MERFISH Enables Mapping of Cellular Diversity with Spatial Context at Subcellular Resolution

The brain, a lung, a tumor: each contains a complex array of cell types arranged in an intricate spatial pattern that is critical to their role within the tissue. The recently developed multiplexed error-robust fluorescence in situ hybridization (MERFISH) method provides information about gene expression at subcellular resolution and reveals cell type, state, and cell-cell interaction by quantifying the expression and exact location of hundreds to thousands of transcripts within intact tissues.
