| Outline of Final Research Achievements |
We exposed axons in cultured neuronal cells to the impulsive strain and the effect of the impulsive strain on axonal injury was evaluated at the cell level. Neural stem cells (NSCs) were used as cultured neuronal cells. NSCs can be proliferate and differentiate into neurons and glia. When cultured in medium, NSCs extend the axons towards any direction. The direction of axons growth is controlled by using micro grooves which matched with the size of the cell. Culture surface is used by micro grooves on polydimethylsiloxane (PDMS). It is transcribed from micro groove were generated by using photolithography on resist material (SU8) and the Si substrate. The axons were damaged by the rather small strain with 0.09, strain rate with0.12/s.
