Scientists may have just crossed one of biology’s biggest lines.
Researchers at the University of Minnesota say they have built a synthetic cell from non-living chemical ingredients that can feed, grow, copy its genome, divide, and reproduce across multiple generations.
They call it SpudCell.
The team says it is the first synthetic cell with a complete cell cycle. That means it does not just sit in a lab dish. Under the right conditions, it can take in nutrients, grow larger, replicate its genetic material, split into daughter cells, and continue the process for about five generations.
That is a major step toward one of biology’s biggest goals: building life-like systems from scratch.
But SpudCell is not exactly “alive” in the way bacteria, plants, or animals are alive.
It is extremely simple, made from roughly 150 to 200 molecules. A natural cell can contain billions. It also cannot make its own proteins, so scientists still have to feed and maintain it. To divide about once every 12 hours, it must be kept at 86°F (30°C) and supplied with outside materials.
For comparison, E. coli bacteria can divide about every 30 minutes.
Still, the breakthrough matters because the cell is fully defined. Researchers know its ingredient list, which could make it easier to engineer biology in precise ways.
In the future, synthetic cells could potentially be designed to deliver medicine, help fight cancer, clean pollution, capture carbon, or manufacture useful materials. They could also help scientists answer one of the deepest questions in science: what is the minimum recipe for life?
Experts are divided on whether SpudCell should be called a living organism. Some say it is closer to life than anything built before. Others argue it is still too dependent on human care to count as true life.
