Embryos from people and cows maintain life for three days

The University of Newcastle in England has been the first in the world to create crossbreeds between humans and cows. This achievement was received by the medical community, but the protesters called it 'crime'.

A group of scientists have created hybrid embryos after injecting human DNA into eggs taken from the ovaries of cows, which have been largely removed from genetic material.

Embryos persist for three days and are intended to provide infinite stem cells for treatments of conditions such as Alzheimer's, Parkinson's and spinal cord injuries. This ability will overcome the shortage of embryos worldwide.

Dr. Teija Peura, director of human embryonic stem cell labs at the Australian Stem Cell Center, said somatic cell nuclear transfer (SCNT) was made between species, but embryos '. 99% of people ' have pushed research to a new level.

'If successful, they will be an important additional research tool to realize stem cell therapies that treat human diseases. All ways of conducting research, including SCNT . need to be encouraged if we want to fulfill the promise of stem cell technology. '

But a colleague of Dr. Peura, Dr. Andrew Laslett, recommends that this process is not enough to provide stem cells and so it is currently only theoretical.

In January, the Embryology and Fertilization Authority licensed Newcastle University to carry out this work, but the British Parliament will debate the long-term future of similar projects next month.
Under license rules, embryos will not be allowed to develop over 14 days.

Preliminary findings on the embryo program were presented in Israel last week, and Professor John Burn, head of the University of Newcastle's Institute of Human Genetics, said they would assess more deeply before the whole expenditure. Details published.

"If the team can create living cells in the culture environment, this will open the door to deeper knowledge of disease progression without using precious human eggs. Cells using animal eggs cannot be used to treat patients for safety reasons, but they will help us get closer to the point when stem cell therapy is used. '

The Catholic Church in the United Kingdom has called this success 'crime' . Fr Kevin McGovern, Director of the Health Ethics Center Caroline Chisholm, also supports this view.

"A nearly-human-like embryo is created and then destroyed. I don't see human respect or the value of life in this work. Humanity - or even near-human embryos - no What they are creating is life, no one knows exactly what the embryos will grow in. If this is accepted in the UK, the pressure is on. this licensing has flared up again, and we are going into the prospect of almost anything allowed. "

This is not the first time hybrid embryos have been created.

This method was pioneered by the research group of Dr. Hui Zhen Sheng, Shanghai II Medical University, China. She combined human cells with rabbit egg cells to create early-stage embryos, which later form human stem cells.
