ECTOGENESIS AND THE ARTIFICIAL WOMB. "In 1924, the British scientist J. B. S. Haldane coined the term “ectogenesis” to describe how human pregnancy would one day give way to artificial wombs. A small knot of scientists in the United States and Japan are experimenting with both live animals and human cells to mimic the functioning of the womb." http://lnkd.in/dqMgSUS View in LinkedIn

KID IN ARTIFICIAL WOMB. In 1996, Kuwabara in Japan "reported attempts at preserving a developing goat for three weeks in an incubator that reproduced the uterus and placenta, together with amniotic fluid and blood supply." http://www.nexthumanproject.com/references/Artificial_Wombs_NY_Academy_Sciences.p View in LinkedIn

UTERINE REPLICATORS. "Kuwabara and his associates have kept the goat fetuses in this environment for as long as three weeks. But the doctor's team ran into problems ... Pressed to speculate on the future, Kuwabara cautiously predicts that ''it should be possible to extend the length ... this can be applied to human beings.'' http://lnkd.in/dKqpRBm View in LinkedIn

SURROGATE HYBRID EGG WOMBS. "In 2002, researchers at the Institute of Zoology at the Chinese Academy of Sciences reported the creation of 2,300 hybrid panda-rabbit embryos (produced by inserting panda DNA into enucleated rabbit eggs) and their implantation into rabbit wombs." (Resurrection of extinct species can follow a similar path). http://lnkd.in/dqMgSUS View in LinkedIn

ARTIFICIAL UTERUS. "This can potentially be performed as a switch from a natural uterus to an artificial uterus, thereby moving the threshold of fetal viability to a much earlier stage of pregnancy. In this sense, it can be regarded as a neonatal incubator with very extended functions." http://en.m.wikipedia.org/wiki/Artificial_uterus View in LinkedIn

VORKOSIGAN SAGA VISION OF THE FUTURE. "The uterine replicator ... allowed unborn human fetuses to be gestated in vitro, rather than in a woman's body. 'Gene-cleaning' was a major use of the replicator. Defects in the zygote could be looked for and eliminated prior to birth, removing any genetic problems, such as diseases or inherited traits (like a weak heart)." http://lnkd.in/d7pDnZ6 View in LinkedIn

SHARK ARTIFICIAL UTERUS. "Otway conducted the first trial of the acrylic uterus with 10-month-old embryos from a pregnant wobbegong shark ... He replicated a shark's uterus by bathing the embryos in 68˚F seawater. After 17 days, the fake womb "gave birth" to six healthy pups." http://lnkd.in/dCjMrST View in LinkedIn

VIABLE MOUSE WOMB ON HORIZON. "In 2002 she and her colleagues started making mouse wombs and growing mouse embryos inside them. . . . Liu thinks she and her team should have a viable mouse womb in 5 to 10 years. A human model will take longer – “10 years, maybe, or a little more,” she says, assuming that restrictions on fetal testing are lifted or eased." http://www.nrlc.org/archive/Killing_Embryos/ArtificialWombs.html View in LinkedIn

AUTOLOGOUS CULTURED WOMBS, using endometrial cells taken from a woman's body, and cultured on a scaffold, permit human embryo implantation, ex-vivo,in a bath of chemicals, hormones and growth factors. http://lnkd.in/dWnXFkS View in LinkedIn

IVF WOMB ON CHIP. "Teruo Fujii and his colleagues believe their "womb-on-a-chip" is superior to growing embryos in the static environment of a Petri dish, the way in-vitro fertilization clinics now prepare embryos for implantation into a mother's womb. Eventually, they hope it will lead to better outcomes for infertile women." http://lnkd.in/defcr2P View in LinkedIn
