Experiments in Xenopus embryo extracts reveal that changes in cellular biochemistry cause mitotic spindles to decrease in size over the course of early development.
Figure 1. Embryos undergo multiple rounds of rapid division during the early stages of development of many animals. As the cells become progressively smaller, the spindles inside them also decrease in size. Reproduced from Wilson (1897).
