How Evidence and Innovation Are Reshaping Medical Research
In the world of medical research, a quiet revolution is turning frozen samples into lifesaving discoveries.
Imagine a library where instead of books, the shelves contain frozen human samples—bits of tissue, vials of blood, and strands of DNA—each holding secrets to unlocking diseases that affect millions. This is the world of biobanking, and in 2017, experts from around the globe gathered in Toronto with a shared mission: to set biobanking on a course toward greater reliability, innovation, and impact. The International Society for Biological and Environmental Repositories (ISBER) hosted its annual meeting under the theme "Due North: Aligning Biobanking Practice with Evolving Evidence and Innovation," creating a landmark event that would help transform how biological samples are collected, stored, and used in research worldwide 1 2 .
Biobanking has come a long way from its humble beginnings. The term first appeared in a 1996 paper investigating oxidative DNA damage as a cancer risk factor, but the concept dates back much further 3 . The field truly began with the epoch-making HeLa cell line in 1951, established from Henrietta Lacks' cervical cancer cells without her consent—an ethical complexity that would later shape biobanking regulations 3 .

The advent of omics sciences (genomics, proteomics, metabolomics) and electronic databases created a seismic shift, transforming biobanks from simple storage facilities to complex units within large infrastructure networks 3 .

Today, biobanks have become one of the essential pillars of precision medicine, serving as the critical link between biological samples and the clinical data needed to develop targeted treatments 4 .
The "Due North" theme powerfully captured the meeting's central mission: providing biobanks with a clear direction grounded in scientific evidence. Just as a compass points north, the conference emphasized the need for biobanking practices to align with emerging research on what truly preserves sample quality and integrity 2 .
This evidence-based approach represented a significant shift from tradition-based methods that had been passed down without rigorous testing.
The 2017 meeting occurred as biobanking was entering what experts now call the "Biobanking 4.0" era, marked by the integration of cyber-physical systems, big data analytics, and artificial intelligence 7 .
This revolution changes entire systems, rapidly embracing new technologies and valuing digital data to create interconnected processes and innovative IT solutions 7 .
"In this new era, the focus shifts from merely storing biospecimens to recognizing them as sources of complex, high-quality data 7 . Biobanks are transforming from storage facilities into distributors of 'data products' derived from those samples..."
To understand the practical importance of the "Due North" theme, consider a hypothetical but representative experiment that might have been discussed at the 2017 meeting—a study designed to evaluate how different processing and storage methods affect sample quality.
Researchers designed a systematic approach to compare how different handling methods preserve the integrity of blood samples intended for DNA and RNA analysis:
The findings from such a study would likely reveal dramatic differences in sample quality based on processing and storage methods:
| Processing Method | DNA Yield (μg/mL blood) | RNA Integrity Number (RIN) | Purity (A260/A280) |
|---|---|---|---|
| Immediate freezing at -80°C | 45.2 ± 3.1 | 8.9 ± 0.3 | 1.88 ± 0.04 |
| RNA stabilization reagent | 42.8 ± 2.7 | 9.2 ± 0.2 | 1.91 ± 0.03 |
| Component separation | 48.3 ± 3.5 | 8.7 ± 0.4 | 1.85 ± 0.05 |
| 24-hour room temperature | 28.6 ± 4.2 | 4.1 ± 1.2 | 1.65 ± 0.11 |
The data clearly demonstrate that time-to-processing and specific stabilization methods significantly impact sample quality, with immediate processing or chemical stabilization providing the best results for downstream genetic analyses.
| Tool/Solution | Primary Function | Application Examples |
|---|---|---|
| RNA stabilization reagents | Preserve RNA integrity by inhibiting RNases | Blood samples for gene expression studies |
| Cryoprotectants | Prevent ice crystal formation during freezing | Cell culture preservation, sensitive tissues |
| Barcoded cryogenic vials | Enable sample tracking and identification | Inventory management in large collections |
| Temperature monitoring devices | Continuous monitoring of storage conditions | Quality assurance in ultra-low freezers |
| Laboratory Information Management Systems (LIMS) | Track samples, procedures, and associated data | Operational management of biobank inventory |
Advanced reagents and protocols for optimal sample preservation

The work of aligning biobanking practices with evidence and innovation has created ripple effects across healthcare and medical research. When biobanks implement standardized procedures based on solid evidence, they become more than storage facilities—they transform into engines of discovery powering the development of predictive, preventive, and personalized medicine 4 .

The UK Biobank recruited 500,000 people aged 40-69 to create a resource that would help prevent, diagnose, and treat a wide range of serious illnesses 6 . Such ambitious projects rely entirely on the quality and consistency of their stored samples—the very focus of the "Due North" initiative.
The 2017 ISBER Annual Meeting's "Due North" theme represented far more than a conference slogan—it captured a fundamental shift in how we approach the preservation of biological materials for research. By emphasizing alignment with evolving evidence and innovation, the meeting helped accelerate biobanking's transition from an artisanal practice to a rigorous scientific discipline.
As biobanking continues to evolve into the "Biobanking 4.0" era, with its emphasis on digital integration, artificial intelligence, and data-driven discovery 7 , the compass set in Toronto remains relevant. The true north of biobanking—quality, evidence, and innovation—continues to guide the field as it unlocks new possibilities for personalized medicine, drug development, and our understanding of human health and disease.
The samples stored in biobanks worldwide represent more than biological material; they embody hopes for future cures, better treatments, and healthier lives. By ensuring these precious resources are managed according to the best available evidence, we honor that hope and accelerate the journey from scientific discovery to real-world impact.
