The world's first synthetic embryo does not require sperm, eggs, nor fertilization, and were grown from only embryonic stem cells (ESCs) or also from stem cells other than ESCs. [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 ...
Biology, being the study of cellular life, addresses reproduction in terms of growth and cellular division (i.e., binary fission, mitosis and meiosis); however, the science of artificial reproduction is not restricted by the mirroring of these natural processes.The science of artificial reproduction is actually transcending the natural forms, and natural rules, of reproduction.
[16] [6] Hanna's complete human stem cell-derived embryo model (SEM) can generate extra-embryonic trophoblast stem cells, mesoderm cells and primitive endoderm cells without genetic modification, transgene or transcription factor over-expression, and has structural and morphological uncanny similarity to day 14 human embryo inside the womb.
That cell, known as a polar body, gives the egg the genetic information it would normally get from sperm. The cell starts dividing and that leads to the creation of an embryo.

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. [3]
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 ...
