Summary

Automatic Translation

Le laser femtoseconde étroitement focalisé peut fournir la stimulation précise aux cellules en étant couplé dans une microscopie confocale permettant l'observation et la photostimulation en temps réel. La photostimulation peut activer des événements moléculaires cellulaires, y compris la voie de signalisation ERK et les éclairs mitochondriaux des espèces réactives d'oxygène.
