Research Abstract

Recently, bioactuators that exhibit self-organization have been attracting a lot of attention, because biological devices are expected to have significant abilities such as self-reproduction, self-repair, self-assembly. Based on this consideration, we have developed a myofilament-actuator, where we have utilized effects of a mechanical stimulation to construct the mechanical structure of such a bio-actuator. More specifically, we found that induction of differentiation into myofilament-like cells from a cultured myoblasts C2C12 is promoted under the mechanical stimulation.
