But it is remarkable that the Church has pronounced that there has been insufficient scientific study without first asking the scientists who lead this research, the families who stand to benefit, or the Wellcome Trust, which funds it, to explain the science to the Archbishops Council. The Church appears to have ignored the unprecedented independent scrutiny of scientific, ethical and public opinion about mitochondrial donation conducted over the last seven years. Next Tuesday, MPs will vote to amend the Human Fertilisation and Embryology Act 2008 and legalise mitochondrial DNA transfer. The procedure, which was developed by British scientists, allows IVF clinics to replace an egg's defective mitochondrial DNA with healthy DNA from a female donor, to prevent children suffering debilitating conditions like muscular dystrophy. It is controversial because it would result in babies having DNA from three people and effectively, two mothers. Until now the Anglican Church has withheld judgement on the issue, asking for more scientific evidence. But this week it announced that it could not support the legislation. But the Rev Dr Brendan McCarthy, the Church of Englands national adviser on medical ethics, said: A wide number of questions remain to be answered before it would be wise … Continue reading →

The Church of England has said it would be 'irresponsible' to introduce laws to allow 'three parent babies' in the UK, ahead of a parliamentary vote on the issue next week. On Tuesday MPs are due to vote on whether to change the Human Fertlisation and Embryology Act 2008 and legalise mitochondial replacement therapy. According to the Telegraph, the Church of England announced yesterday that it could not support the legislation. Under the proposed legislation, IVF clinics would be able to replace defective mitochondrial DNA from an egg with healthy DNA given by a donor. This would reduce the number of children born with serious inherited diseases such as muscular dystrophy, but would also mean those children would technically have two mothers, or three parents in all. The Church has expressed concerns that the vote will happen ahead of peer-reviewed safety checks into the technology. The Church of England's national adviser on medical ethics, Rev Dr Brendan McCarthy, told the Telegraph: "The Archbishops Council, which monitors this issue, does not feel that there has been sufficient scientific study or informed consultation into the ethics, safety and efficacy of mitochondria transfer. "Without a clearer picture of the role mitochondria play in … Continue reading →

THE first "three-parent" baby in Britain could be born as early as next year following a study that scientists hope will convince the fertility regulator that the controversial IVF technique is safe, The Independent understands. Parliament is set to vote next Tuesday on regulations to make mitochondrial transfer legal. Scientists at Newcastle University intend to apply for a licence in October when the new law comes into effect, despite opposition from church groups and anti-abortion organisations. The opponents have expressed concerns over the ethics and safety of the technique, which combines the genetic material of three people into one embryo and involves the creation and destruction of fertilised eggs to treat IVF embryos. Other scientists have called for further research and have implicitly questioned the decision of the Human Fertilisation and Embryology Authority (HFEA) to ditch its previous insistence on the need for further experiments on monkeys before it issues the first IVF licence. "As well as analysing foetal development in a non-human primate model, it is essential to analyse offspring to determine that no abnormalities appear at least during early life," said Professor Justin St John, a geneticist at Monash University in Australia. However, Professor Doug Turnbull, director of … Continue reading →

This article is about the embryonic cloaca in placental mammals. For other uses, see Cloaca. The cloaca is a structure in the development of the urinary and reproductive organs. The hind-gut is at first prolonged backward into the body-stalk as the tube of the allantois; but, with the growth and flexure of the tail-end of the embryo, the body-stalk, with its contained allantoic tube, is carried forward to the ventral aspect of the body, and consequently a bend is formed at the junction of the hind-gut and allantois. This bend becomes dilated into a pouch, which constitutes the endodermal cloaca; into its dorsal part the hind-gut opens, and from its ventral part the allantois passes forward. At a later stage the Wolffian duct and Mllerian duct open into its ventral portion. The cloaca is, for a time, shut off from the anterior by a membrane, the cloacal membrane, formed by the apposition of the ectoderm and endoderm, and reaching, at first, as far forward as the future umbilicus. Behind the umbilicus, however, the mesoderm subsequently extends to form the lower part of the abdominal wall and pubic symphysis. By the growth of the surrounding tissues the cloacal membrane comes to … Continue reading →
