Bioengineered liver and kidney tissue constructs will be sent to space to assess the impact of microgravity on vascularization of thick tissues. If successful, this platform technology and approach could lead to the in-space bioengineering of 鈥榖uilding blocks鈥 of tissue that can serve as a bridge to transplants in patients awaiting a limited supply of donor organs. This project is part of the 不良研究所 collaboration with Wake Forest Institute for Regenerative Medicine and the ReMDO to develop an In-Space Biomanufacturing Hub for regenerative medicine.
