Spatial information from NICHE-seq

Single-Cell Genomics Immune functions depend on the interactions of heterogeneous cells in a range of microenvironments in the body. Although information regarding immune cell function has been collected using single-cell RNA-sequencing methods, these techniques have traditionally lacked spatial information. Medaglia et al. describe NICHE-seq, a technique that allows the sorting and analysis of cells from within visually selected territories in transgenic mice that express photoactivatable green fluorescent protein. The method successfully identified T and B cell-specific niches in mouse lymph nodes and spleens after virus infection. The approach will allow us to bridge the gap between cellular and spatial information in studies of organs. Science , this issue p. [1622][1] [1]: /lookup/doi/10.1126/science.aao4277
