Engineering Synthetic Cells through Module Integration and Evolution

Life, the most complex and admirable machine that one could think of has evolved over billions of years to display a beautiful variety of mechanisms that keep cells adapting, self-maintaining, reproducing, and evolving. If we think about it, what is this magic? What are the mechanisms behind life’s origins and wonderful coordination? Attracted...

Expression of a gene-encoded FtsZ-based minimal machinery to drive synthetic cell division

The Christophe Danelon lab is involved in the long-term effort to construct an autonomous minimal cell using a bottom-up approach. Our goal is to achieve self-maintenance, selfreproduction, and evolution of a liposome compartment containing a minimal genome and a cell-free gene expression system. Self-reproduction requires splitting of the...

Genetically encoded phospholipid production for autonomous synthetic cell proliferation

Cells, the building blocks of life, are vastly complex. This complexity confers to every living organism the ability to maintain oneself, reproduce oneself, and evolve. Creating a minimal system from nonliving components that is capable of self-maintenance, self-reproduction, and evolvability, will greatly increase our understanding of life....

Biosynthesis of protein filaments for the creation of a minimal cell

Humanity has achieved to decipher the most fundamental mechanics of cellular life. Nevertheless, despite intense efforts there are still considerable gaps in our understanding of cellular processes. Traditionally, biologists investigate life by observation of existing lifeforms. In order to assign functions to biological components, it is common...

An FtsZ-centric approach to divide gene-expressing liposomes

The creation of artificial cells with the minimal set of components to exhibit self-maintenance, self-reproducibility and evolvability (in other words, to be considered alive) is one of the most exciting areas within the field of synthetic biology. Such entities, here called minimal cells, are constructed by either the top-down or bottom-up...

Synthetic biology meets liposome-based drug delivery

Synthetic biology is an emerging and rapidly expanding field of research focused on the assembly of novel biological systems with new functionalities tailored for different applications. Genetic circuits have been re-wired or constructed with elements from different organisms, and metabolic pathways have been engineered to endow cells with non...
