Making embryos: a new way? Appeared in BioNews 1091 Recently there have been some phenomenal reports describing the ability to generate human embryo-like entities directly from stem cells, circumventing the need for egg and sperm. In the same week, researchers from Israel reported the development of post-implantation mouse embryos outside of the uterus to the mid-point of mouse pregnancy; an achievement previously firmly within the realm of science fiction. The work is clearly at the leading edge of cell and developmental biology and challenges the paradigms of what it takes to create an embryo. However, like many ground-breaking studies, it is essential to reflect on what lies beneath. ....
E-Mail To observe how a tiny ball of identical cells on its way to becoming a mammalian embryo first attaches to an awaiting uterine wall and then develops into nervous system, heart, stomach and limbs: This has been a highly-sought grail in the field of embryonic development for nearly 100 years. Prof. Jacob Hanna of the Weizmann Institute of Science and his group have now accomplished this feat. The method they created for growing mouse embryos outside the womb during the initial stages after embryo implantation will give researchers an unprecedented tool for understanding the development program encoded in the genes, and it may provide detailed insight into birth and developmental defects as well as those involved in embryo implantation. The results of this research were published in ....

Prof. Jacob Hanna of the Weizmann Institute of Science and his group have now accomplished this feat. The method they created for growing mouse embryos outside the womb during the initial stages after embryo implantation until more advanced stages will give researchers an unprecedented tool for understanding the development program encoded in the genes, and it may provide detailed insight into birth and developmental defects as well as those involved in embryo implantation. The results of this research were published in Nature. ....
