Researchers at Harvard Medical School have published a new study in Cancer Discovery on how ovarian cancer cells act in the body, reports New Scientist. As shown in the time-lapse video below, the researchers attached the cancer cells to peritoneal cells and filmed the interaction in a Petri dish for 14 hours, in order to see how ovarian cancer cells break through the membrane to get to other organs. It appears that the tumor cells are able to break through the healthy membrane cells beneath them by using proteins involved in cell movement to "force them out of the way," New Scientist says. The researchers, who think the discovery could aid in the search for therapies, say the cancer cells "act like bullies."
