At AGBT, researchers reveal new findings from studies leveraging Illumina’s multiomics solutions
SAN DIEGO, Feb. 25, 2026 /PRNewswire/ — Illumina, Inc. (NASDAQ: ILMN) today announced new customer breakthroughs in oncology powered by Illumina’s spatial transcriptomics, 5-base sequencing, and proteomics technologies. The ability to combine more than one omic insight reveals unprecedented biological depth and knowledge, all of which is streamlined by Illumina Connected Multiomics for multimodal data analysis. The combined portfolio delivers new insights for precision diagnostics, targeted therapeutics development, and understanding of tumor microenvironments.
“Unlocking the human genome has changed the face of cancer care and opened up demand for the next wave of biological insights,” said Jacob Thaysen, chief executive officer at Illumina. “Researchers are rapidly adopting multiomics and informatics technologies that expand our understanding of biology at scale. Illumina’s streamlined multiomics workflows are enabling customers to achieve game-changing breakthroughs in oncology, pharmacogenomics, and more.”
Illumina Spatial Technology decodes complex tissues with ease
The human lymphatic system is notoriously difficult to map due to its size and variability among individuals. Spatial technology holds promise to probe biomolecular signatures that can improve the diagnosis and prognosis of cancer and even explain how it metastasizes in the body.
Dr. Ioannis Vlachos, PhD, director of the Spatial Technologies Unit within Beth Israel Deaconess Medical Center (BIDMC), leveraged Illumina Spatial Technology and visualization software to investigate human lymph nodes and lymphatic channels.
“Our research as an NIH HuBMAP Tissue Mapping Center aims to shed light on the complex function of lymphatic vessels, which are exceptionally challenging samples due to their low adhesion, surrounding adipose tissue, and small size. Illumina Spatial Technology generated high-quality data from samples ranging from very small to quite sizable, producing the first ever whole transcriptome spatial datasets for human lymphatic collector vessels,” said Vlachos. “The large capture area and serial sections helped us resolve single‑cell‑thick layers and reconstruct three‑dimensional representations of tissue organization with whole transcriptome capture at 1um resolution. Our institution and the broader research community can use these datasets to answer many possible research questions.”
In another study conducted by Illumina researchers, Illumina Spatial Technology outperformed other competing technologies for improved sensitivity, higher resolution, and higher throughput at a lower cost.
The study mapped breast cancer progression across a range of precancerous to high-grade ductal carcinomas. Whole-transcriptome profiling revealed unexpected nuances of tumor microenvironments, including identification of a novel set of cancer-associated fibroblasts. Researchers found more than 2000 unique transcripts in each cell, showing an unprecedented level of sensitivity.
“Each tumor is unique and its gene expression is never uniform,” said Cande Rogert, vice president and global head of advanced sciences at Illumina. “By interrogating a large surface area of tissue at high resolution, we were able to analyze the tumor genetics within their real context and identify new cell subtypes. The resulting multiomic insights provide additional information and have the potential to drive more precise therapeutic development.”
Illumina 5-base solution delivers epigenetic context for cancer diagnostics
A team of researchers from Broad Clinical Labs, working with hospital research partners in Boston and Europe, recently explored the application of Illumina’s 5-base solution to support clinical research for pediatric kidney cancer. This type of cancer typically requires invasive surgical procedures to diagnose, monitor, and treat that are not always feasible.
The researchers are seeking genomic alternative approaches. Existing translational research ctDNA assays can miss disease signals in very rare tumors such as Wilms and rhabdoid. Illumina’s 5-base solution enabled simultaneous genomic and methylation profiling to add additional epigenomics signals that identify cases missed by conventional approaches.
Illumina 5-base whole genomes from renal cancer patients were tested in methylation-based classifiers and were able to predict the presence of rhabdoid tumors missed by genomics-only methods. Future work will expand 5-base profiling to additional FFPE and cfDNA samples, with the goal of training advanced machine learning models. These efforts may ultimately provide clinicians with more accurate diagnostic insights and improve outcomes for patients.
“Combining these molecular signals in a single, scalable process can help us develop non-invasive diagnostics for cancers,” said Carrie Cibulskis, director of cancer genomics at Broad Clinical Labs. “We’re working toward a minimally invasive methylation-aware assay for cancer diagnosis and treatment selection.”
Integrated multiomics improves understanding of advanced ovarian cancer
Nearly 80% of ovarian cancers are diagnosed at advanced stages, where survival drops to about 30%. When caught early, survival exceeds 90%. For women presenting with an adnexal mass, accurately distinguishing between benign and malignant disease is critical to guiding appropriate referral and surgical care, yet current diagnostic tools lack sufficient accuracy to reliably support these decisions.
Bodour Salhia, PhD, a professor of cancer biology at the University of Southern California’s Keck School of Medicine applied Illumina’s 5-base solution, Illumina Protein Prep, and Illumina Spatial Technology to adnexal masses. The method enabled them to more easily differentiate between cancerous and benign tumor types using cell-free DNA and explore more sensitive ways to gain deeper biological context for ovarian cancer. Results included the first reported spatial analyses of adnexal masses and revealed localized tumor biology not previously reported.
“These findings create a multiomic framework for ovarian cancer research and lay the groundwork for an effective liquid biopsy in particularly challenging ovarian cancers with the potential to transform diagnostic practices and outcomes,” said Salhia. “Layering the omics gave us a winning combination, providing more context for earlier cancer identification.”
Illumina’s 5-base solution allowed for sensitive, integrated genetic and methylation analysis of tumor samples without compromising specificity. The methylation signals separated malignant and benign samples better than traditional approaches, which can often fail to separate cell types.
Illumina Protein Prep allowed the researchers to identify novel gene sets, proteins, and pathways in ovarian cancer, creating new lines of inquiry in cancer biology research, biomarker and drug development. Layering Protein Prep and 5-base data through a custom pipeline in Illumina Connected Multiomics quickly resolved a false positive case.
The layered approach helped researchers establish parameters for targeted exploration of gene expression in spatial data. Using Illumina Spatial Technology, transcriptomic data helped to resolve signals driving false positive results.
Illumina Connected Multiomics accelerates sample-to-answer pipeline
Multimodal analytics from Illumina Connected Multiomics provides deeper insights and overcomes the fragmented, siloed views produced by isolated assays, empowering researchers with a new understanding of cancer mechanisms, tumor heterogeneity, and potential therapeutic targets.
