Scientists at the University of Minnesota have built a synthetic cell capable of feeding, growing, copying its DNA, and dividing [1, 2].
The development represents a significant step toward the goal of creating artificial life in a laboratory setting. By replicating these fundamental biological processes, researchers hope to better understand how life first originated and how to design controllable biological systems [1].
The synthetic cell, referred to as SpudCell, demonstrates several key characteristics of living organisms. It can intake nutrients to sustain its growth and replicate its genetic material to facilitate division [1, 2]. This capability allows the artificial structure to mimic the basic lifecycle of a natural cell.
However, the achievement has sparked a debate over the definition of life. While the researchers highlighted the cell's ability to perform these functions, other reports indicate that the project falls short of creating true life [1]. The distinction rests on whether a synthetic entity can be considered alive if it lacks the full complexity and autonomy of naturally evolved organisms.
The research team focused on creating a system where biological components are assembled from the ground up. This approach differs from traditional genetic engineering, which typically modifies existing living cells. By building a cell from synthetic parts, the scientists aim to isolate the minimum requirements necessary for a system to exhibit life-like behavior [1].
University of Minnesota scientists said the project is part of a broader effort to advance synthetic biology. The ability to create and control these cells could eventually lead to new methods for producing medicines or cleaning environmental pollutants [1].
“Scientists have built a synthetic cell that can feed, grow, copy its DNA, and divide.”
This development highlights the narrowing gap between biological organisms and engineered systems. While SpudCell does not meet the full scientific criteria for 'life,' the ability to synthesize a dividing cell suggests that the fundamental mechanisms of biology can be replicated artificially. This moves the field of synthetic biology from modifying existing life toward the potential for designing entirely new biological entities.
