scRNA-seq

Single-cell RNA sequencing (scRNA-seq) is a technology that examines the gene activity of individual cells. By isolating each cell and analyzing its RNA—the molecules that carry instructions from DNA—it reveals which genes are active and to what extent. This detailed view helps scientists understand cell types, how they function, and how they differ within a complex tissue. It’s a powerful tool for studying development, disease, and the diversity of cells in the body, providing insights that bulk analysis of many cells cannot offer.
