Cloned frog without head

England develops into the Mecca of the Biotechnologists. After Ian Wilmut from the Scottish Roslin Institute in the summer of 1996 announced the birth of a sheep grown out of a differentiated nucleus, which came under the name Dolly (1125) to world-famous and sparked a heated debate (2117), is now Jonathan Slack, developmental biology The Bath University teaches, the cloning of a frog embryo succeeded, which has no head, like the Sunday Times (www.The-Times.CO.UK /) in a report of 19.19.97 reported.

Jonathan Slack said he "relatively easy" Connetting the manipulation of genes of headless tadpoles. He can also produce those without hull and tail. After British law, the headless business can not be maintained more than a week alive, as they are not yet considered animals until this time. Since froschen and people had the same genes similar functions, this technique could also be applied to human embryos: "Instead of growing a complete embryo," he said the Times, "could be reprogrammed the embryo to, apart from the desired parts and a heart and blood circulation, to improve the growth of all other corporal parts."

This is now the idea for discussion, to cloning a living spare parts warehouse for people, but many legal and ethical boundaries will love to handle, because an embryo, which is missing from the outset the brain and the central nervous system, hardly can be defined as an embryo. Such could be produced from cells of people by cloning organs, which could possibly transplant without difficulty, because they are identical to the genome of the receiver.

The story of cloning, who culminated with the sheep Dolly, started in 1952 with fros. Two American scientists succeeded for the first time to introduce an isolated cell core into the egg of a frog at very early frog embryos and thus make clones. Jonathan Slack has been working with fros as he describes his work for a long time in order to explore the mechanisms of the early development of embryos and to identify the essential growth factors and influence. He wants to understand how a simple egg can form a highly structured organism, but he also believes that the results from the animal models can be transferred to humans, as the molecular basis of morphological development in all vertebrates are pretty similar.
