The vision for Edinburgh's Centre for Mammalian Synthetic Biology (SynthSys-Mammalian) is to pioneer the development of the underpinning tools and technologies needed to implement engineering principles and realise the full potential of synthetic biology in mammalian systems. We have an ambitious plan to build in-house expertise in cell engineering tool generation, whole-cell modelling, computer-assisted design and construction of DNA and high-throughput phenotyping to enable synthetic biology in mammalian systems for multiple applications. In this way we will not only advance basic understanding of mammalian biology but also generate tools and technologies for near-term commercial exploitation in areas such as the pharmaceutical and drug testing industries, biosensing cell lines sensing disease biomarkers for diagnositics, novel therapeutics, production of protein based drugs e.g. antibodies and also programming stem cell development and differentiation for regenerative medicine applications. In parallel we will develop and implement new understanding of the social and economic impact of this far-reaching technology to ensure its benefits to society.
