This stromal scaffold provides the specialized microenvironment for the life-long attraction of haematopoietic precursor cells, the signals to instruct early thymocyte differentiation, the factors to guide precursor cells to different anatomical compartments, the antigenic constraints for the selection of immature T cells and the molecules necessary for the functionally mature T cells to exit to the periphery.

Though significant alterations in TEC differentiation and maintenance have been linked to debilitating states of immunodeficiency and autoimmunity, neither the molecular mechanisms responsible for regular thymus organogenesis and physiological senescence nor the pathomechanisms operational in congenital and acquired forms of thymus hypoplasia/aplasia have been completely elucidated.

Interestingly, the master regulatory triggers of sex determination are not conserved throughout the animal kingdom, and sex differentiation can be rather plastic (Cutting et al. This is particularly exemplified by teleost fishes, in which all sorts of natural hermaphroditism occur and sex changes can be induced through a variety of external factors (Godwin 2010, and references therein).

Contrary to the observed variation in the initial triggers of sex determination, the downstream genetic factors of sexual development are thought to be conserved between species because they are part of complex genetic networks with often pleiotropic effects.

Thymic epithelial cells (TECs) constitute the major component of the stroma compartment and can be subdivided according to their functional, morphological and specific antigenic features into different subpopulations including the cortical (c) and medullary (m) TEC.

The different TECs together with other stroma cells of haematopoietic (dendritic cells, macrophages, B cells) and non-haematopoietic origin (fibroblasts, endothelial cells and others) form a three dimensional meshwork.
