Similarly, when checking the average gene expression in a certain tissue (left), it is not possible to distinguish the differences between different cells in the same tissue. Technological developments of recent years make it possible to measure the expression of genes in a tissue at the level of the single cell (right), thus characterizing with unprecedented resolution differences between cells in the same tissue
