The genetic “BOOST” strategy integrates tissue engineering and synthetic biology tools to enable on-demand liver growth inside the body. By specifically rewiring the gene expression of primary liver hepatocytes and supportive fibroblast cells, a tissue growth program is switched on in a small, engineered liver construct after its implantation into recipients and upon addition of an inducing agent (shown as a pill). As a result, the hepatocytes in the construct start and continue to proliferate until a desired construct size has been reached and the inducing signal is not provided anymore. In mice, BOOST resulted in robust and healthy liver growth.
