Scientists Engineer First Synthetic Cell Powered by Man-Made DNA

The project represents a definitive shift in the boundary between chemistry and biology. By packing non-living molecules into an artificial membrane, the researchers observed the inert mixture spontaneously adopting the behaviors of a living entity. Unlike natural organisms with massive genomes, SpudCell operates on a streamlined 90-kilobase-pair genome, with its genetic data partitioned across seven distinct DNA plasmids. This modular architecture functions like a smartphone operating system, allowing scientists to program specific cellular behaviors independently.

To sustain the cell, the team modified specialized proteins within its lipid membrane to facilitate feeding through nutrient-filled bubbles known as liposomes. When these bubbles collide with the cell, they fuse and inject fuel directly into the interior. In the absence of a natural cytoskeleton, the cell achieves division through a programmed mechanical process. It produces specialized proteins that crowd the inner membrane, creating sufficient physical pressure to force the cell to pinch and split into two. Adamala, who plans to submit the research for peer review shortly, characterizes the organism as a nascent, functional system capable of eating and reproducing.
