PPL develops sheep carrying human genes

PPL develops sheep carrying human genes

PPL Laboratories has developed the first cloned animal to carry human genes. A sheep called Polly will produce human proteins in her milk.

It opens up the field for producing identical flocks of sheep or other farmyard animals able to produce human proteins in their milk for treating diseases. PPL has done this by adding a human gene plus a marker gene to the genetic material or nucleus. The nucleus was then introduced into sheeps eggs from which the DNA had been removed.

The company is working with the Roslin Institute, near Edinburgh, which recently announced it had cloned Dolly the sheep. Professor Grahame Bulfield, director of the Roslin Institute, said: This pioneering work will stimulate new opportunities in both agricultural and bio-medical research.
