Impact of hypothermic preservation of mouse kidney resident immune cells

With the growing interest in studying primary tissue samples by single cell transcriptome analysis, there is an emerging demand for a preservation strategy that enables sample transportation and storage. In this study, we describe a simple and general strategy that preserves primary tissues at hypothermic temperature. Using FACS and single-cell RNAseq, we demonstrated the effectiveness of this strategy in maintaining cell viability, cell population heterogeneity, and cell transcriptome integrity for primary tissues that underwent up to 3 days of preservation. Overall design: Examine the impact of hypothermic preservation on mouse kidney resident immune cells over up to 4 days at single-cell resolution
