2 A1 – 3 ) tested, we found that the stretching induced by pN forces triggers a statistically highly significant increase ( p < 0.01) in the length of neurites when compared to any other group, whereas the control groups (M − MNP − , M − MNP + , and M + MNP − ) did not differ from each other ( p > 0.05).
