). Age: P25-P27
