Monitoring oxygen uptake in 3D tissue engineering scaffolds by phosphorescence quenching microscopy

Biotechnology Progress, 2010
AbstractMeasuring oxygen concentration in three‐dimensional cultures, without interfering with cellular activities, is a fundamental request of tissue engineering research. Among the other techniques, it has been demonstrated that phosphorescence quenching microscopy (PQM) represents a valid tool for the detection of oxygen concentration in 3D ...

Abstract LB557: Multiphoton phosphorescence quenching microscopy reveals kinetics of tumor oxygenation during anti-angiogenesis and angiotensin signaling inhibition

Cancer Research, 2022
Abstract Purpose: The abnormal function of tumor blood vessels causes hypoxia fueling disease progression and conferring treatment resistance. The local level of oxygen experienced by a cell will determine its response, making it critical to understand tissue oxygen levels with a spatial resolution on the order of the size of a cell ...

Interstitial Po₂ Determination by Phosphorescence Quenching Microscopy

Microcirculation, 2002
ABSTRACTObjective: This study introduces the technique of microinjection of phosphor probe into skeletal muscle tissue to determine oxygen tension (Po2) in the interstitium by phosphorescence quenching microscopy.Method: The spinotrapezius muscle of Wistar‐Kyoto rats weighing 240–280 g was surgically isolated and underwent the microinjection procedure.

Po₂measurements in the microcirculation using phosphorescence quenching microscopy at high magnification

American Journal of Physiology-Heart and Circulatory Physiology, 2008
In phosphorescence quenching microscopy (PQM), the multiple excitation of a reference volume produces the integration of oxygen consumption artifacts caused by individual flashes. We analyzed the performance of two types of PQM instruments to explain reported data on Po2in the microcirculation.
