    Jawless fish were recently shown to possess T- and B-like lymphocytes expressing diverse assembled antigen receptors. This study identifies and characterizes lympho-epithelial thymus-like structures at the tips of gill filaments of lamprey larvae, thus providing evidence that the similarities underlying the adaptive immune systems of both types of vertebrate appear to extend to primary lymphoid organs.

    The thymus contains thymic epithelial cells (TECs), which form a complex three-dimensional network organized into cortical and medullary compartments. It is shown here that these cells are plastic. Clonogenic TECs can acquire new properties when exposed to the skin microenvironment; under such conditions, they can permanently adopt the fate of hair follicle multipotent stem cells. Hence, microenvironmental cues can be sufficient to re-direct epithelial cell fate.
