Scientists have achieved a major breakthrough in understanding life by creating simple, manmade cells that feed, grow, reproduce, and compete with each other. Led by Kate Adamala at the University of Minnesota, the team synthesized these cells using dozens of ingredients and demonstrated their ability to evolve over time.
The creation, called SpudCell, lacks some essential features of natural cells but exhibits many characteristics of life. Dr. Adamala’s goal was not to create a living cell but rather to simplify the process and better understand the fundamental mechanisms of life. The team used a combination of proteins and simple molecules to create the soup-like mixture that eventually formed the SpudCells.
The researchers added genes from viruses and bacteria, allowing the cells to carry out basic chemical reactions. They also provided the cells with food through channels on their surfaces, enabling them to feed and grow. As the cells fed, they divided into two new cells, demonstrating a rudimentary ability to evolve.
While SpudCells still have limitations, such as not being able to produce ribosomes, which are crucial for protein synthesis, this achievement marks an exciting step forward in understanding life’s complexity. The creation of these simple cells has also sparked the idea of using synthetic cells to develop new medicines and technologies in the future.
Dr. Adamala is now working with a nonprofit organization called Biotic, which aims to create a community of SpudCell researchers who can collaborate on building more sophisticated versions of the cells.
