Thymus epithelial cells (TECs) express antigens from peripheral tissues to select against autoreactive T cells and thus prevent autoimmunity. Michelsen et al. now show that molecularly defined clusters of thymic epithelial cells express and depend on skin-, lung-, liver- or intestinal-cell transcription factors that are co-opted by the thymus to drive ectopic gene expression.
