“Decoding and Recoding Human Tissue Assembly”
The notion of building artificial human organs has moved from a far-fetched concept to the forefront of regenerative medicine research. While progress is being made, most tissues created to date are simply not large enough to support clinically meaningful functions, and their structural features remain an magnitude coarser in resolution than native tissues. Few organs better represent this challenge than the liver – the largest visceral organ in the human body, in which hepatocytes are aligned in single cell-width structures entangled with vascular and biliary networks. To address this challenge, we are working to develop a portfolio of tools that integrate 3D printing, synthetic biology, and the innate capacity of cells to self-assemble. We are applying these tools to decode the signals that drive tissue assembly during development, and using this information to build scaled artificial tissues that replicate the features of native tissues.
