The ability to synthesize cells from scratch or redesign existing ones opens new frontiers in understanding cellular mechanisms, advancing medical therapies, and developing novel biotechnological applications. The journey towards cell synthesis began with foundational studies in cellular biology and molecular genetics, where early researchers explored cell function, structure, and the genetic code. Initial efforts were focused on understanding how cells operate and interact with their environment. The introduction of genetic engineering techniques in the late 20th century marked a significant milestone, allowing scientists to manipulate cellular DNA and proteins with unprecedented precision. This laid the groundwork for more ambitious projects in cell synthesis [1].

The development of synthetic biology in the early 2000s marked a turning point, enabling the design and creation of new biological systems and organisms. Researchers began to envision the possibility of constructing cells from scratch or redesigning existing cells to perform specific functions. This period saw the rise of key concepts such as standardized biological parts (BioBricks) and modular design principles, which have since become integral to the field of cell synthesis. This interdisciplinary field aims to design and construct new biological parts, devices, and systems. By leveraging principles from engineering and biology, synthetic biology facilitates the creation of cells with novel functions or improved capabilities. Synthetic biology encompasses a range of techniques, including gene synthesis, genetic circuit design, and the assembly of biological components [2].

Historically, cell synthesis has its roots in early efforts to manipulate and study cellular components. With the advent of synthetic biology and advances in genetic engineering, researchers have gained unprecedented control over cellular processes.
