Two teams of doctors in China are to administer embryonic stem cell therapy from fertilised human embryos to treat different degenerative diseases... [Read More]

Healthy mice created from eggs and sperm without conventional fertilisation

19 September 2016 - by Paul Waldron

Unfertilised mouse egg cells that have been made to divide can develop into healthy offspring by the injection of sperm, according to a new study... [Read More]

Event Review: Pint of Science Festival - From Sticky Sperm to Sugary Doughnuts

26 May 2015 - by Natalie Moska

Last week I attended a Pint of Science session entitled 'Sugar and Sperm' held at a floating pub on Albert Embankment in London - part of a worldwide festival hosting more than 600 evenings of science in 50 cities and eight countries as far afield as Australia and the USA... [Read More]

Advocate General paves the way for 'stem cell patents'

21 July 2014 - by Antony Blackburn-Starza

An advisor to the Court of Justice of the European Union (CJEU) has said that certain stem cells derived from unfertilised human eggs that have undergone parthenogenesis should not be excluded from patentability.... [Read More]

Patenting parthenotes: High Court asks if parthenotes are 'human embryos' under the Biotech Directive

29 April 2013 - by Antony Blackburn-Starza

The UK's High Court has asked the Court of Justice of the European Union (CJEU) to clarify if human parthenotes fall under the definition of a human embryo for the purposes of patentability... [Read More]

Unexpected breakthrough revealed from Hwang cloning scandal

06 August 2007 - by Antony Blackburn-Starza

The disgraced South Korean stem cell scientist, Woo Suk Hwang, whose spectacular fall from grace dominated the newspaper headlines early last year, has been credited with 'accidentally' creating the world's fisrt stem cells produced from an unfertilised human egg. An international collaboration of scientists last week published... [Read More]

Rodent cells could boost human ES cell research

04 July 2007 - by MacKenna Roberts

Two separate teams have successfully isolated a new type of rodent stem cell that closely resembles human embryonic stem (hES) cells. The Oxford and Cambridge University studies, both published in the journal Nature, show that this new stem cell type could help shed light on human ES... [Read More]

Mouse stem cells from single egg

18 December 2006 - by Heidi Nicholl

Researchers at the Children's Hospital Boston, have developed a technique in mice to derive stem cells from a single egg coaxed to divide. The technique of forcing an egg cell to begin division without fertilisation by a sperm cell - known as parthenogenesis - has been achieved before, but... [Read More]

South Korean team faked all human stem cell work

12 January 2006 - by BioNews

The panel investigating the work of South Korean scientist Woo Suk Hwang has reported that further research published by his team was faked. The scientists, based at Seoul National University (SNU), claimed in 2004 that they had created the world's first embryonic stem (ES) cell line from a cloned human... [Read More]

Frozen-thawed ovary transplant success in sheep

15 September 2005 - by BioNews

Israeli scientists have obtained early sheep embryos after transplanting whole ovaries that had been frozen and thawed. The researchers, based at the Institute of Animal Science, Agriculture Research Organisation, Bet Dagan, report that the ovaries were still working normally three years after the transplant. They say their findings, published in... [Read More]

UK's first 'parthenotes' created

10 September 2005 - by BioNews

A team of scientists from the Roslin Institute in Edinburgh, Scotland, has created the UK's first parthenogenic embryos, or 'parthenotes'. Using parthenogenesis - a Greek word that means 'virgin birth' - the research team were able to create embryos without the need for fertilisation of an egg by sperm. The Roslin team... [Read More]

US stem cell and cloning legislation news

04 July 2005 - by BioNews

Supporters of a US bill to extend federal funding of research on human embryonic stem (ES) cells are predicting a victory when it is debated by Senators later this month. More than 60 are expected to vote in favour of the legislation, say its proponents - although President Bush has pledged... [Read More]

Human stem cell lines derived from unfertilised eggs

02 July 2005 - by Heidi Nicholl

Scientists working in Italy have reported success in deriving human stem cell lines from eggs stimulated to divide without sperm. Embryos created from the process of parthenogenesis are known as parthenotes, and never normally develop beyond a few days. The team, from the University of Milan, developed... [Read More]

US stem cell state legislation news

20 June 2005 - by BioNews

The Delaware Senate has approved a bill (called SB 80) that would prohibit human cloning for reproductive purposes but allow cloning for research purposes. Senators approved the bill, sponsored by State Senator Robert Venables, by 14-7 last Tuesday. The bill will allow human embryonic stem (ES) cell research to... [Read More]

When is an embryo not an embryo?

06 December 2004 - by Dr Kirsty Horsey

Recent news reports have highlighted the fact that scientists are searching for a way to create human embryonic stem (ES) cells without destroying human embryos. Normally, the derivation of ES cells requires that the embryo they came from be destroyed in the process. Many people have no ethical problem with... [Read More]

Eggs 'tricked' into becoming embryos

02 December 2004 - by BioNews

A method for persuading human eggs to start dividing as though they have been fertilised could provide a less controversial source of embryonic stem (ES) cells, say UK researchers. The scientists, based at the University of Wales in Cardiff, also say that the technique might help improve the success rate... [Read More]

Cloning creates abnormalities, ICSI doesn't, report finds

02 July 2004 - by BioNews

American researchers have revealed that cloning causes abnormalities in resulting embryos, but they found no evidence of defects in those created by other assisted reproduction techniques. The researchers were trying to investigate concerns that assisted reproductive technologies increase the risk of the rare genetic disorders Beckwith-Wiedemann and Angelman syndromes. Drs...

Do parthenogenetic mice spell the end of men?

26 April 2004 - by Dr Jess Buxton

Does the birth of the world's first 'parthenogenetic' mouse, created using eggs from two female mice, really mean that men will soon be redundant? Well, no - if anything, it confirms that for mammals, sexual reproduction is the only way to make babies, thanks to a phenomenon known as imprinting. Last... [Read More]

Fatherless mice born

23 April 2004 - by BioNews

A mouse 'conceived' from the egg cells of two female parents, with no input from a male sperm cell, has grown into a normal, healthy adult. The Japanese scientists who created the mouse - called Kaguya - believe that this is the first time a mammal has been created in this way... [Read More]

Wilmut confirms human cloning application

23 April 2004 - by BioNews

Professor Ian Wilmut, leader of the team that created Dolly the sheep, is applying for the UK's first licence to clone human embryos for stem cell research, saying it would be 'immoral' not to carry out such research. Cloning human embryos for medical research purposes - a procedure known as therapeutic... [Read More]
