Abstract
In embryos, intrinsic and extrinsic signals cooperatively shape cellular decisions to form tissues and organs. Developmental engineering seeks to harness insights into the molecular mechanisms governing embryonic development and leverage pluripotent stem cells to enable the synthetic reconstitution of organ-like multicellular systems in vitro, including organoids. These cellular systems can partially emulate the complexity of in vivo organs in terms of structure and function, facilitating disease modeling and regenerative medicine applications. Nonetheless, the field faces challenges, such as ensuring reproducibility and achieving adult-level maturation. In this Review, we discuss liver development in the human embryo and current models that are routinely used for generating liver organoids in vitro as well as their limitations. Next, we discuss how synthetic biology and computational analyses can be integrated to enhance organoids, particularly liver organoids, by promoting vascularization, establishing zonation, refining fate specification and enabling responsiveness to external cues. Together, these approaches pave the way for next-generation multicellular human stem cell-derived systems.
