title: Presence of tonofilaments and thymic serum factor (FTS) in thymic epithelial cells of a fresh water fish (carp: Cyprinus carpio) and a sea water fish (bass: Dicentrarchus labrax).
abstract: Using indirect immunofluorescence we demonstrated the presence of FTS in two fishes; the size of epithelial cells of the carp is smaller than of the bass.
