The gene expression of the extracellular matrix macromolecules is critical in the analysis of various pathologies. The use of a RT-PCR directly on a fixed tissue enables the recognition of the real expressing cells for any ECM molecules together with the tissue localization. The method here described is easy to perform using the same material as for common immunostaining and the same primers used for quantitative RT-PCR. Moreover, the used primers, designed with a final amplicon that spans the exon-exon junction, allow to detect the cDNA but not the gDNA sequences.

Abstract
The gene expression of the extracellular matrix macromolecules is critical in the analysis of various pathologies. The use of a RT-PCR directly on a fixed tissue enables the recognition of the real expressing cells for any ECM molecules together with the tissue localization. The method here described is easy to performusing the same material as for common immunostaining and the same primers used for quantitative RT-PCR. Moreover, the used primers, designed with a final amplicon that spans the exon-exon junction, allow to detect the cDNA but not the gDNA sequences.
