Mursla Bio publishes peer-reviewed study in the Journal of Extracellular Vesicles, validating its tissue-specific extracellular vesicle (TS-EV) platform for liquid biopsy.
This study validates our platform for a new class of liquid biopsy: the multiomic disease biology of living cells in a chosen tissue, read from blood, starting with the liver.
Our findings demonstrate the powerful advantages of isolating hepatocyte-derived EVs (h-EVs) over conventional bulk EV approaches:
🔬 A different proteome, not merely a deeper one: bulk EV isolates were dominated by abundant blood-secreted proteins, while h-EVs recovered the intracellular and membrane proteome of hepatocytes, and still identified 57% more proteins with higher reproducibility.
🔬 Disease signatures absent from bulk EVs: 86 liver disease-associated proteins in h-EVs versus 4 in bulk; the proteins unique to HCC h-EVs formed a coherent interaction network, while those unique to bulk EVs formed none.
🔬 Reduced miRNA diversity, richer disease association: h-EVs retained fewer microRNAs, yet only these mapped to HCC-relevant signalling pathways; bulk EV miRNAs reflected generalised inflammation.
These findings strengthen the scientific foundation of EvoLiver™, our FDA Breakthrough Device-designated blood test for liver cancer surveillance, and our precision medicine partnerships with pharmaceutical companies.
And the potential extends far beyond the liver. With further tissue-specific panels in development, our platform could unlock new opportunities in disease surveillance, molecular residual disease detection and precision medicine, from patient stratification to companion diagnostics.
