Interaction between differentiating neurons and the extracellular environment guides the establishment of cell polarity during nervous system development. Developing neurons read the physical properties of the local substrate in a contact-dependent manner and retrieve essential guidance cues. In previous works we demonstrated that PC12 cell interaction with(More)
During development and regeneration of the mammalian nervous system, directional signals guide differentiating neurons toward their targets. Soluble neurotrophic molecules encode for preferential direction over long distances while the local topography is read by cells in a process requiring the establishment of focal adhesions. The mutual interaction(More)
A single-biomolecule optical toggle-switch is demonstrated based on a mutated green fluorescent protein (GFP). We have exploited molecular biology techniques to tailor GFP molecular structure and photophysical properties and give it optically-controlled bistability between two distinct states. We present optical control of the fluorescence dynamics with two(More)
Cells are exposed to specific directional physical signals determined by the micro/nano-environment that in vivo coexist with some degree of topographical noise. Particularly in the nervous system, cell contact sensing of the extracellular environment plays a primary role in defining neurite initiation and final brain wiring. Here we study neuronal cell(More)
