  • world's
  • So far this has only ever been achieved with animals, most famously Dolly the sheep, born on July 5, 1996, who was the world's first animal mammal cloned from an adult cell (Moore 5). (scribd.com)
  • On November 2015, a Chinese biotech company Boyalife Group announced that it will partner with Hwang's laboratory, Sooam Biotech, to open the world's largest animal cloning factory in Tianjin as early as 2016. (wikipedia.org)
  • In 1998 he applied to study for a Ph.D. in biology at the Massachusetts Institute of Technology, arriving there shortly after Dolly the Sheep gained worldwide attention as the world's first cloned domestic animal. (wikipedia.org)
  • donor
  • The skin cell nucleus was then fused with the donor egg cell. (www.nhs.uk)
  • To create a clone, a scientist removes the nucleus from a donor cell, then places it into an egg from which the nucleus has been removed. (eurekalert.org)
  • They used a bit of skin from each man, took the DNA from the skin cells and inserted it into the egg cell of a female donor, and grew very early embryos called blastocysts, the team reports in the journal Cell Stem Cell. (bioethics.net)
  • In somatic cell nuclear transfer ("SCNT"), the nucleus of a somatic cell is taken from a donor and transplanted into a host egg cell, which had its own genetic material removed previously, making it an enucleated egg. (wikipedia.org)
  • The technique consists of taking an enucleated oocyte (egg cell) and implanting a donor nucleus from a somatic (body) cell. (wikipedia.org)
  • The nucleus of the donor egg cell is removed and discarded, leaving it 'deprogrammed. (wikipedia.org)
  • Expertise in human egg biology led Kiessling to develop the country's first human egg donor program for stem cell research in 2000. (wikipedia.org)
  • Texas A&M University cloned a Black Angus bull named 86 Squared in 2000, after cells from his donor, Bull 86, had been frozen for 15 years. (wikipedia.org)
  • Researchers
  • It should be noted that no babies were born as a result of this research, and the researchers had no intention of producing a live cloned human being. (www.nhs.uk)
  • Researchers have been looking into ways of using a patient's own cells to create embryonic stem cells, as this would ensure that the genetic material in any cells used therapeutically would match the patient's DNA. (www.nhs.uk)
  • The researchers report that previous attempts to produce embryonic stem cells using this technique have failed, as the cells stopped dividing before they reached an advanced enough stage. (www.nhs.uk)
  • This study will no doubt be very exciting for researchers working with stem cells, but we're still a long way from the findings of this study being translated into new treatments for conditions such as Parkinson's disease or heart disease . (www.nhs.uk)
  • The researchers used a technique called somatic cell nuclear transfer (SCNT) to transfer genetic material from adult human skin cells into a human egg cell in order to produce embryonic stem cells. (www.nhs.uk)
  • Researchers then optimised methods to prompt the egg cell to start and continue to divide using electricity and chemical compounds, including caffeine. (www.nhs.uk)
  • The news that South Korean researchers have become the first to produce human embryos and stem cells through cloning has revived a complex debate about whether such research should be permitted in the United States. (nytimes.com)
  • The researchers showed that the resulting embryos could develop to a stage where they could produce healthy stem cells containing the genes from the skin cells. (kwit.org)
  • Researchers have tried to test the integrity of these surviving stem cells by transplanting them into fertilized blastocysts and then observing the overall health of the resulting animal. (eurekalert.org)
  • But since the human cells used in the study appeared even more fragile, researchers said it was unlikely that clones could be made. (abc.net.au)
  • Researchers say other stem cell sources may be easier and less controversial. (abc.net.au)
  • NBC News ] Researchers say they have made powerful stem cells from both young and old adults using cloning techniques, and also found clues about why it is so difficult to do this with human beings. (bioethics.net)
  • In this experiment, the researchers developed a protocol for using SCNT in human cells, which differs slightly from the one used in other organisms. (wikipedia.org)
  • Based on meticulous mammalian study review, the researchers concluded that the rigorous procedures developed for mammalian reproduction held promise for practical application in human embryonic stem cell (hESC) line production. (wikipedia.org)
  • developmental
  • A technique appropriate to investigation of the developmental fates of distinct embryonic cell types is described and the fate of a particular type of chick myoblast (CMR-I) examined. (biologists.org)
  • We also saw that the embryos that developed the furthest were from the same egg donors, suggesting that genetic variation between egg donors plays an important role in the developmental potential of cloned embryos. (bioethics.net)
  • morally
  • But beyond that, the creation and destruction of a human embryo is morally repugnant to people who believe an embryo has the same moral standing as a human being. (kwit.org)
  • viable
  • this approach has been championed as an answer to the many issues concerning embryonic stem cells (ESC) and the destruction of viable embryos for medical use, though questions remain on how homologous the two cell types truly are. (wikipedia.org)
  • Controversy surrounds human ESC work due to the destruction of viable human embryos. (wikipedia.org)
  • Furthermore, they specifically proposed hESC research should steer away from attempting to produce viable offspring, focusing efforts on the use of cloned embryos as a viable source for deriving stem cell lines instead. (wikipedia.org)
  • manipulation
  • We are now faced with the possibility of mastering the art of this manipulation to the point of being able to clone in research laboratories the cells that, in other circumstances, lead to fully developed human beings. (questia.com)
  • make
  • Actually the nice thing about this is that if you had some genetic disease(like cystic fibrosis) you could take the genetic material out of one of your skin cells, correct it, and then use that with this process to make an embryo. (slashdot.org)
  • The few clones that make it into adulthood are often plagued by bizarre health complications. (eurekalert.org)
  • They're basically charged with the ability to make any other cells and tissues, and even organs. (abc.net.au)
  • Cells from these embryos closely match the men and could, in theory, be used to make near-identical tissue, blood or organ transplants for the men. (bioethics.net)
  • If verified, it would be only the second confirmed time someone's been able to use cloning methods to make human embryonic stem cells, considered the body's master cells. (bioethics.net)
  • sperm
  • Then, after a long search, they finally found the best way to stimulate each egg so that it would develop into an embryo without the need to be fertilized with sperm. (kwit.org)
