Integration and Validation of RNA ISH Multispectral Imaging and Analysis Protocols into a Core Environment

摘要

Identification of biomarkers is a major goal of personalized medicine. Large transcriptome screens have identified new targets and molecular signatures for disease sub-types. However, tissue spatial information, which fundamentally alters in vivo cell behavior and gene expression, is lost. To understand spatial context and validate bulk tissue screens, most researchers rely exclusively on antibodies and immunostaining assays. Unfortunately, this is either not the appropriate choice for some targets, such as long non-coding RNAs, or it is not feasible because no reliable antibodies exist. To address these issues, we have established an alternative work-flow incorporating RNA in situ hybridization (CISH and FISH), whole slide and/or multispectral scanning and image analysis.
