Scientists Create First Synthetic Cell With a Complete Life Cycle, Marking Major Leap Toward Artificial Life
Laboratory-built ‘SpudCell’ can feed, grow, replicate its DNA, and divide—bringing researchers closer than ever to constructing living systems entirely from non-living materials.
Scientists have announced a landmark breakthrough in synthetic biology by creating the world’s first fully synthetic cell capable of completing an entire life cycle, including feeding, growth, DNA replication, and cell division. The achievement, led by researchers at the University of Minnesota, represents one of the closest steps yet toward building life-like systems entirely from non-living chemical components.
The artificial cell, named SpudCell because of its potato-like shape, was assembled from scratch rather than modified from an existing living organism. Unlike previous synthetic biology experiments that relied on natural cells or stripped-down bacteria, SpudCell was built using carefully designed chemical building blocks and a lab-made genome, demonstrating that many essential characteristics of life can emerge without starting from a living cell.
Researchers say SpudCell successfully performs the four fundamental stages of a cellular life cycle: acquiring resources, growing, copying its genetic material, and dividing to produce daughter cells. The team also demonstrated a simple form of natural selection by showing that faster-growing synthetic cells could outcompete others in the laboratory, mimicking one of evolution’s basic mechanisms.
One of the most significant engineering challenges was achieving cell division without the complex internal scaffolding, or cytoskeleton, found in natural cells. Instead, the scientists developed an alternative mechanism in which specialized membrane-associated proteins generate enough mechanical force to split the synthetic cell into two, overcoming a long-standing obstacle in synthetic cell research.
Despite the breakthrough, researchers emphasize that SpudCell is not yet a fully living organism. The synthetic cells still depend on externally supplied molecules, enzymes, and ribosomes to manufacture proteins, and they can reproduce for only a limited number of generations before degrading. In other words, the system remains partially dependent on laboratory support rather than being completely autonomous.
The achievement could have wide-ranging applications in medicine, biotechnology, and sustainable manufacturing. Scientists envision future synthetic cells acting as programmable biological factories capable of producing medicines, vaccines, biofuels, biodegradable materials, and specialty chemicals with greater precision than conventional manufacturing methods. They may also become valuable research tools for understanding diseases and testing new therapies.
Beyond industrial applications, the discovery offers new clues about one of science’s oldest questions: how life first emerged on Earth. By demonstrating that essential life-like behaviors can be reconstructed from non-living chemicals, researchers hope synthetic cells will help unravel the transition from chemistry to biology billions of years ago.
To accelerate progress, the research team has also launched a public-benefit initiative called Biotic, aimed at creating open scientific infrastructure so researchers worldwide can collaborate on developing increasingly sophisticated synthetic cells. While ethical and biosafety considerations remain central to the field, scientists say transparency and international cooperation will be essential as synthetic biology moves closer to constructing fully autonomous artificial life.
