Researchers showed that the genes turned on by the switch remained active for several hours in several mammalian cell lines even after a short light pulse. (sciencedaily.com)
The effect was observed in multiple mammalian cell lines, including both normal and tumorigenic models. (sciencedaily.com)
These modifications have enabled researchers to image living cells, such as mammalian cell lines or mature hippocampal neurons, without any sign of cellular damage. (sciencedaily.com)
