These microscopic images show gene expression in muscle stem and progenitor cells as they mature from early development to adulthood (left to right). As part of this process, the cells switch from actively expressing one key gene (green) to another (violet); this is accompanied by the growth of muscle fibers (red).

Normal airway tissue, left, and lung cancer tissue, right, with an overabundance of basal stem cells (green). The activated form of beta-catenin (red) in the lung cancer can be targeted by the Wnt Inhibitor Compound 1.
Image showing brain cells with lower levels of Foxp1 function (at left) and higher levels (right). Apical radial glia are stained in green and secondary progenitors and neurons stained in red.
