In a recent study, Mayo Clinic researchers developed the first cellular DNA barcoding with a machine-learning approach to reveal previously unknown metastatic behavior of tumor cells. Researchers barcoded the DNA of millions of human ovarian cancer cells and transplanted them in mice, where rare tumor initiating cells and their progenies could be tracked within the primary tumor as well as in every other organ they were spreading into. The entire community of cells generated by a single barcoded cell had identical barcodes. This enabled the tracking of a large number of benign and metastatic clones by sequencing DNA barcodes in tumors and various organs, including blood and ascites. Using the cellular DNA barcoding approach and a newly developed data analysis system, researchers could track clonal growth dynamics in various metastatic sites and trace it back to its ancestral tumor-initiating cell. They used artificial intelligence to tackle the complex data to identify if the clonal metastatic spread is happening peritoneally or through blood routes.

In this episode, John and Dr. Pritt discuss how Mayo Clinic swiftly operationalized monkeypox testing and the challenges involved with supporting the new assay, including staffing.

In July 2022, Mayo Clinic Laboratories announced fifteen new tests along with numerous reference value changes, obsolete tests, and algorithm changes.

Todd Walker is a laboratory supervisor for Mayo Clinic Laboratories, Specimen Operations, where he helps lead the department that serves as the gateway between collecting and delivering specimens and getting them processed. Todd credits his diverse, agile team and the impressive global logistics infrastructure that allows them to support the processing of 40,000 specimens in a day.

Rajiv Pruthi, M.B.B.S., explains how Mayo Clinic Laboratories’ serotonin release assay achieves high sensitivity and specificity while avoiding the use of radioactive materials. Serotonin release testing is an important tool in the diagnosis of heparin induced thrombocytopenia, or HIT, which can have devastating consequences for patients.
