We created a new multiplex fluorescent in situ hybridization (FISH) method for analyzing gene expression in preserved human tissues. This technique precisely maps single-cell RNA patterns, offering predictive gene expression signatures.

Area of Science:

  • Molecular Biology
  • Genetics
  • Biotechnology

Background:

  • Archival formalin-fixed, paraffin-embedded (FFPE) tissues are valuable for research.
  • Analyzing single-cell gene expression in FFPE tissues presents technical challenges.

Purpose of the Study:

  • To develop a robust multiplex fluorescent in situ hybridization (FISH) technique.
  • To enable single-cell gene expression analysis in FFPE human tissues while preserving microanatomical context.

Main Methods:

  • Multiplex fluorescent in situ hybridization (FISH) on FFPE human tissue sections.
  • Probing multiple unique nascent RNA transcripts for gene expression analysis.

Main Results:

  • Successful implementation of a robust multiplex FISH technique.
