Key Takeaways
University of Minnesota researchers unveiled SpudCell on July 1, the first synthetic cell built entirely from non-living chemicals that runs a complete life cycle.
SpudCell feeds, grows, copies its own genome, and divides on its own, and a faster-growing version outcompeted the original after five generations.
Its genome is just 90 kilobase pairs across seven DNA plasmids, and the team launched a nonprofit called Biotic to keep the platform open.
On July 1, researchers at the University of Minnesota said they built a cell from scratch that behaves like a living one. It feeds, it grows, it copies its own genome, and it divides into two. They call it SpudCell, and they assembled it from non-living chemical parts instead of editing an existing organism.
That last point is what sets it apart. For years the field could copy single features of life in a dish, and in 2010 Craig Venter's team booted up a synthetic genome inside a hollowed-out bacterium. SpudCell is the first to run the full set of cell behaviors in a system built entirely from chemistry, according to the university's research brief and a new paper covered by Science and Quanta Magazine.
The details are striking. SpudCell divides without a cytoskeleton, the internal scaffolding that has long stalled this work, by letting proteins crowd the membrane until the mechanical stress splits it. Its genome runs to about 90 kilobase pairs across seven plasmids, smaller than the 113 kilobase floor biologists once guessed a living cell would need. When the team added a genetic tweak that sped up growth, the faster version outcompeted the original after five generations, which is selection and competition running in pure chemistry.
"We've replicated in chemistry what only used to be possible in biology"

None of this is a finished tool. The cells are fragile, depend on a lab fluid, and cannot yet evolve, and the seven plasmids still need to be consolidated into one genome. The team launched a nonprofit called Biotic to keep the standards open rather than locked behind a single lab. WYDE has followed this frontier before, from a biotech that says it made the first human eggs from stem cells to an AI model that designs drug molecules for any protein pocket. SpudCell is the platform underneath. Worth watching.
People Also Ask
What is SpudCell?
SpudCell is a synthetic cell built by University of Minnesota researchers from non-living chemical components. It is the first lab-made cell to feed, grow, replicate its genome, and divide on its own.
Did scientists create life from scratch?
They built a cell that carries out the core functions of life, including feeding, growth, and division, from non-living parts. Researchers call it a major engineering milestone, though the cells remain fragile and cannot yet evolve.
How is SpudCell different from earlier synthetic cells?
Earlier milestones, such as Craig Venter's 2010 work, placed a synthetic genome inside an existing cell. SpudCell was assembled entirely from chemistry and runs a complete life cycle without borrowing a living host.
What could synthetic cells be used for?
The team says cells built from scratch could make medicines and materials that standard chemistry cannot, and do it at biological temperatures rather than industrial ones. Those uses are still years away.
