Shinya Inoue (2011) CIL:11973, Thyone briareus, sperm. CIL. Dataset

The movie shows, in real time, the explosive acrosomal reaction of Thyone (sea cucumber) sperm. The field shows several sperm heads (bright contrast) with tails of some in the plane of focus. From the head at lower left, a thin thread, resulting from the rapid polymerization of actin, is extruded. The acrosomal process is thought to contribute to fertilization by penetrating the jelly coat of the egg.

本视频实时展现了海参（Thyone）精子中的爆炸性顶体反应。画面中清晰展示了多个精子头部（对比鲜明）及其部分尾部位于焦点平面上。从左下方的头部出发，由肌动蛋白快速聚合形成的细丝被排出。据信，顶体过程通过穿透卵子的胶状层，对受精过程起到促进作用。
