About The Cells:
Cells and tissues consist of proteins that collaborate to execute tasks and construct structures. Proteins play a crucial role in establishing the cellular framework known as the cytoskeleton. Without it, cells would be incapable of functioning. The cytoskeleton provides cells with flexibility, enabling them to adapt both in shape and response to their surroundings.
In a recent publication in Nature Chemistry, Ronit Freeman, along with her colleagues from UNC-Chapel Hill, delineate their process of manipulating DNA and proteins, the fundamental components of life, to fabricate cells that closely resemble those found in the human body. Researchers create artificial cells to pioneer the achievement, a breakthrough in the field, that holds promising implications for advancements in regenerative medicine, drug delivery systems, and diagnostic tools.

How Researchers Create Artificial Cells:
| Research | Observation | Conclusion |
| Using an innovative peptide-DNA technology, researchers create artificial cells with functional cytoskeletons capable of morphing and responding to their environment, all without relying on natural proteins. By programming DNA sequences, they orchestrated the assembly of peptides, the basic building blocks of proteins, and repurposed genetic material to construct the cytoskeleton. | DNA typically doesn’t feature in a cytoskeleton. They reprogrammed DNA sequences to function as architectural elements, binding the peptides together. Once immersed in water, these programmed structures took form. | This ability to manipulate DNA empowers scientists to design cells tailored to specific functions and fine-tune their responsiveness to external stimuli. While synthetic cells lack the complexity of their natural counterparts, they offer greater predictability and resilience in harsh conditions, such as extreme temperatures. Synthetic cells remained stable even at temperatures as high as 122 degrees Fahrenheit. |
Researchers create artificial cells By incorporating various peptide and DNA designs, these materials can be programmed to form fabrics or tissues, offering diverse applications across biotechnology and medicine. These advancements in synthetic cell technology hold transformative potential, revolutionizing various fields.
