Novel nucleic acids, polypeptide sequences, and nucleic acid regulators thereof, have been identified which code for a fibroblast growth factor (FGF), preferably FGF-20 or FGF-23, a class of polypeptides involved in development, differentiation, and morphogenesis, e.g., in cell-cell signalling and cell proliferation. An FGF of the present invention, fragments thereof, and derivatives thereof, have one or more of the following biological activities, e.g., promoting wound healing; promoting neuronal survival; stimulating cell proliferation, e.g., proliferation of stem cells, fibroblasts, neurons, glia, oligodendrocytes, Schwann cells, or progenitors thereof; modulating differentiation of cells; inducing embryonic development; stimulating neurite outgrowth; enhancing recovery from nerve or neuronal damage; stimulating myelination; stimulating angiogenesis; receptor binding activity; modulating tumorigenesis, etc.

L'invention porte sur de nouveaux acides nucléiques, sur des séquences polypeptidiques et sur leurs régulateurs qui ont été identifiés avec un code associé à un facteur de croissance du fibroblaste (FGF), de préférence FGF-20 ou FGF-23, sur une classe de polypeptide impliquée dans son développement, dans la différenciation et la morphogenèse, notamment la signalisation cellule-cellule et la prolifération cellulaire. Un FGF, les fragments et ses dérivés bénéficient d'une ou plusieurs activités biologiques suivantes: la stimulation de la cicatrisation de blessures; la stimulation de la survie cérébrale; la stimulation de la prolifération cellulaire, dont la prolifération de cellules souches, de fibroblastes, de neurones, de névroglies, d'oligodendrocytes, de cellules Schwann ou de leurs progéniteurs; la modulation de la différenciation des cellules, la stimulation du développement de l'embryon, la stimulation de l'excroissance des neurites; un rétablissement facilité après des lésions nerveuses ou cérébrales; la stimulation de la myélinisation; la stimulation de l'angiogenèse; l'amélioration de l'activité de liaison des récepteurs et la modulation de la tumorigenèse.
