New Biopsy Technology from UC Irvine Profiles Multiple Tissue Biomarkers Simultaneously

By News Release

A team at the University of California Irvine has developed new biopsy technology that can profile multiple tumor microenvironment biomarkers simultaneously, revealing cellular spatial organization and interactions that may further personalize disease diagnosis and treatment.

The fluorescence imaging-based technology, Multi Omic Single-scan Assay with Integrated Combinatorial Analysis, can spatially profile a large number of mRNA and protein markers in cells and tissues, including clinical tumor tissues. A study published in Nature Communications shows that MOSAICA enables direct, highly multiplexed biomarker profiling in a 3D spatial context using a single round of staining and imaging instead of the repeated processing steps typically needed in conventional methods.

Clinicians and scientists will now have a holistic view of the different immune and cancer cell types in tumor tissues, providing greater insight for determining patient prognosis and treatment.

“Spatial biology is a new science frontier and mapping out each cell and its function in the body at both the molecular and tissue level is fundamental to understanding disease and developing precision diagnostics and therapeutics,” said Weian Zhao, PhD, UCI professor of pharmaceutical sciences and study co-corresponding author. “Many cancer immunotherapeutics, including immune checkpoint inhibitors, don’t work and scientists realized that was because of the spatial organization of all the tumor tissue cell types, which dictates drug efficacy. The MOSAICA can characterize the spatial cellular compositions and interactions in the tumor immune microenvironment in biopsies to inform personalized diagnosis and treatment.”

A startup company called Arvetas Biosciences, Inc. was co-founded by Dr. Zhao and Alan K. Hauser, PhD, to further develop and commercialize the technology for widespread use, ranging from oncology to neurological disorders. The company is being incubated at University Lab Partners and is supported by UCI Beall Applied Innovation. Arvetas recently received a $400,000 Small Business Innovation Research grant from the National Cancer Institute to further refine and validate the technology in translational oncology.
