Nuclear transfer from genetically engineered laboratory cells (1 janv. 1997 – 31 déc. 1997)

Description:

To create the transgenic sheep, the scientists performed nuclear transfer using donor DNA from the cultured transgenic cells. The result was Polly, a sheep that produced Factor IX protein in her milk. This experiment showed that sheep could be engineered to make therapeutic and other useful proteins in their milk, highlighting the potential medical and commercial uses for cloning.
