This Week in Science

In Science this week, a group led by Karolinska Institute scientists report on a strategy for visualizing and analyzing gene expression in tissue sections using spatial transcriptomics. By positioning histological sections on arrayed reverse transcription primers with unique positional barcodes, the researchers generated high-quality RNA-sequencing data with maintained two-dimensional positional information in mouse brain tissue and human breast cancer tissue.
