CIL:39229, Psophus stridulus, spermatocyte. In Cell Image Library

Time lapse movie of meiosis II in spermatocytes of the Locust Psophus stridulus showing telophase and the early spermatid stage. This is a historic movie made in the early 40s by Kurt Michel of the Zeiss company in Jena using Zernike's newly invented phase contrast microscope. Despite its early date, the movie and the others in the group remain some of the clearest examples of chromosome behavior during meiosis.

本延时摄影影片记录了斑翅蝗（Psophus stridulus）精母细胞的减数分裂II（meiosis II）过程，涵盖分裂末期与早期精细胞阶段。该经典影像由耶拿Zeiss公司的库尔特·米歇尔（Kurt Michel）于20世纪40年代初，借助泽尼克（Zernike）新近发明的相差显微镜（phase contrast microscope）拍摄完成。尽管拍摄年代较早，该影片与同批次其他影像仍为减数分裂过程中染色体行为观测的最为清晰的典型案例之一。
