Synthetic Cells That Feed, Grow and Reproduce Created
In a landmark achievement for synthetic biology, researchers at the University of Minnesota have created “SpudCell” — a synthetic cell built entirely from chemical building blocks that can feed, grow, reproduce, and even compete for resources. The breakthrough, announced on July 1, 2026, represents arguably the closest scientists have come to building a living cell from scratch, and it is already reshaping our understanding of what life requires at its most fundamental level.
According to The New York Times, the team led by synthetic biologist Dr. Kate Adamala blended together dozens of ingredients — including a 90,000 base pair genome spread across nine separate DNA molecules, 36 purified enzymes, and a protein expression system — to create simple cells that possess most of the hallmarks of life.
What Is SpudCell?
SpudCell is a liposome — a microscopic bubble made of lipid molecules, the same fatty substances that form natural cell membranes. Inside each bubble is a tiny genome of just 36 genes, dramatically smaller than the roughly 4,460 genes found in E. coli or the 20,000 to 25,000 in humans. In fact, SpudCell’s genome is smaller than the previously theorized minimum of 113,000 base pairs for a living cell.
Dr. Adamala named her creation SpudCell after its potato-like appearance under the microscope — and as a playful nod to Sputnik, the dawn of the space age. “I’m Polish,” she told The Guardian. “I’m mostly made of potatoes.”
How It Works: Feeding, Growth, and Division
SpudCells demonstrate a complete cell cycle through an elegant, simplified mechanism. They absorb small molecules through channels on their surface and fuse with “feeder liposomes” — tiny nutrient-packed bubbles that deliver proteins, ribosomes, and other essential molecules.
A key innovation lies in how SpudCells divide. Natural cells rely on a complex cytoskeleton — internal scaffolding made of dozens of proteins — to pinch themselves in two. Building this from scratch has been a major bottleneck in synthetic cell research. Dr. Adamala’s team bypassed the problem entirely by exploiting a physical principle: when enough proteins accumulate on a membrane surface, the mechanical stress causes the membrane to split.
“But once it works, it works,” Dr. Adamala said.
Evolution in a Dish
Perhaps the most striking demonstration of SpudCell’s capabilities came from a competition experiment. The researchers created a mutant version of SpudCell with a genetic growth advantage and mixed it with original cells in equal proportions. Over five generations, the mutants outcompeted the originals, demonstrating that selection and evolution can operate in a fully synthetic chemical system.
Dr. Roseanna Zia, a computational biologist at the University of Missouri who was not involved in the project, called this “the shake-the-ground accomplishment here.”
Limitations: Not Quite Alive
Despite these remarkable capabilities, the researchers deliberately stop short of calling SpudCell “alive.” The cells have significant limitations: they cannot build their own ribosomes (the molecular machines that produce proteins), they function for only 5 to 10 generations before their machinery degrades, and after five generations only about 30% of daughter cells retain the complete set of DNA plasmids.
“Life is not binary,” Dr. Adamala told the NYT. “That’s why I’m hesitant to call this ‘alive.’ There’s no clear line, as much as we would love it to be.” On SpudCell’s limited lifespan, she added: “I don’t want to say it dies, but it stops working.”
A New Research Organization: Biotic
Alongside the scientific announcement, Dr. Adamala and co-founder Dr. Drew Endy of Stanford University have launched Biotic, a U.S. 501(c)(3) nonprofit research organization dedicated to advancing synthetic cell technology in an open-source, responsible manner. The organization aims to provide open-source protocols and ingredients to researchers worldwide, with the first researchers’ meeting planned for September 2026 in Philadelphia.
Dr. Endy likened SpudCell to a biological version of the Wright flyer: “The Wright flyer flying for 12 seconds doesn’t get you a 737. This is just the beginning.”
Why It Matters
The creation of SpudCell bridges two decades-long approaches to synthetic life. The “top-down” approach, pioneered by the late Craig Venter, starts with living cells and strips away non-essential genes. The “bottom-up” approach starts from individual molecules and tries to assemble a functioning cell. SpudCell is the first system to successfully integrate feeding, growth, division, and evolution using a bottom-up method.
Prof. Tom Ellis of Imperial College London called the work probably the field’s “biggest breakthrough in recent times,” noting that “making a synthetic cell helps us understand the exact minimum requirements for life and how life might have emerged from chemistry.”
What’s Next
The road ahead is clear but challenging. The biggest technical hurdle is enabling SpudCells to build their own ribosomes, which would allow indefinite replication. Dr. John Glass of the J. Craig Venter Institute, who was not involved in the study, expressed confidence: “It’s completely doable.”
Potential applications are vast — from manufacturing novel drugs and proteins that natural cells cannot produce, to carbon capture, to producing rocket fuel. But in their current fragile form, SpudCells remain a research tool rather than an industrial workhorse.
As Biotic prepares for its first meeting this September, the scientific community will be watching closely. Whether SpudCell ultimately becomes the foundation for a new era of bioengineering — or simply a stepping stone to something more capable — one thing is clear: the quest to understand and create life from non-living chemistry has taken a significant leap forward.
