The hand that rocks the spindle

Asymmetric cell division is a fundamental process by which cells give rise to progenies with different fates. Although this mechanism is well studied in the worm and fly, mammalian asymmetric cell division is poorly understood. The finding that Gβγ and AGS3 can control mitotic spindle orientation and progenitor cell fates during mouse cortical development suggests evolutionarily conserved roles in asymmetric cell division.
