Ethical issues in human organoid and gastruloid research.
Research involving human organoids and gastruloids involves ethical issues associated with their derivation as well as their current and future uses. These include unique issues related to the extent of maturation that can be achieved in vitro or through chimeric research, as well as fundamental ethical considerations such as those concerning the provenance of human biomaterials and the use of gene-editing technologies. Many of these issues are not specifically addressed by existing ethics oversight mechanisms, but these mechanisms might be easily extended to help ensure that human organoid and related research moves forward in an ethically appropriate manner.
