title: Cytoarchitecture of the thymus gland of the adult frog (Rana temporaria).
abstract: Like in other jawed vertebrates, the frog thymus consists of lymphoid cells within epithelial framework and characteristic myoid cells. Mammalian type Hassall's corpuscles are absent, but degenerative cells form so-called unicellular Hassall's bodies. Conspicuous secretory cells, secretory and degeneration cysts as well as phagocytic cells, granulocytes and plasma cells can be observed in the frog thymus. Interdigitating-like cells and some characteristic features of thymic vasculature (i.e. the existence of blood-thymus endothelial are preliminary described in the frog thymus.
