Endofluorescence Imaging of Murine Hepatocellular Carcinoma Cell Culture by Fluorescence Lifetime Microscopy with Modulated CMOS Camera

In this work, we propose the results of pilot studies on using the modulated CMOS camera for the imaging of autofluorescence in murine hepatocellular carcinoma cells with excitation in UV light. Here, we assess the capabilities of the imaging system to detect changes in the NAD(P)H fractions produced and utilised in the glycolysis, pentose phosphate pathway and oxidative phosphorylation. Our results suggest that the camera and the system based on one possess a sufficient margin of SNR and sensitivity to detect the cellular metabolic changes associated with the metabolic pathways mentioned.
