Stage-specific nuclear antigen is expressed in rat male germ cells during early meiotic prophase

Nuclear Skeleton Proteins: Non-Histones

“…The activity was associated with the meiotic chromosomes but absent fkom late pachytene spermatocytes or more advanced stages of spermatogenesis and also absent fkom spermatogonia, Sertoli and Leydig cells. The pattern of expression of the antigen during early meiotic stages of spermatogenesis could strengthen its possible role in meiotic division (Atanassova et al, 2000).…”
