Currently the most successful cloning technique is the same process which allowed Dolly the sheep to be cloned - [somatic cell nuclear transfer]?. It is also the technique used by ACT, the first company to succesfully clone a human embryo (see research section below). An [egg cell]? taken from a donor has its nucleus removed. Another cell with the genetic material to be cloned is fused with the original cell. |

In the November 25th 2001 issue of the Journal of Regenerative Medicine, a US company [Advanced Cell Technology]? claimed that it had successfully created a clone of a human, in the form of an embryo. ACT vice-president Dr Robert Lanza said that the company's intention was to use this in therapeutic cloning, in order to harvest embryonic stem cells from a patient. These, it is hoped, could be used to grow cloned tissue and organs for transplantation in to the patient. |

These, it is hoped, could be used to grow cloned tissue and organs for transplantation in to the patient. Some scientists objected that the ACT cloning had not actually been succesful because the cloned embryos had only divided so far, meaning it was possible that the transplanted genetic material had not actually been used. Further criticisms were of the company's inability to collect much useful information from the experiment, and of them being unable to harvest stem cells. The company stressed that it was against reproductive cloning and they hoped to develop purely theraputic processes. |

The company stressed that it was against reproductive cloning, which has supporters such as the scientists Dr [Panayiotis Zavos]?, Dr [Brigitte Boiselier]? and Dr [Severino Antinori]?. Antinori claims that a cloned baby will be possible before 2003. However the majority of scientists including [Ian Wilmut]?, who led the first team to clone [Dolly the sheep]? at the [Roslin Institute]?, claim that there are many further complications to reproductive human cloning in its current form. Aside from the ethics involved the scientists claim that it is simply too risky. In a debate for the [American National Academy of Sciences]? Wilmut quoted the low survival-rate of cloned animals as evidence that human cloning would be dangerous. The main fears are that children will be born with genetic disorders, which might develop or worsen over the years. |

An argument supporting the banning of embryonic cloning is simply that it is unnessecary - there are many theraputic treatments being investigated which would have equal benefits. However this is not an argument to ban cloning, as there is no danger in exploring new alleys of research. |
