Cancer and extracellular vesicles
Extracellular vesicles (EVs) are released or shed by many different cell types and are capable of influencing cellular behaviour and human physiology. EVs are composed of complex molecular signatures of lipids, small molecules, nucleic acids and proteins that can sometimes synergistically elicit physiologically relevant changes in either local or distant cells, tissues and organs. Since exosomes and other classes of EVs (e.g. microvesicles) are emerging as powerful disease biomarkers and as therapeutics they have an enormous potential to transform biomedicine.

cell-free systems and synthetic biology
Cell-free systems that are based on cellular extracts were originally developed as experimental systems to understand fundamental aspects of molecular biology, cellular biochemistry and for in vitro protein production. Synthetic biology approaches are enabling the re-purposing of cell-free systems as coupled in vitro transcription–translation characterisation platforms for the prototyping of DNA based parts, devices and systems. Cell-free transcription-translation systems have been employed to rapidly prototype DNA regulatory elements, logic systems, medical biosensor devices and biomaterials.
