    Abstract

    Advances in genomics have redefined our understanding of thymic epithelial heterogeneity and architecture, yet signals driving thymic epithelial differentiation remain incompletely understood. Here, we elucidated pathways instructing human thymic epithelial cell development in the context of other anterior foregut-derived organs. Activation of interferon response gene regulatory networks distinguished epithelial cells of the thymus from those of other anterior foregut-derived organs. Thymic cortex and medulla epithelia displayed distinctive interferon-responsive signatures defined by lineage-specific chromatin accessibility. We explored the effects of type I and II interferons on thymic epithelial progenitor differentiation from induced pluripotent stem cells. Type II interferon was essential for expressing proteasome and antigen-presenting molecules, whereas type I or II interferons were essential for inducing different cytokines in thymic epithelial progenitor cells. Our findings suggest that interferons are critical to cortical and medullary thymic epithelial cell differentiation.
