How growing cells move togetherOur cells are more than inert bags of proteins and genes whose complex signaling networks confound the world’s most powerful computers. They also have a physical side whose brawny feats may guide our basic good health. For the first time, researchers at Harvard School of Public Health (HSPH) have directly measured the physical forces at play when growing cells move together. The findings open up new avenues for exploring how the mechanical properties of cells sculpt new organs, shape full human beings, close a bleeding wound, form tumors, and propel metastasis. |
