SpudCell: First Synthetic Cell With a Complete Life Cycle Built From Scratch

For the first time, scientists have built a synthetic cell entirely from non-living chemical components that can feed, grow, and reproduce through multiple generations — a landmark achievement in synthetic biology that brings us closer to engineering life from scratch.

• SpudCell, developed by University of Minnesota researchers Kate Adamala and Aaron Engelhart, is a cell-like system constructed entirely from known chemical components. Its genome is just 90 kilobase pairs — roughly 30,000 times smaller than the human genome — yet it performs a complete cell cycle including growth, DNA replication, and division.
• The synthetic cells absorb nutrient packets from their environment, merge with them to grow in size, and then split into two daughter cells. Each new cell can repeat the cycle across multiple generations, demonstrating the first fully synthetic system capable of sustained reproduction.
• Beyond its scientific significance, SpudCell opens practical pathways for engineered biology — from manufacturing rare pharmaceutical compounds and bio-sensing environmental toxins to creating on-demand biomaterials for space missions, where transporting living cells is impractical.
