Abstract
Disclosed herein are the DNA sequences encoding human and bovine acidic and basic fibroblast growth factors (FGF). Expression of these sequences results in practical amounts of proteins useful in effecting wound healing.
Claims5
A method for producing basic human fibroblast growth factor (FGF), which comprises
- (i) culturing host cells harboring a recombinant DNA expression vector which comprises DNA encoding human basic fibroblast growth factor, wherein the vector expresses the DNA encoding human basic fibroblast growth factor in a microorganism or cell culture harboring said vector, the culturing being carried out under conditions permitting the expression of the DNA encoding said basic FGF;
- and
- (ii) recovering the basic FGF produced.
A method to produce basic human fibroblast growth factor which comprises
- (i) culturing a microorganism transformed with a recombinant DNA expression vector which comprises expression control sequences operably linked to a DNA encoding human basic fibroblast growth factor, said microorganism expressing the DNA encoding basic fibroblast growth factor under conditions permitting expression of the DNA encoding said basic fibroblast growth factor and
- (ii) recovering the basic fibroblast growth factor produced.
A method to produce basic human fibroblast growth factor which comprises
- (i) culturing a cell culture which expresses DNA encoding human basic fibroblast growth factor, obtained by transforming a cell line with a recombinant DNA expression vector which comprises expression control sequences operably linked to a DNA encoding human basic fibroblast growth factor, under conditions permitting expression of the DNA encoding said basic fibroblast growth factor and
- (ii) recovering the basic fibroblast growth factor produced.
