Iranian cloned sheep in good health

Iran and Middle East's first cloned sheep "Royana" is at good health 
conditions on 70th day of its birth, it was announced on Monday.

Born on October 1st, 2006, using cloning technology on fundamental 
cells, the Iranian cloned sheep weighs 40 kilograms and its physical and 
physiological conditions are quite satisfactory, according to it 
biologist care takers.

Successful birth of Royana thanks to tireless efforts of Rouyan 
Biological Research Center (RBRC) was a great scientific achievement for 
Iran, as the first country in the Middle East to achieve the cloning 
technology.

Research work in cloning field was launched in the year 2004 in Tehran 
and Isfahan simultaneously, focusing on cloning of sheep.

Finding the appropriate zygote and then the ovule into which the deal 
zygote was to be implanted was the first phases of the advanced 
biological project.

It was agreed finally to take advantage of the cells gained from the 
fibro-blast tissues of a sheep's earlobes for the purpose.

The study was pursued using the outside-womb-impregnation (IVF) 
technology in two phases of the sheep's cloning.

As a result of the IVF impregnation, that was tried for the first time 
in Iran, the first cloned sheep was born on October 1st 2006 in a 
caesarean operation in Isfahan.

The technique had never before been used in traditional artificial 
impregnation, that is used in animal husbandry.

The resulted embryos, inclusive of two to three sheep, were then 
transferred to the host sheep's womb, and the final result was the birth 
of a twin pair of sheep, one of whom died soon after birth.

In cloning phase of this study 230 cloned embryos were implanted in the 
womb of 77 host sheep, a twin was born alive as the result, each 
weighing around three kilograms.

The first of those twins died five minutes after birth due to problems 
it had suffered during its host's pregnancy, and the second, "Royana" is 
at good health at 70th day of its historic life now.
