thymic epithelial cell

The epithelial cells that form the internal scaffolding of the thymus. These cells vary in shape and size but generally align in sheets and cords, partitioning the thymus into islands of close-packed lymphocytes in the organ's cortex. Thymic epithelial cells are not simply structural and they interact actively with adjacent lymphocytes.

Within the thymus, thymic epithelial cells (TECs) provide key inductive microenvironments for the development and selection of T cells that arise from hematopoietic progenitors.
Type B1 thymoma is a tumor of thymic epithelial cells closely resembling normal thymus.
Extrathymic influences regulating the secretory function of thymic epithelial cells and the stepwise evolution of T cells can be ascribed to circulating interleukins, mainly IL1 and IL2, derived from activation and secretion of leukocytes in the periphery.
