How cell nuclei squeeze into tight spaces

As cells move throughout our bodies, they often have to squeeze through tight nooks and crannies in their environment, reliably springing back to their original shape. The structures involved in this process are still a mystery, but in a study published August 22 in Developmental Cell, a research team reports one protein responsible for giving a cell's nucleus its durable, deformable nature. These results, the authors say, may explain the invasiveness of certain cancer cells.
