Abstract: The DNA sequences encoding human and bovine acidic and basic fibroblast growth factors (FGF) can be recombinantly expressed to obtain practical amounts of proteins useful in effecting wound healing and related tissue repair.

Abstract: There are disclosed neurotrophic factors which are capable of being expressed as polypeptides lacking the microheterogeneity associated with a related native-sequence factor, CNTF. Also disclosed are DNA sequences encoding the neurotrophic factors and methods for expressing and recovering the factors as homogeneous polypeptides.

Abstract: Human insulin analogs are disclosed. These analogs are tissue-selective. Accordingly, pharmaceutical formulations containing the analogs of the invention provide superior clinical benefits as compared to human insulin when used in the treatment of patients suffering from diabetes. The analogs are modified at amino residue A12, A15 or A19, are different from the naturally occurring residue at said position, and are hepatoselective. Also disclosed are human insulin analogs modified at amino acid residues A12 or A14 or amino acid residues A10 and A13 different from naturally occurring residues or residues at said position or positions and are peripheral selective. DNA sequences and microorganisms comprising sequences coding for human insulin analogs are also provided. Processes for preparing the human insulin analogs are described.
