Fig. 3 Characterization of adult zebrafish thymus tissue. (A) Haematoxylin–eosin staining of a zebrafish thymus 6 weeks after fertilization. Note the darkly stained thymus (th) adjacent to the gill chamber (gi). la, larynx; hb, hindbrain. (B) Binding pattern of ConA lectin in zebrafish thymus; inset, adult mouse thymus. The presumptive cortical (co) and medullary (me) regions are indicated. (C) RNA in situ hybridization with radio-labelled rag-1 probe; silver grains are displayed in false colour (green). (D) Analysis of whnb in thymus section at the cortico-medullary junction. Note the equal distribution of silver grains (black dots). (E) Analysis of whna in thymus section at the cortico-medullary junction. Note that expression is confined to a few cells.
