Artificial Cell
Artificial cells are synthetic constructs designed to mimic the properties of living cells, ranging from simple lipid vesicles to complex systems capable of metabolism and replication. They serve as foundational models for understanding the origins of life and developing novel biomedical applications.
Key Developments
- Spud Cell: A landmark achievement in synthetic-biology representing the most complete bottom-up artificial cell constructed to date.
- Demonstrates core life processes: eating (nutrient uptake), growing, and replication.
- Detailed in Spud Cell: Bottom-Up Artificial Cell Demonstrating Eating, Growing, and Replication.
Characteristics
- Bottom-Up Construction: Built from non-living components rather than modified existing biological cells.
- Metabolic Activity: Capable of processing external resources to sustain internal functions.
- Self-Replication: Ability to produce copies of itself, a critical threshold for defining artificial life.
