摘　　要：本研究通过形态解剖、免疫组织化学等技术,对中华蜜蜂Apis cerana cerana工蜂蕈形体胚后发育中神经胶质的形成过程进行了比较研究。结果表明:蕈形体中神经胶质增殖的高峰期集中在幼虫发育末期到蛹发育早期;在工蜂蕈形体的蕈体冠、蕈体柄以及小叶的发育过程中,神经胶质细胞往往先于神经纤维网出现在特定的区域,引导神经纤维网的形成。它们一方面规定了神经纤维网的边界和区域,为神经纤维网提供内部的分隔;另一方面也为神经纤维的移动提供特定的"路标"和靶向。与神经纤维网相关联的神经胶质的数量的持续增加,除了神经胶质的分裂增殖外,还有一部分来自于外部细胞体层的神经胶质的迁入。The characteristics of glial patterns during postembryonic in mushroom body of the honeybee Apis cerana cerana were studied based on the method of anatomy and immunohistochemistry(5-bromo-2-deoxyuridine,BrdU immunostaining).The results indicated that glial cells are involved in several functions during the development of the nervous system in the honeybee.In the early larva,a continuous layer of glial cell bodies defines the boundaries of all growing neuropiles.Initially,the neuropiles develop in the absenc...
