Tugging at cells with molecules and light

A new method for cellular stimulation

20-Dec-2016

Everyone is made up of approximately 100 trillion cells – if they were laid end to end, they would circle the globe 60 times. Most of these cells arise from mitosis and differentiation of a single egg cell. To orientate themselves, they constantly explore their environment and communicate with ...
