title: Cellular sources of thymic hormone (thymosin) in human thymus.
abstract: Antiserum against partially purified calf thymosin (5) was used for the localisation of this complex material in human thymus for comparison with calf thymi. Antithymosine IgG produced with human thymosin 5 by comparative immunoelectrophoresis one line identical with one of the lines of calf thymosin 5. Immunofluorescent evidence suggests the presence of the material in question, which also contains a biologically active principle, mainly in the epithelial cells of the thymus cortex. The contents of the traced material, however, fluctuates substantially between individual thymic lobules.
