Latest Patents

Peter Donovan holds a patent for a groundbreaking method titled "Phasor method to fluorescence lifetime microscopy to discriminate metabolic state of cells in living tissue." This innovative approach provides a label-free imaging method to monitor stem cell metabolism, allowing for the discrimination of different states of stem cells as they differentiate in living tissues. The method utilizes intrinsic fluorescence biomarkers and the phasor approach to Fluorescence Lifetime Imaging Microscopy (FLIM). It identifies and maps intrinsic fluorophores such as collagen, retinol, retinoic acid, flavins, nicotinamide adenine dinucleotide (NADH), and porphyrin. The phasor values of germ cells in the germ line are measured, and their metabolic fingerprints cluster according to their differentiation state. This reflects changes in FAD concentration and NADH binding during the differentiation pathway. The phasor approach provides a sensitive method to identify different metabolic states of cells during differentiation, enabling the detection of small changes in the redox state of cells and potentially predicting cell fate.
