Interkinetic Nuclear Migration: Reciprocal Activities of Dynein and Kinesin

Cell Adhesion & Migration. 2011. Vol. 5. No. 4. P. 277-279.

A hallmark of neurogenesis in vertebrates is the apical-basal fluctuation of radial glia nuclei. Such a phenomenon, called INM, has been known for decades and is closely associated with mitosis but still puzzles scientists. An impressive step in the molecular understanding of INM has recently been achieved by Tsai and coworkers. Using RNA interference associated with time-lapse imaging, these authors demonstrated a dual motor system that can push/pull the nuclei accordingly with the cell cycle stages.
