New Synthetic Cells Produced in Laboratory Environment Surprise Scientists

Cells, the basic building blocks of life, are the foundation of the complex functioning of biological systems and must possess the abilities to divide, grow, and reproduce to sustain life. US genetic researchers have announced that they have created the first synthetic cells in a laboratory environment that can complete this vital cycle, meaning they can feed, grow, reproduce, and compete with other species in a controlled environment. Developed by Professor Kate Adamala and her team from Minnesota University and named 'SpudCell', these structures are seen as the greatest progress recorded to date in the field of creating artificial life.

For many years, the science world has aimed to produce a perfect copy of cells in laboratories to examine and modify basic biological principles (such as protein production, division, and growth). While studies in the past were mostly limited to cells that could perform only a single function under very specific conditions, Adamala's team overcame this obstacle and achieved a much more comprehensive success. SpudCells consist of lipid layers (liposomes) that act like a cell membrane, and their interiors are filled with genetic material limited to 36 genes and various chemicals.

The working principle of these artificial cells takes place in an environment where ATP molecules, which provide energy to the cell membrane, are abundant. During the feeding process, small liposomes filled with lipids, ribosomes, and enzymes attach to SpudCells via a protein produced by the cell itself, transferring their contents. The division and reproduction mechanism relies on basic physical rules rather than using a cell skeleton; membrane proteins concentrate, rupturing the cell membrane, and in this way, two new cells containing genetic material are formed.

Researchers also succeeded in giving this system the ability to compete. Within the scope of the experiment, when mutant cells genetically modified to act 'more hungry' were released into an environment containing normal cells, they dominated and took over the environment. However, researchers are cautious about whether SpudCells can be considered fully 'alive' despite all these complex abilities; it is noted that even in the science world, the definition of 'alive' cannot be separated by a clear line.

The reflection of this study in the science world and its approval process is also following a quite striking and at the same time controversial course. The study, which was covered in major publications such as New York Times and The Guardian, has not yet been published in a scientific journal. The study, rejected by the journal 'Cell' on the grounds that it is 'not real biology', is currently published on 'bioRxiv' and awaits feedback from academic circles. While developers plan to submit the study to a new journal soon, they emphasize that the technology obtained could shape the future of biotechnology and bioengineering fields.
