The blastocyst stage is developed by the egg to help create embryonic stem cells from the inner cell mass of the blastocyst. (wikipedia.org)
A blastocyst (cloned or not), because it lacks any trace of a nervous system, has no capacity for suffering or conscious experience in any form - the special properties that, in our view, spell the difference between biological tissue and a human life worthy of respect and rights. (wikiquote.org)
Stem cells were then derived from the inner cell mass of the blastocyst. (scienceblog.com)
The Korean researchers who performed this stem cell research improved upon their protocols that yielded the first embryonic stem cell line from a cloned human blastocyst. (scienceblog.com)

The first being a female gamete, known as the ovum (egg/oocyte). (wikipedia.org)
Each of the 11 new human embryonic stem cell lines was created by transferring the nuclear genetic material from a non-reproductive cell of a patient into a donated egg, or "oocyte," whose nucleus had been removed. (scienceblog.com)
Oocyte donors and patients who donated non-reproductive cells were all unpaid volunteers. (scienceblog.com)

Scientists from the Monash Institute of Medical Research (MIMR) and colleagues from New South Wales will compare two different methods of creating patient-specific stem cells: somatic cell nuclear transfer (SCNT) and induced pluripotent stem cells (iPS). (medicalxpress.com)
Unlike SCNT, iPS cells are derived from adult cells, such as skin, which are reprogrammed to behave like embryonic stem cells. (medicalxpress.com)
Once our team produces the iPS cells, we will compare the properties of iPS versus cells developed through SCNT. (medicalxpress.com)
Australia is already a global leader in overall stem cell research and this new and clear regulatory framework gives us an opportunity to extend our leadership into SCNT which could transform how we treat diabetes, heart diseases and Parkinson's," Mr Jennings said. (medicalxpress.com)
In human SCNT experiments, these eggs are obtained through consenting donors, utilizing ovarian stimulation. (wikipedia.org)
For example, if a person with Parkinson's disease donated their somatic cells, the stem cells resulting from SCNT would have genes that contribute to Parkinson's disease. (wikipedia.org)
Another application of SCNT stem cell research is using the patient specific stem cell lines to generate tissues or even organs for transplant into the specific patient. (wikipedia.org)
Only a handful of the labs in the world are currently using SCNT techniques in human stem cell research. (wikipedia.org)
Once the SCNT is done, the cloning is over. (nationalrighttolifenews.org)
The cloning is completed when the SCNT is accomplished. (nationalrighttolifenews.org)

Successful somatic-cell nuclear transfer (SCNT) depends on the quality, availability and maturation of the animal's unfertilized oocytes. (nature.com)
Indeed, if passed, Hatch/Feinstein/Kerry would explicitly legalize doing in humans the very cloning procedure -- somatic cell nuclear transfer (SCNT) -- that was used to make Dolly the sheep . (lifeissues.net)
Comment: Indeed, if passed, "total cloning bans" H.R. 534, H.R. 234, H.R. 916, and S. 245 would not ban anything either - not even the SCNT cloning technique that was used to make Dolly the sheep. (lifeissues.net)
The technique used by Drs. Mitalipov, Paula Amato, M.D. , and their colleagues in OHSU's Division of Reproductive Endocrinology and Infertility, Department of Obstetrics & Gynecology, is a variation of a commonly used method called somatic cell nuclear transfer, or SCNT. (ohsu.edu)
The promise of the SCNT method is that the nucleus of a patient's skin cell, for example, could be used to create pluripotent cells that might be able to repair a part of that patient's body. (pharmaceuticalintelligence.com)
One attraction of SCNT has always been that the genetic identity of the new pluripotent cell would be the same as the patient's, since the transplanted nucleus carries the patient's DNA. (pharmaceuticalintelligence.com)
Stanford University have raised the possibility in the past that the immune system of a patient who received SCNT-derived cells might still react against the cells' mitochondria, which act as the energy factories for the cell and have their own DNA. (pharmaceuticalintelligence.com)
This reaction could occur because cells created through SCNT contain mitochondria from the egg donor and not from the patient, and therefore could still look like foreign tissue to the recipient's immune system. (pharmaceuticalintelligence.com)
When transplanted back into the nucleus donor strain, the cells were rejected although there were only two single nucleotide substitutions in the mitochondrial DNA of these SCNT-derived cells compared to that of the nucleus donor. (pharmaceuticalintelligence.com)
When scientists at the Oregon Health and Science University announced success in performing SCNT with human cells last year, it reignited interest in eventually using the technique for human therapies. (pharmaceuticalintelligence.com)
Although many stem cell researchers are focused on a different method of creating pluripotent stem cells, called induced pluripotent stem cells, there may be some applications for which SCNT-derived pluripotent cells are better suited. (pharmaceuticalintelligence.com)
The immunological reactions reported in the new paper will be a consideration if clinicians ever use SCNT-derived stem cells in human therapy, but such reactions should not prevent their use. (pharmaceuticalintelligence.com)
This research informs the medical community of the margin of safety that would be required if, in the distant future, researchers need to use SCNT to create pluripotent cells to treat someone. (pharmaceuticalintelligence.com)

Cloning entails taking the nucleus - the compartment that contains the DNA - from an adult cell and putting it into an egg from which the original nucleus has been removed. (nih.gov)

It involves transplanting the nucleus of one cell, containing an individual's DNA, into an egg cell that has had its genetic material removed. (ohsu.edu)
Furthermore, because these reprogrammed cells can be generated with nuclear genetic material from a patient, there is no concern of transplant rejection," explained Dr. Mitalipov. (ohsu.edu)

After the somatic cell transfers, the cytoplasmic factors affect the nucleus to become a zygote. (wikipedia.org)

A potential use of stem cells genetically matched to a patient would be to create cell lines that have genes linked to a patient's particular disease. (wikipedia.org)
Two separate research teams have figured out how to "reprogram" cells with just a handful of genes to give them the characteristics of embryonic stem cells. (nih.gov)
The fact that the DNA of a fully differentiated (adult) cell could be stimulated to revert to a condition comparable to that of a newly fertilized egg and to repeat the process of embryonic development demonstrates that all the genes in differentiated cells retain their functional capacity, although only a few are active.
