Artificial embryo samples aboard Tiangong Space Station for life science research Space "artificial embryo" samples and other life science experiments delivered by the Tianzhou-10 cargo spacecraft have been installed into experiment modules aboard China's Tiangong space station, the Technology and Engineering Center for Space Utilization under the Chinese Academy of Sciences (CAS) said on Wednesday. The "artificial embryos" are stem cell-derived artificial human embryos. The embryos, though not true life forms and unable to develop into human babies, will help simulate the earliest stages of human development. Once the experiments are completed, the artificial embryo samples will be frozen in orbit and then returned to Earth on a future mission for side-by-side analysis with ground-based controls in laboratories on the ground. This effort is part of a broader suite of 41 space science experiments being deployed aboard Tiangong, supporting its latest round of research on the orbiting laboratory.
