Using a combination of diverse experimental techniques and modeling, Sung Hoon Lee, a postdoctoral associate in the Levchenko lab, worked with researchers at Yale and UMN to unravel the molecular network inside the cells and the carefully separated ‘beats’ controlling cell movement. “We were surprised to find that cancer cells or cells that arose from healthy tissues moved in periodic steps”, said Andre Levchenko, Director of Yale ’s Systems Biology Institute, and lead author of the study. Published in Cell Systems, researchers at Yale and the University of Minnesota (UMN) have discovered that the migration of cells though confining spaces is controlled by a kind of molecular clock. Until now, these intricate cellular movements have been little understood. Tick tock is a powerful design and manufacturing model, but the next era of computing brings with it new, complex product development demands. A wealthy man becomes suspicious of his younger wife and hires a private detective in time to thwart her plans to have him killed. We have a fantastic selection of clocks for all rooms in the house, and also a great range of outdoor products. In so called ‘invasive migration ’, cells find themselves in dense molecular matrices that lend the elastic properties giving tissues their shapes and forms. With Megan Ward, Kristin Minter, Linden Ashby, John Ratzenberger. Tick Tock Clocks is one of the UKs largest independent clock websites. This happens for many reasons, for example in wound healing or the metastatic spread of cancer. Living cells usually stay put in their ‘assigned’ areas within an organism, but now and then they start moving to ‘invade’ the surrounding areas.
