The centrosome is a structure in cells which is built every time the cell prepares to divide. In this video abstract, Jeff Woodruff explains how to build a centrosome in a test tube from purified proteins. He found that the centrosome acts like a sponge, which selectively soaks up the proteins needed to build microtubules.
Jeff Woodruff is a postdoc in the lab of Tony Hyman (hymanlab.org) at the Max Planck Institute of Molecular Cell Biology and Genetics in Dresden, Germany
