For first time, a cell built from scratch grows and divides
A Breakthrough in Synthetic Biology: The First Lab-Grown Cell That Divides
By Yasemin Saplakoglu | July 1, 2026
In a landmark achievement for synthetic biology, researchers have successfully assembled a synthetic cell from nonliving parts that exhibits more lifelike behaviors than any previous attempt. This proof of concept suggests that it is indeed possible to bridge the gap between inert matter and biological life within a laboratory setting.
For the first time, scientists meticulously packed a membrane with nonliving molecular components, creating a "bag of molecules" that began to function like a living organism. Specifically, this artificial cell was able to grow, duplicate its genetic material, and split into daughter cells, effectively mimicking the fundamental stages of a cellular life cycle.
"I don’t know of any other effort to put together an artificial cell from biological components that has progressed so far," noted Jack Szostak of the University of Chicago, an expert in the origins of life who was not part of the study.
Is it Actually "Alive"?
While the achievement is staggering, the cell is fully alive not alive by strict biological definitions. It lacks autonomy and depends entirely on the researchers for survival.
Comparison: Synthetic vs. Natural Cells
| Feature | Synthetic Cell (Adamala Lab) | Natural Biological Cell |
|---|---|---|
| DNA Replication | Yes | Yes |
| Cell Division | Yes | Yes |
| Metabolism | No (Requires external feed) | Yes (Self-sustaining) |
| Protein Synthesis | Yes (Via added ribosomes) | Yes (Internal machinery) |
| Autonomy | Low | High |
Because it requires a constant supply of "food" and ribosomes (the cellular factories that produce proteins), it remains a sophisticated chemical system rather than a self-sufficient organism. However, Sijbren Otto, a systems chemist at the Stratingh Institute, describes it as a "big step forward" toward the "holy grail" of creating life from dead components.

The Blueprint for Artificial Life
Kate Adamala, a synthetic biologist at the University of Minnesota, approached the project as an engineering challenge. Since every component was manufactured in the lab, the team possesses a complete chemical ingredient list and a precise blueprint, allowing them to swap parts and optimize the system.
The "Life" Checklist
To build the cell, Adamala focused on the universal requirements of all known life:
- Containment: A lipid membrane to hold materials.
- Information: A genome to provide instructions.
- Transcription: Converting DNA to RNA.
- Translation: Converting RNA to proteins.
- Replication: Copying DNA for the next generation.
- Division: Splitting into two separate entities.
The Technical Process
The team utilized liposomes—hollow spheres made of lipids—as the cell's outer shell. The internal "soup" was a carefully tuned mixture of:
- A DNA Replication System: Based on work by Hannes Mutschler and Christophe Danelon.
- Protein Machinery: A commercial kit containing 36 different enzymes responsible for reading DNA and synthesizing proteins.
- External Support: Since the synthetic genome lacked metabolic genes, the researchers manually added sugars, lipids, and enzymes to other liposomes to sustain the system.
The central dogma of this synthetic cell follows the standard biological flow:

Why This Matters
This research does more than just mimic life; it provides a platform for extreme experimentation. By tinkering with the biological "code," scientists can explore:
- Industrial Applications: Engineering cells to produce novel drugs or biofuels.
- Medical Research: Using simplified models to study how diseases attack cells.
- Existential Questions: Investigating abiogenesis (how life first emerged 4 billion years ago) and determining the absolute minimum requirements for life to exist.
While other institutions, such as the Craig Venter Institute, focus on stripping existing bacteria down to a "minimal genome," Adamala's "bottom-up" approach asks a more provocative question: "What else can biology do?"
