A team at the University of Minnesota has produced a synthetic cell-like system assembled entirely from purified chemical components. Named SpudCell, it completes a full cycle of feeding, growth, genome replication and division, marking a notable step in efforts to understand life's core mechanisms through evidence-based inquiry.
The system, detailed in a preprint posted on bioRxiv on 1 July 2026, relies on lipids, a 90,000 base pair genome spread across seven or nine DNA plasmids, 36 enzymes from the PURE protein synthesis mixture, and additional molecular machinery. All components start from non-living sources. This approach contrasts with methods that begin by stripping genes from existing organisms and offers precise control over every part.
SpudCell feeds by fusing with separate nutrient-carrying liposomes, grows, copies its genetic material, and splits into daughter cells. Division occurs through the crowding of membrane proteins that create mechanical stress, without any reconstituted cytoskeleton. Over successive generations, variants that feed more effectively outcompete others, showing a basic form of selection. The work was led by Associate Professor Kate Adamala.
This is likely the most exciting project I have ever worked on. We have replicated in chemistry what only used to be possible in biology: the complete set of behaviours of a cell. It proves that the most fundamental functions of life, like growth and replication, do not need a mysterious magical spark.
Adamala's words capture the significance. The system is not considered a living organism by its creators, yet it performs behaviours once thought exclusive to natural cells. It operates for roughly five to ten generations before external ribosomes supplied in the mixture degrade, as the current genome cannot yet direct their own production.
Such research underscores the strength of unfettered academic investigation. Free from ideological overlays, it channels individual curiosity and institutional initiative into concrete advances. The resulting knowledge strengthens a nation's capacity for innovation, opening pathways that markets can later turn toward practical uses in medicine, materials science, industrial chemicals and deeper study of life's origins.
Alongside the scientific release the team established Biotic, a public-benefit body intended to develop shared open infrastructure for synthetic cell engineering. This move aims to encourage collaborative refinement of the platform worldwide.
