What's Happening?
Researchers at the Institute for Bioengineering of Catalonia (IBEC) have successfully created an artificial cell that can navigate its environment using chemical signals, similar to living cells. This development, published in Science Advances, involves a 'minimal cell' designed as a lipid vesicle containing enzymes that enable chemotaxis, a process where cells move toward beneficial substances or away from harmful ones. The study highlights the potential of synthetic biology to replicate complex biological processes with simpler systems, providing insights into cellular transport mechanisms. The artificial cell mimics natural chemotactic behavior without the need for complex machinery like flagella, using a combination of liposomes and pore proteins to facilitate movement.
