For effective tissue regeneration, we have developed a three dimensional cell culture system capable of mechanical cell stimulation. The degree of ERK phosphorylation and the cell proliferation ratio of three dimensionally cultured mouse skeletal muscle cells were improved by stretch stimulations in a system composed of newly developed self-assembling peptide gel and stretch chamber. These results demonstrated that the three dimensional stretch cell culture system was able to transmit mechanical stimulation to the cell and control its behaviors such as cell proliferation.
