Question 9: Prospects for the Construction of Artificial Cells or Protocells

The construction of artificial cells or protocells that are a simplified version of contemporary cells will have implications for both the understanding of the origins of cellular Life and the design of “cell-like” chemical factories. In this short communication, we discuss the progress and remaining issues related to the construction of protocells from metabolic products. We further outline the de novo design of a simple chemical system that mimics the functional properties of a living cell without being composed of molecules of biological origin, thereby addressing issues related to Life’s origins.
