Professor W. Benjamin Rogers in the Department of Physics has been awarded a 2020 Human Frontier Science Program (HFSP) collaborative Program Grant to create a self-propagating synthetic cell. The HFSP Program Grants aim to tackle big questions in the life sciences by supporting and bringing together researchers with different backgrounds from different countries. Professor Rogers’ team grant was one of 20 successful Program Grants that went through a year-long global selection process.
The project aims to build a stably-propagating cell from simple components. The cell will have a lipid membrane encapsulating DNA and transcription-translation machinery, and be able to grow and divide by internally synthesizing its own membrane material.
The project is significant because a stably propagating cell is a vital element of natural selection. Extant life on Earth is a consequence of natural selection acting upon earlier forms of life, shaping the lineages over time. Thus at some point early in life’s origins, a sustainably propagating cell must have emerged, allowing selective advantages to accumulate over successive generations. For daughter cells to have retained the attributes of their parent, both the genetic information and the cell contents must have been replicated with reasonable fidelity. However, it is currently unclear how controlled cell division could have first emerged from relatively simple molecules. It is precisely this mystery that the team hopes to understand by attempting to recreate it in a test tube.
Professor Rogers’ grant is shared with Dr. Yutetsu Kuruma from Japan Agency for Marine-Earth Science and Technology and Professor Anna Wang from University of New South Wales in Australia.
