In vivo lineage tracing reveals Axin2-expressing, long-lived cortical thymic epithelial progenitors in the postnatal thymus.
In the thymus, cortical and medullary thymic epithelial cells (TECs) are instrumental for generating a repertoire of functional T cells.Hence, there has been much interest in the ontogeny of TECs.While medullary TEC (mTEC) and bipotent progenitors have been identified, the existence of a cortical TEC (cTEC) Commercial Product (Sanitization) progeni
