    摘要: The present invention relates to the production of large quantities of a novel chimeric TGF-.beta., termed TGF-.beta.1/.beta.2, by eucaryotic host cells transfected with recombinant DNA vectors containing the TGF-.beta.1/.beta.2 precursor coding sequence controlled by expression regulatory elements. Simian TGF-.beta.1 cDNA (Sharples et al., 1987, DNA 6:239-244) was modified so that the nucleotides encoding amino acid residue numbers 9-13, 17, 19, 25 and 26 of the mature TGF-.beta.1 sequence were hanged to the nucleotides encoding the corresponding amino acids of the mature TGF-.beta.2 structure. Simian codon usage was maintained. The chimeric TGF-.beta.1/.beta.2 of the invention induces effects on the proliferation of vascular endothelial cells equivalent to those induced by TGF-.beta.1.

    摘要: cDNA clones coding for TGF-.beta.2 which are used to construct expression vectors capable of directing the high-level expression of mature, biologically active TGF-.beta.2, as well as precursor TGF-.beta.2 forms, in transfected Chinese Hamster Ovary cells (CHO cells) and transfected COS cells are described. CHO and COS transfectants secreting TGF-.beta.2 at high levels are also described. CHO cells transfected with a plasmid vector carrying the complete 414 amino acid simian TGF-.beta.2 precursor secrete approximately 5 .mu.g per ml culture media.
