Researchers at UCSF have developed XYZeq, a method for coupling a cell’s spatial location with single-cell sequencing. Single-cell genomic techniques have emerged as powerful approaches to further our understanding of disease states and cellular heterogeneity. Single-cell imaging methods gain spatial information, but lack throughput and detailed transcriptomic information. Current single-cell sequencing approaches require dissociation of cells during preparation, as a result cannot record a cell’s physical location. UCSF researchers eliminate this step using XYZeq, a new scRNA-seq process that incorporates the benefits of single-cell imaging techniques with single-cell sequencing, without an imaging step. XYZeq simultaneously discerns the location and gene expression of a single cell residing within a complex tissue microenvironment. The technology has been validated in a laboratory setting.
