The Incredible Shrinking Spindle

Publication date: 21 May 2018
Source:Developmental Cell, Volume 45, Issue 4
Author(s): Christopher Brownlee, Rebecca Heald
As cell size decreases during the reductive divisions of early development, intracellular structures must shrink to fit. In this issue of Developmental Cell, Lacroix et al. (2018) identify a conserved mechanism of spindle scaling in nematode and sea urchin embryos whereby spindle microtubule polymerization rates decrease as development proceeds.
