Cells 'feel' their surroundings using finger-like structures

Cells have finger-like projections that they use to feel their surroundings. They can detect the chemical environment and they can 'feel' their physical surroundings using ultrasensitive sensors. New research from the Niels Bohr Institute shows how the finger-like structures, called filopodia can extend themselves, contract and bend in dynamic movements. The results are published in the scientific journal, Proceedings of the National Academy of Sciences, PNAS.
