Scientists Create Synthetic Cell from Scratch
Researchers at the University of Minnesota have built a cell from scratch, called SpudCell, which can feed, grow, and divide without being considered 'alive'. This breakthrough blurs the line between chemistry and biology, with potential implications for fields like biotechnology and medicine.
Key points
- The University of Minnesota team created SpudCell, a synthetic cell made from known chemicals, with a genome of about 90,000 base pairs and 36 purified enzymes.
- SpudCell grows by fusing with 'feeder' bubbles and divides without internal scaffolding, splitting when proteins crowd its surface.
- The team observed competition between SpudCell variants, with a genetic tweak making cells build more of a key protein, leading to faster growth and outcompeting other cells.
- This breakthrough has sparked debate on the definition of life and its implications for biotechnology and medicine, with some experts hailing it as a major achievement.
- The research is still awaiting peer review, with a preprint describing the work and its findings.
Synthetic Cell Breakthrough Blurs Line Between Chemistry and Biology
Researchers at the University of Minnesota have made a groundbreaking discovery by creating a synthetic cell from scratch, dubbed SpudCell. This achievement has significant implications for the fields of biotechnology and medicine, as it challenges the traditional understanding of what constitutes life.
SpudCell is a tiny bubble of lipids wrapped around a genome of about 90,000 base pairs, split across seven strands of DNA. Inside, 36 purified enzymes read the DNA and build proteins, allowing the cell to grow and divide. The team observed competition between SpudCell variants, with a genetic tweak making cells build more of a key protein, leading to faster growth and outcompeting other cells.
This breakthrough has sparked debate on the definition of life and its implications for biotechnology and medicine. While some experts hail it as a major achievement, others argue that SpudCell is not truly alive. The research is still awaiting peer review, with a preprint describing the work and its findings.
The creation of SpudCell opens up new possibilities for the development of synthetic biology and biotechnology. It could lead to the creation of new medicines, biofuels, and other products that are currently difficult or impossible to produce. However, it also raises important questions about the ethics of creating life in a laboratory and the potential consequences of such advancements.
As the scientific community continues to explore the implications of this breakthrough, one thing is clear: the line between chemistry and biology has just gotten a lot thinner.
