Selfishness versus functional cooperation in a stochastic protocell model [PDF]

open access: yes, 2010
How to design an "evolvable" artificial system capable to increase in complexity? Although Darwin's theory of evolution by natural selection obviously offers a firm foundation, little hope of success seems to be expected from the explanatory adequacy of ...

Predatory behaviour in synthetic protocell communities [PDF]

open access: yes, 2017
Recent progress in the chemical construction of colloidal objects comprising integrated biomimetic functions is paving the way towards rudimentary forms of artificial cell-like entities (protocells). Although several new types of protocells are currently

Protocells: Milestones and Recent Advances

open access: yesSmall, 2022
AbstractThe origin of life is still one of humankind's great mysteries. At the transition between nonliving and living matter, protocells, initially featureless aggregates of abiotic matter, gain the structure and functions necessary to fulfill the criteria of life.

Lipid vesicles chaperone an encapsulated RNA aptamer. [PDF]

open access: yes, 2018
The organization of molecules into cells is believed to have been critical for the emergence of living systems. Early protocells likely consisted of RNA functioning inside vesicles made of simple lipids.

Engineering Protocells: Prospects for Self-Assembly and Nanoscale Production-Lines

open access: yesLife, 2015
The increasing ease of producing nucleic acids and proteins to specification offers potential for design and fabrication of artificial synthetic “organisms” with a myriad of possible capabilities.

Is defining life pointless? Operational definitions at the frontiers of Biology [PDF]

open access: yes, 2016
Despite numerous and increasing attempts to define what life is, there is no consensus on necessary and sufficient conditions for life. Accordingly, some scholars have questioned the value of definitions of life and encouraged scientists and philosophers

From molecular to cellular form: modeling the first major transition during the arising of life

open access: yesBMC Evolutionary Biology, 2019
Background It has long been suggested that Darwinian evolution may have started at the molecular level and subsequently proceeded to a level with membrane boundary, i.e., of protocells.

A spatial model of autocatalytic reactions

open access: yes, 2010
Biological cells with all of their surface structure and complex interior stripped away are essentially vesicles - membranes composed of lipid bilayers which form closed sacs.

Preliminary steps toward artificial protocell computation [PDF]

open access: yes, 2007
Protocells are hypothesised as a transitional phase in the origin of life, prior to the evolution of fully functional prokaryotic cells. The work reported here is being done in the context of the PACE project, which is investigating the fabrication of ...

pH‐Gated Activation of Gene Transcription and Translation in Biocatalytic Metal–Organic Framework Artificial Cells

open access: yesAdvanced NanoBiomed Research, 2021
Regulating gene expression is an important goal for the development of artificial cells that have the ability to replicate the functions of living cells.
