TRANSGENICALLY PRODUCED PLATELET DERIVED GROWTH FACTOR

摘要

The invention features transgenically produced PDGF, e.g., transgenically produced PDGF which is expressed in the milk of a transgenic mammal, and is present in the milk in active form, e.g., as a dimer. The invention also features methods of producing transgenic PDGF, transgenic animals capable of expressing PDGF, and nucleic acid sequences encoding PDGF, e.g., nucleic acid sequences encoding PDGF, under the control of a mammary gland specific promoter.
