Summary

Traduzione automatica

Stramt fokuseret at laser kan levere præcis stimulation til celler ved at blive koblet til en Konfokal mikroskopi muliggør real-time observation og foto stimulation. Foto stimulation kan aktivere celle molekylære hændelser, herunder ERK signalering pathway og mitokondrie blinker af reaktive oxygenarter.
