Multicellularity is one of the most profound phenomena in biology, and relies on the ability of a single cell to reorganize itself into a complex organism. It underpins the diversity in the animal ...

Microtubule asters in cytoplasmic extract of the African clawed frog Xenopus laevis. The spatio-temporal growth of the aster is coordinated by cell cycle waves that drive the polymerization (brighter ...

Using CRISPR-based engineering methods to prompt stem cells to organize into embryo-like structures, scientists were able to create 'programmable' cellular models of embryos without ever experimenting ...

For a developing frog embryo, gravity is more than the force that keeps it on the ground. It can provide a reference for how the egg is oriented as development begins, helping establish the direction ...
