You may have seen the Missouri History Museum’s new “I Am St. Louis” campaign. It celebrates the people, places, and ideas that have shaped our region. It got us thinking: some of the world’s most important human health discoveries and bioscience innovations were born right here in St. Louis — and many of those stories are too often forgotten.
Here are a few medical breakthroughs born in St. Louis that changed the world and still impact lives every day.
Leading the Way in Mapping the Human Genome
In the late 1990s, St. Louis played a leading role in the Human Genome Project, a global effort to map all the genes in human DNA. WashU Medicine was one of the largest contributors to sequencing the human genome, a defining moment in St. Louis bioscience innovation.
How This Breakthrough Transformed Human Health
This breakthrough unlocked an entirely new era of personalized medicine, enabling doctors to better predict disease risk, tailor treatments, and develop gene-based therapies.
Building the Blueprint of Life: DNA and RNA Synthesis
In the 1950s, St. Louis scientists pioneered the biological synthesis of DNA and RNA, revealing how cells build the molecules that carry genetic information – a major human health innovation.
Why This Discovery Still Shapes Biotech Innovation
Their work paved the way for genetic engineering, vaccine development, cancer research, and the creation of mRNA-based therapies like the COVID-19 vaccines that saved millions of lives worldwide.
The First Woman in the World to Win a Nobel Prize in Medicine
In 1947, Gerty Cori became the first woman ever to receive the Nobel Prize in Medicine, making history from right here in St. Louis. Working alongside her husband, Carl Cori, at WashU Medicine, she uncovered how the human body converts sugar into energy — a process now known as the Cori Cycle.
The Lasting Impact on Diabetes and Metabolic Research
Gerty Cori’s work laid the foundation for modern diabetes research and treatment. More broadly, it deepened our understanding of how the body’s metabolism works — knowledge that continues to drive medical breakthroughs in St. Louis and beyond nearly 80 years later.
Unlocking the Power of Vitamin K: A St. Louis Discovery
In 1943, Edward Doisy of Saint Louis University School of Medicine won the Nobel Prize in Medicine for revealing the structure of vitamin K, a nutrient essential to blood clotting.
Why this St. Louis Discovery Still Saves Lives
This discovery revolutionized how doctors treat bleeding disorders and paved the way for important blood-thinning and clotting therapies used every day in hospitals around the world.
Seeing Inside the Body: The PET Scan
Researchers in St. Louis developed positron emission tomography (PET) — a groundbreaking imaging technology that allows doctors to see how organs and tissues are functioning, not just what they look like.
How This St. Louis Innovation Changed Medical Imaging
PET scans are a critical tool for diagnosing cancer, heart disease, Alzheimer’s disease, and more — saving lives through earlier and more accurate detection.
Revolutionizing Medical Imaging: The First X-Ray Contrast Agents
In St. Louis, researchers and industry made significant early contributions to X-ray contrast media (e.g., for gallbladder imaging) many years before PET. (Note: This is often mistakenly described as “inventing the first X-ray” itself, but St. Louis' contributions were in advancing contrast imaging, not the original X-ray discovery.)
Why This Matters Today
These innovations made modern diagnostic imaging possible and remain a cornerstone of radiology and healthcare innovation, from broken bones to heart scans.
Breakthrough Therapies from St. Louis: Celebrex and Beyond
St. Louis' research into inflammation pathways led to the creation of Celecoxib (Celebrex), one of the most widely prescribed anti-inflammatory drugs in the world.
How Bioscience Research Continues to Improve Lives
Celebrex has helped millions of people manage arthritis pain and swelling safely, improving quality of life for patients around the globe.
BioSTL: Carrying the Legacy of Human Health Innovation Forward
These breakthroughs prove that St. Louis has long been a place where human health innovation thrives. While BioSTL wasn’t behind these historic discoveries, for nearly 25 years, we’ve been fueling the next generation of innovators — supporting startups, advancing research, and connecting global ideas to St. Louis.
Today, companies launched and supported by BioSTL are developing breakthrough therapies, curing disease, revolutionizing diagnostics, and reshaping how the world delivers health care.
With the continued support of our community and donors, St. Louis will keep shaping the future of medicine and biotech innovation — just as it has for more than a century.
