In this study, we applied dynamic nuclear polarization (DNP)
technique to investigate C1 labeled 13C pyruvate to
lactate conversion across maturation in mice in vivo.
Normal mice were scanned starting on postnatal day 18
and repeated every 10 days. Experiments were conducted
on a 14.1T NMR spectrometer with real-time metabolic
imaging simultaneously with injection of hyperpolarized
pyruvate. We found that lactate level was significantly
higher at younger ages, and stabilized around P30. The
level of lactate was also independent to the
polarization or pyruvate level.
