OHSU Researchers Announce New Discovery

...he gene in their nervous system, which resulted in embryos with smaller brains with neurons, but no glial cells. When the neural stem cells were isolated and placed into cell culture, and the Brg1 was removed, the cells became neurons, but did not differentiate into glia. As the Brg1 expression which is i...

Stem Cell Bank In UK Would Require 150 Embryo-Derived Stem Cell Lines

...urprisingly, a sub-set of stem cells from 10 human embryos have been identified that could theoretically provide a very good match for about 38% of recipients. Similar to human organ transplantation, the embryonic stem cells from a therapeutic bank would have to be tested for tissue compatibility to minimi...

Risk Of Birth Defects Slightly Increased Due To IVF

...efects. In the routine IVF protocol, two or more embryos are commonly transferred to a woman's uterus to increase the chances of success. This has been pointed to increase birth defects owing to the possibility of multiple pregnancy (twins, triplets) and premature delivery. More studies are clearly indic...

Sperm stem cells could be an alternative to embryonic stem cells in future

...es stemming from the source of these cells - human embryos or mouse cells. Ordinarily, when germ stem cells divide into two cells, one "daughter" cell differentiates to become a sperm while the other remains a stem cell. The study represents a remarkable breakthrough as the fate of the male germ cells that...

Embryonic Genetic Testing Is Boosting IVF Pregnancies

...such as cystic fibrosis or Down syndrome to screen embryos and implant only those that do not carry the disease-causing genes in the mother's uterus. The test can also detect any chromosomal abnormalities that may affect an embryo's chance of survival once it has been implanted in the uterus. PGD was devel...

Stem cells Can Generate Organs In Labs

... stem cells to develop a layer found in developing embryos that gives rise to the thyroid, thymus, lungs, liver, pancreas and the lining of the respiratory and digestive tracts This layer is called endoderm. "We have described an approach to produce highly enriched cultures of definitive endoderm from (huma...

Limb Regeneration In Humans: A Future Possibility

...hout scars within hours, a feat possible for human embryos until the age of about six months. Adult frogs retain the capacity and salamanders can even grow new tails and limbs when severed. According to Prof Amaya, humans most likely lose this perfect healing capacity with age, because it is important to hea...

Successful creation of human embryos from a single parent for the first time

...ful in creating so-called parthenotes, early-stage embryos that are made from a single egg, without the need for sperm. The researchers have so far created six parthenotes by taking donated eggs from women who were undergoing sterilization. The eggs were given an electric shock to make them divide. Parthen...

The ministers in the UK government want the British public to submit its views on whether couples should be able to use embryo-screening or sperm-sorting techniques to choose the sex of their u...

World’s First Nerve Stem Cells Produced

... However, critics say it is unethical to use human embryos in scientific research. Previous attempts at creating the nerve cells have produced contaminated samples that have not been scientifically useful. Robert Meadowcroft, of the Parkinson's disease Society, welcomed the news: "The purity of these cells...

SNUPPY – Woo Suk Hwang reveals World’s first dog cloe

...g a small electric shock to start development, the embryos were implanted into the uterus of a surrogate mother, which was a labrador dog. The team used DNA fingerprinting to confirm that Snuppy was genetically identical to his “father”. Successful nuclear transfer in dogs has been elusive until now because...

Langer said his lab will seek federal money to continue research using the same stem cell cultures, which were obtai...

New Stem Cells lines will be required

Cloning of human embryos for stem cells made possible

Korean scientists have been able to clone human embryos for creating stem cells that may be used to help //patients with diseases or injury. The newly created stem cell lines are an exact match with the patients’ DNA and immune systems. . This research have provided new insight into using stem cells clon...

New turn in stem cell research

... was derivation of a new stem cell line from human embryos under new conditions. The new process evolved out of research is likely to bring about changes in the way stem-cell studies are going on. The research came out in the current issue of The Lancet. Link: http://www.thelancet.com/journal/vol365/iss946...
