A cytokinetic ring-driven cell rotation achieves Hertwig's rule in early development

TC Middelkoop, J Neipel, CE Cornell… - Proceedings of the …, 2024 - National Acad Sciences
Hertwig's rule states that cells divide along their longest axis, usually driven by forces acting
on the mitotic spindle. Here, we show that in contrast to this rule, microtubule-based pulling …
