Realtime video of cellular response to pulsed near infrared “Light”

Cell signalling governs basic cellular activities and coordinates cell actions. Cells respond to their local microenvironment and these signals may prompt tissue repair or immune response as well as normal tissue homeostasis. Guenter Albrecht-Buehler has conducted a series of experiments on cells with near-infrared light (NIR) and reports on how cells might be communicating with pulsed NIR. He also demonstrates with video how cell motility responds to a pulsed light stimulus.
