An embryonic cell’s fate sealed by speed of a signal

5 agosto 2014

When embryonic cells get the signal to specialize, the call can come quickly. Or it can arrive slowly. Now, new research suggests the speed at which a cell in an embryo receives that signal has an unexpected influence on that cell’s fate. «This finding is another instance of a productive collaboration between biologists and physicists. Neither group, biologists or physicists, could have realized this result working alone,» one researcher said.
