웹2006년 9월 1일 · The backdrop for Balbiani body formation is the germline cyst or nest, a collection of premeiotic germ cells interconnected by intercellular bridges. In Drosophila, cysts consisting of 16 germ cells interconnected by ring canals large enough to pass organelles are established by four synchronous rounds of division with incomplete cytokinesis. 웹2024년 2월 14일 · In fetal females, oogonia proliferate immediately after sex determination. The progress of mitosis in oogonia proceeds so rapidly that the incompletely divided cytoplasm of the sister cells forms cysts. The oogonia will then initiate meiosis and arrest at the diplotene stage of meiosis I, becoming oocytes. Within each germline cyst, oocytes with Balbiani …
웹In the meiotic germ cells, the “Balbiani body,” which was composed of a concentration of cell organelles shifted to one pole of the cell, was always seen. The apperance of a meiotic nucleus and Balbiani body was characteristic of germ cells located in the left ovarian cortex, whereas those were never seen in the left medulla and in the right ovary.
