【 摘 要 】

References(31)Cited-By(3)The distribution of sugar residues in gonocytes of the differentiating mouse testis was examined by light microscopy using 22 different kinds of lectins. Characteristic binding patterns of sWGA, VVA, and LEA in gonocytes were observed during prespermatogenesis. sWGA preferentially bound to the cytoplasm and plasma membrane of gonocytes on 16.5 days post coitus (dpc). Its reaction decreased thereafter and almost disappeared on 1.5 days post partum (dpp), but reaction reappeared on 4.5 dpp and continued until 6.5 dpp. The VVA reaction was recognized in a few gonocytes on 0.5 dpp, and remained strong until 6.5 dpp. LEA reacted strongly in the plasma membrane and cytoplasm of gonocytes from 0.5 dpp to 6.5 dpp. The present study indicates that sWGA, VVA, and LEA are useful markers for gonocytes, and the appearance or disappearance of sWGA and VVA may be related to the differentiation of gonocytes during prespermatogenesis.
