abstract = {Neuronal mechanobiology plays a vital function in brain
development and homeostasis with an essential role in
neuronal maturation, pathfinding, and differentiation but is
also crucial for understanding brain pathology. In this
study, we constructed an in vitro system to assess neuronal
responses to cyclic strain as a mechanical signal. The
selected strain amplitudes mimicked physiological as well as
pathological conditions. By subjecting embryonic neuronal
cells to cyclic uniaxial strain we could steer the direction
of neuronal outgrowth perpendicular to strain direction for
all applied amplitudes. A long-term analysis proved
maintained growth direction. Moreover, stretched neurons
showed an enhanced length, growth, and formation of nascent
side branches with most elevated growth rates subsequent to
physiological straining. Application of cyclic strain to
already formed neurites identified retraction bulbs with
destabilized microtubule structures as spontaneous
responses. Importantly, neurons were able to adapt to the
mechanical signals without induction of cell death and
showed a triggered growth behavior when compared to
unstretched neurons. The data suggest that cyclic strain
plays a critical role in neuronal development.},
