A REPORT this week that will allow British scientists to take the first steps down the road of human cloning is likely to draw widespread protest.
The Human Fertilisation and Embryology Authority (HFEA) and the Human Genetics Advisory Commission (HGAC) have been consulting on the ethics of cloning since January. (93)
On Tuesday they published their conclusions, firmly opposing the cloning of a human child in place of the normal means of reproduction,
but leaving the door open for cloning human material for therapeutic purposes.
Scientists and ethicists have been pondering the possibilities with increased urgency ever since Dolly, the cloned sheep, was created nearly two years ago.
The HFEA/HGAC wants to anticipate what may be possible in 10 years time so that the debate will precede the technology. (94)
The report proposes leaving the door open ,but insists that scientists will have many hurdles(障碍) to cross if they seek permission to experiment in this area.
It expects to be asked to permit the cloning of an embryo of perhaps eight to 10 days growth. (95)
The procedure would be to remove a cell from the skin of a human being and fuse its nucleus into a human egg from which the nucleus has been removed.
The embryo would develop in a test tube to the point where a line of stem cells--the basic cells which have the potential to become any part of the human body, whether brain, kidney or leg--have developed. The material could then be frozen and stored for later use.
(96)
Medical opinion is in favour of proceeding with cloning in the hope of helping the sufferers of diseases such as Parkinson’s.
