A Swiss Army Knife for Genomic Data
April 5, 2021Caltech
A good way to find out what a cell is doing whether it is growing out of control as in cancers, or is under the control of an invading virus, or is simply going about the routine business of a healthy cell is to look at its gene expression. Though a vast majority of cells in an organism all contain the same genes, how those genes are expressed is what gives rise to different cell types the difference between a muscle cell and a neuron, for example.
In the last decade, technologies to measure gene expression in individual cells have revolutionized biology. No longer do biologists need to average out gene expression over many cells within tissues; now they can detect which genes are active in each cell at any time.
