Optical trap pulls apart cell division mystery

Facebook X LinkedIn Email
David L. Shenkenberg

Cell division must happen during the life of every organism, but if unregulated, it causes cancer. However, the protein mechanisms behind mitosis are not fully understood. To further explore cell division, researchers at the University of Washington in Seattle have employed optical tweezers and a piezo microscope stage. In particular, they studied whether tension directly or indirectly affects microtubules, protein strands that organize and subsequently pull apart chromosomes during mitosis through growth and shortening processes. It is believed that tension controls microtubule growth and...Read full article
