Clinical Technoshot: in situ Multiplex RNA-FISH

New Generation Sequencing technologies allowed to move the first steps towards a personalized medicine. However, they suffer an important limitation that resides in the inability to preserve single-cell resolution. The association of a genomic/transcription profile to distinct cell components in different histological locations provides an enormous amount of information. We thus decided to try to identify and quantify RNA molecules in situ starting from recently published methods.
