While the demand for metabolic imaging has increased in recent years,
simultaneous in vivo measurement of multiple metabolic endpoints remains
challenging. Here we report on a novel technique that provides in vivo
high-resolution simultaneous imaging of glucose uptake and mitochondrial
metabolism within a dynamic tissue microenvironment. Two indicators were
leveraged; 2-[N-(7-nitrobenz-2-oxa-1, 3-diazol-4-yl) amino]-2-deoxy-D-glucose
(2-NBDG) reports on glucose uptake and Tetramethylrhodamine ethyl ester (TMRE)
reports on mitochondrial membrane potential. Although we demonstrated that there
was neither optical nor chemical crosstalk between 2-NBDG and TMRE, TMRE uptake
was significantly inhibited by simultaneous injection with 2-NBDG in vivo. A
staggered delivery scheme of the two agents (TMRE injection was followed by
2-NBDG injection after a 10-minute delay) permitted near-simultaneous in vivo
microscopy of 2-NBDG and TMRE at the same tissue site by mitigating the
interference of 2-NBDG with normal glucose usage. The staggered delivery strategy
was evaluated under both normoxic and hypoxic conditions in normal tissues as
well as in a murine breast cancer model. The results were consistent with those
expected for independent imaging of 2-NBDG and TMRE. This optical imaging
technique allows for monitoring of key metabolic endpoints with the unique
benefit of repeated, non-destructive imaging within an intact microenvironment.
