Cloned early-stage human embryos¿and human embryos generated only from eggs, in a process called parthenogenesis¿now put therapeutic cloning within reach
Two papers in Nature now make key advances in this field, showing that human embryonic stem cells2 or cells reprogrammed from adult tissues2,3 can be induced to self-organize in a dish, forming structures that resemble early human embryos. This is the first integrated human embryo model ...
Early in development, human embryos form a structure called the blastocyst. Two research groups have now generated human blastocyst-like structures from cells in a dish, providing a valuable model for advancing human embryology.#Generation of human blastoids from cells in vitro....
Gap junctions have been identified between cells in late passage cultures of human embryo fibroblasts using techniques of freeze-fracture and electron microscopy. The junctions are sparsely distributed, which may suggest a decrease in el... RO Kelley - 《Mechanisms of Ageing & Development》 被引量...

Remodelling of the human embryo at implantation is indispensable for successful pregnancy. Yet it has remained mysterious because of the experimental hurdles that beset the study of this developmental phase. Here, we establish an in vitro system to
First man to live without a heart dies ByRJonOctober 19, 2012•(Leave a comment) google.com (AFP) Czechs on Thursday mourned the death of Jakub Halik, a 38-year-old fireman, who became the first human ever to have survived six months without a heart on artificial life support, but ...
in Israel, published papers describing mouse embryoids withrudimentary guts, brains and beating hearts. In June Dr Zernicka-Goetz published a paper describing a human embryoid designed to mimic the earliest stages of development, shortly after a real embryo would have implanted into its mother’s...
One year's experience with elective transfer of two good quality embryos in the human in-vitro fertilization and intracytoplasmic sperm injection programmes. The embryo development is similar for zygotes obtained after IVF and ICSI; for both techniques 63% of the zygotes develop to type A-B ...
