Beckerle, Mary C. | Mathematical modeling of the dynamic mechanical behavior of neighboring sarcomeres in actin stress fibers | Actin stress fibers (SFs) in live cells consist of series of dynamic individual sarcomeric units. Within a group of consecutive SF sarcomeres, individual sarcomeres can spontaneously shorten or lengthen without changing the overall length of this group, but the underlying mechanism is unclear. We us... | 2014-01-01 | |
