Intercellular bridges have been detected in ovarian follicle cells of Drosophila melanogaster. These bridges occur widely between follicle cells of previtellogenic chambers, while, in vitellogenic chambers, they become restricted to the columnar follicle cells. Usually, only one bridge is detectable between adjacent follicle cells, but a single cell may form two cytoplasmic continuities. The fine structure of the intercellular bridges is similar to that previously described in the development of Drosophila. The bridge wall consists of two layers of which the more external is more electron dense and thinner than the inner one. The role played by the intercellular bridges in the determination of asynchronous differentiation of the linked follicle cells is discussed in relation ot the known behaviour of these cells in the secretion of the egg covering precursors.
在黑腹果蝇的卵巢卵泡细胞中已检测到细胞间桥。这些桥广泛存在于卵黄生成前小室的卵泡细胞之间，而在卵黄生成小室中，它们局限于柱状卵泡细胞。通常，相邻卵泡细胞之间只能检测到一个桥，但单个细胞可能形成两个细胞质连续性。细胞间桥的精细结构与先前在果蝇发育中描述的相似。桥壁由两层组成，其中外层比内层电子密度更高且更薄。结合这些细胞在卵壳前体分泌中的已知行为，讨论了细胞间桥在相关联的卵泡细胞异步分化确定中所起的作用。
