Abstract
A method for producing a recombinant mammal in vivo is disclosed. The mammal has a mammary gland, with mammary epithelial cells lining a duct in that gland One increases the rate of mitosis of the mammary epithelial cells (e.g. by using perphenazine or a mitogen), and one then exposes the mammary epithelial cells in vivo in the gland to a recombinant vector (e.g. a retrovirus vector). The mammary epithelial cells can be pretreated (or simultaneously treated) with polybrene to facilitate infection by virus vectors, and the vector can have a signal sequence which causes foreign proteinaceous material to be secreted into the milk produced by the mammary gland. Also disclosed are recombinant non-human mammals produced by such methods and novel milk products that they produce.
