Serpina3 modulates neuronal cell fate determination (scRNA sequencing)

Purpose: To better understand how Serpina3 modulate cortex enpansion and folding. We performed single cell sequencing to reveal the change of cell types in single cell level. Method: Single cell isolation was prepared from P0 telencephalic tissue of wild-type (WT) and serpina3f/+;Nestin-Cre mice. The fragmented cDNAs containing barcode and UMI sequences was built the library. Agilent 2100 Bioanalyzer was used to quality controlled and quantified. Single cell RNA-sequencing analysis was used by the Illumina platform in Annoroad Genomics. Results: Clustering and labeling of these cells visualized on a t-SNE plot between the wild-type (WT) and Serpina3f/+;Nestin-Cre mice brain cortex. Specific layer neurons were increased in Serpina3 knock in mice. Conclusions: Single cell RNA-seq data would provide an overall understanding how SERPINA3 gene contribute to generation of cortical expansion and folding in mice. Single cell isolation of P0 wild type (WT) and SERPINA3f/+;Nestin-Cre mice were generated by deep sequencing, in triplicate, using Illumina.
