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 was a postdoc in the lab of Tony Hyman at the Max Planck Institute of Molecular Cell Biology and Genetics in Dresden, Germany.
Update: Jeff is now an Assistant Professor at UT Southwestern Medical Center in Dallas, Texas!
