European patent on stem cells may be a possibility

As long as the research meets the usual requirements for a patent, isolated embryonic stem cells should be considered for both method and product patents.

Bush adopts the so-called moral high ground and chooses to ignore scientific advice

The American President George W. Bush has used his presidential veto for the first time to block further federal taxpayers money from being used for embryonic stem-cell research.

World-first stem cell research may help male infertility

Scientists have shown for the first time that sperm grown from embryonic stem cells can be used to produce offspring.

New technique for freezing and preserving genetically enhanced pig embryos

Researchers led by a University of Missouri-Columbia professor of reproductive biotechnology have reported success in freezing and preserving swine embryos that were created by in vitro techniques and that carried modified genetic material.

Cloned stem cells are perfectly normal

Scientists generally agree that all cloned animals are biologically flawed. But they don't agree about what that means for stem cells derived from cloned embryos, the basis for therapeutic cloning.

Early embryos with abnormal chromosomes are capable of returning to normal when grown in culture in the laboratory

While such embryos are not capable of developing into normal foetuses if implanted in a woman's womb, the discovery has important implications for stem cell production, especially in countries where the creation of embryos for stem cell research is discouraged or even banned.

New way of obtaining embryonic stem cells that avoids contamination by other types of cells

Scientists in the USA have discovered a new way of obtaining embryonic stem cells that avoids contamination by other types of cells and reduces the numbers of embryos needed to create embryonic stem cell lines.

Major step forward in stem cell research

Newcastle University (England) scientists have taken a major step forward in stem cell research, putting Britain in the vanguard of technology that could produce treatments for a range of conditions such as diabetes, Parkinson’s disease and spinal injuries.

Researchers generate patient-specific stem cells

Researchers have isolated the first human embryonic stem cell lines specifically tailored to match the nuclear DNA of patients, both males and females of various ages, suffering from disease or spinal cord injury.

Guidelines for research involving human embryonic stem cells

The National Academies today recommended guidelines for research involving human embryonic stem cells, and urged all institutions conducting such research to establish oversight committees to ensure that the new guidelines will be followed.

IVF process may lack natural growth factors in fluid

The lack of natural growth factors in the fluid in which IVF embryos are grown could have lifelong effects on people conceived this way. That is the implication of a study on mice by Australian researchers, who say preliminary studies of human embryos back their claims.

Marijuana use may increase the risk of ectopic (tubal) pregnancies

It is not known whether drugs that block or, in the case of marijuana, over-stimulate the CB1 receptor can cause ectopic pregnancy in humans. However, "our results raise caution for women of reproductive ages regarding the chronic use of marijuana for recreation or pain alleviation," the researchers concluded.

Successfully cloning mice from an advanced melanoma cell

Nature can reset the clock in certain types of cancer and reverse many of the elements responsible for causing malignancy, reports a research team led by Whitehead Institute Member Rudolf Jaenisch, in collaboration with Lynda Chin from Dana Farber Cancer Institute.

Abnormalities observed in cloned mice help reinforce the need to continue to avoid the reproductive cloning of humans

Dr. Takumi Takeuchi, from Cornell University, New York, USA told a media briefing that he and Dr. Gianpiero Palermo's team had compared imprinting abnormalities (the process where specific genes inherited from both parents are silent) in mice embryos derived from assisted reproduction techniques and from cloning.

Chromosomal chaos in early embryonic development is linked to abnormalities in cytokinesis and spindle formation

Abnormalities in the spindles (the bi-polar thread like structures that link and pull the chromosomes during cell division) of human embryos before implantation may be the primary reason for many of the chromosome defects observed in early human development

Gene chip technology can detect one of the commonest cystic fibrosis (CF) genetic mutations with 100% accuracy

A single genetic test that is capable of detecting all mutations involved in the development of cystic fibrosis could be just a few years away, the 20th annual conference of the European Society of Human Reproduction and Embryology heard today (Monday 28 June).
