鲤稚幼体早期发育过程中粘液细胞的发生和变化

MUCOUS CELLS IN THE EARLY DEVELOPMENTAL STAGE OF CARP

  • 摘要: 利用酸性条件下的阿新蓝染色和过碘酸-雪夫氏试剂反应相接合的方法(AB-PAS染色),对鲤早期发育过程中粘液细胞的变化作了初步研究.结果表明,鲤的粘液细胞在受精卵孵化前一天出现,密度随个体的发育而增大,成分随发育过程的进行而趋于复杂,鲤的粘液细胞可分为四种类型,Ⅰ型和Ⅱ型含单一成分,为幼稚型,Ⅲ型和Ⅳ型含复合成分,为成熟型,鲤粘液细胞在不同组织器官中的分布是不均匀的,其主要分布区是皮肤、口腔、鳃、消化道等部位.

     

    Abstract: In this paper, changes of mucous cells in the early developmental stage of carp, Cyprinus carpio, were studied by the method of histochemical techniques-a combination of Alcine Blue staining under acid conditions and PAS reaction. The mucous cells were first Observed in hatching glands at the 1st day before hatching. They appeared immediately in the mouth cavity, pharynx, gills and gut after hatching. With the development of the carp, the density, type and content of mucous cells increased and became complicated. Type I and Type IV of mucous cells containing unitary mucoitin are in immature stage and appeared earlier than Type II and Type III which are in mature stage and contain multiple mucoitins. The mucous cells mainly distributed in mucousal epidermis of such organs as skin.mouth.gill and intestine.
