Part 5/6:
Despite the promising developments, several hurdles remain. The synthesized mini livers may not yet match the full functionality or longevity of a natural liver. Additionally, managing immune rejection and ensuring consistent growth and integration of the mini livers are ongoing challenges for scientists.
Nonetheless, this innovation opens new avenues in regenerative medicine. If perfected, growing mini livers within patients could serve as a critical bridge or temporary solution for those awaiting transplantation, potentially saving lives and reducing the dependence on donor organs.
