摘　　要：对家蚕晚期胚胎组织进行原代培养,记录了培养过程中出现的多种分化和转分化现象。发现已分化的晚期胚胎组织、细胞尚可继续分化和转分化形成各种不同类型的组织与细胞,而且这些细胞多有一定的增殖能力,暗示了家蚕晚期胚胎组织可能有多种内部器官组织的多能干细胞存在。In the process of primarily culturing advanced embryo tissues in Bombyx mori,which lasted over one year,we recorded the various differentiations and transdifferentiations,discovered that the differentiated advanced embryo tissues and cells could differentiate and transdifferentiate as diverse tissues and cells,furthermore,we also found out that majority of these cells were able to proliferateat some extents,indicating Bombyx mori advanced embryo tissues probably have multifunctional stem cells which subsequently develop as internal organs.
