[8] The structure had an intestinal tract, early brain, and a beating heart and a placenta with a yolk sac around the embryo. [8]
Scientists in Israel have created a model of a human embryo from stem cells in the laboratory, without using sperm, eggs or a womb, offering a unique glimpse into the early stages of embryonic ...
To achieve this, he first developed a technique for extended culturing mouse embryos outside the uterus (ex utero) in 2021 capturing development from before gastrulation until late organogenesis outside the uterus, [7] [8] subsequently applying his technique for making the first synthetic complete embryo models of mice in 2022, [5] [9] [10] and ...

The "embryos" grew placentas and organs and could be used for research. We're still a long way before we can make humans embryos that way. In world first, artificial mouse 'embryos' were grown ...
Figure from a 2017 Nature Communications paper describing an extra-uterine life support system, or "biobag", used to grow lamb fetuses. [1]An artificial womb or artificial uterus is a device that would allow for extracorporeal pregnancy, [2] by growing a fetus outside the body of an organism that would normally carry the fetus to term.
