Formation of the first cleavage furrow in the telolecithal egg of Loligo was studied with the electron microscope. Before the actual furrow forms, a dense filamentous band develops below the plasma membrane from membrane-bounded dense bodies which appear to be Golgi-derived. The egg surface is thrown into a number of longitudinal folds which parallel the furrow and eventually become incorporated into it. These longitudinal folds contain a network of tubules and vesicles. Frequently, multivesiculate bodies are associated with the furrow and possibly give rise to the network of tubules and vesicles. Apparently part of the membrane between the two new blastomeres is derived from the surface of the longitudinal folds. The theory of furrow formation by contraction is discussed in light of the filamentous band.
利用电子显微镜研究了枪乌贼端黄卵中第一次卵裂沟的形成。在实际的卵裂沟形成之前,从似乎源自高尔基体的膜结合致密体在质膜下方形成一条致密的丝状带。卵表面形成许多与卵裂沟平行的纵向褶皱,最终并入卵裂沟中。这些纵向褶皱包含一个小管和小泡网络。多泡体常常与卵裂沟相关联,并可能产生小管和小泡网络。显然,两个新的卵裂球之间的部分膜源自纵向褶皱的表面。根据丝状带讨论了通过收缩形成卵裂沟的理论。
