Figure 1: Expression profile of PLZF in cross section and whole mount IHC. PLZF was immune-stained strongly in undifferentiated A spermatogonia throughout the seminiferous cycle. (a) A4 was PLZFLOW in stage I, (b) In was PLZFNEG in stage III, (c) B was PLZFNEG in stage V, (d) A1 was PLZFHIGH in stage VII, (e) A2 was PLZFLOW in stage X, (f) A3 was PLZFLOW in stage XII in cross section and whole mount IHC. Aun: black arrows; A1: red arrows; A2: green arrows; A3: yellow arrows; A4: blue arrows; In: grey arrows; B: cyan arrows; preleptotene: black asterisks; leptotene: red asterisks; zygotene: green asterisks; early pachytene: yellow asterisks; mid-pachytene: blue asterisks; late pachytene: grey asterisks; diplotene: pink asterisks; meiotic division: cyan asterisks; Sertoli cells: black arrowheads; round spermatid: black triangles; elongating spermatid: red triangles. Scale bar=25 μm. PLZF: promyelocytic leukemia zinc finger; IHC: immunohistochemistry.
