The nurse chamber inMiastor is a syncytium containing a variable number of nuclei. Many workers have claimed that all the nurse nuclei were derived from somatic cells. However, since one of these nuclei is larger than the remaining nuclei, other workers have thought that this nucleus was germinal in origin. Our ultrastructural studies of the nurse chamber-oocyte complex demonstrate the presence of an intercellular bridge between the nurse chamber and the oocyte. Furthermore, the large nurse nucleus contains lamellae characteristic only of the germ line. Both findings indicate that one of the nurse nuclei is the sister to the oocyte.
米阿斯托（Miastor）中的滋养室是一个含有数量可变细胞核的多核体。许多研究人员声称，所有的滋养细胞核都来源于体细胞。然而，由于其中一个细胞核比其他细胞核大，其他研究人员认为这个细胞核起源于生殖细胞。我们对滋养室-卵母细胞复合体的超微结构研究表明，在滋养室和卵母细胞之间存在细胞间桥。此外，大的滋养细胞核含有仅在生殖系中特有的片层。这两个发现都表明，其中一个滋养细胞核是卵母细胞的姐妹细胞。
