Micrograph: TPX2 beading on microtubules

Caption

Researchers in the laboratories of Princeton University scientists Joshua Shaevitz, Howard Stone, and Sabine Petry have discovered that surface tension drives the liquid-like protein TPX2 to form globules that nucleate the formation of branching microtubules during cell division. The paper detailing these discoveries appeared in the Jan 28 issue of the journal Nature Physics. Here, TPX2 (green) beads on microtubules (red) in micrographs, with a one micron scalebar.
