Single-Cell Multi-Omics: The Cellular Resolution Revolution
Introduction: The Cellular Resolution Frontier Biology has always been a story of scale. For decades, we studied organisms, then tissues, then cell populations — averaging signals across thousands or millions of cells. But tissues are not homogeneous. A tumor contains cancer cells, immune cells, fibroblasts, and endothelial cells, each with distinct molecular profiles. The brain contains hundreds of neuronal subtypes, each with unique functions. Even “identical” cells in culture exhibit stochastic variation in gene expression that can determine cell fate. ...
