Biotic, Minnesota Team Build 90,000-Base-Pair SpudCell With First Full Synthetic Cell Cycle
3 articles · Updated · Nautilus · Jul 3
Summary
Biotic and University of Minnesota researchers said SpudCell, assembled entirely from purified non-living components, fed, copied its DNA and reproduced for about five generations.
The system combines a 90,000-base-pair genome spread across plasmids, 36 enzymes and a simplified lipid membrane, making it the first bottom-up synthetic cell reported to complete a full cell cycle.
The result remains provisional because the manuscript is unpublished and not yet peer reviewed, and outside scientists said the advance does not yet amount to lab-created life.
SpudCell contains only about 200 molecules, needs tightly managed nutrient inputs and falls far short of the complexity and open-ended reproduction seen in living cells, though it could advance synthetic biology and future biomanufacturing.
A new cell can eat, grow, and evolve. Where is the line between a complex chemical machine and a living thing?
As the recipe for synthetic life goes open-source, who decides when scientific ambition has gone too far?
Why is the creator of a new synthetic cell now warning that a related technology could unleash an 'unstoppable plague'?
Building Life from the Ground Up: SpudCells and the Future of Synthetic Biology
Overview
On July 1, 2026, Dr. Kate Adamala's team at the University of Minnesota introduced SpudCells, a groundbreaking form of synthetic life. These synthetic cells are built from nonliving components and can feed, grow, and reproduce for several generations. Scientists achieved this by constructing a cell from scratch that shows the basic hallmarks of life, marking a major shift in how we understand and create life-like systems using a bottom-up approach. SpudCells have a much smaller genome than natural cells, yet they are able to replicate, highlighting a new frontier in synthetic biology.
