Summary

Automatic Translation

Strak gerichte femtosecondelaser laser kan precieze stimulatie naar cellen leveren door te worden gekoppeld aan een confocale microscopie die de real-time observatie en foto stimulatie mogelijk maakt. De foto stimulatie kan celmoleculaire gebeurtenissen activeren, waaronder ERK-signalerings traject en mitochondriale flitsen van reactieve zuurstof soorten.
