Building Synthetic Cells─From the Technology Infrastructure to Cellular Entities

Area of Science:

• Synthetic biology
• Origin of life research
• Cellular engineering

Background:

• The creation of a living organism from scratch remains a significant scientific challenge.
• Existing technologies allow for cell modification but not complete de novo construction.
• The pursuit of this goal drives advancements in diverse scientific fields.

Purpose of the Study:

• To review current efforts in building artificial cells.
• To distinguish between various approaches to de novo cell construction.
• To identify key challenges and propose a roadmap for future research.

Main Methods:

• Analysis of different methodologies for creating life-like systems.
• Identification of bottlenecks in current de novo cell construction research.

Main Results:

• Significant progress has been made in synthesizing individual life characteristics (e.g., compartmentalization, metabolism, replication).
• Limited combinations of life criteria have been achieved in artificial systems.
• Key bottlenecks hindering complete de novo cell construction have been identified.

Conclusions:

• Building a functioning cell from molecular parts is an ongoing challenge.
• A structured roadmap with key milestones is proposed to guide future research.
• Continued research promises profound insights into cell biology, biotechnology, and astrobiology.
