The invention relates to molecular biology, biotechnology, medicine, veterinary science. A group of inventions is proposed: a fusion protein comprising a ligand to MATN1 protein, and a growth factor of EGF, TGF, FGF, IGF, the construct components are connected via a flexible link, characterized by the amino acid sequence of FIG. 1； such fusion protein further comprising the Fc-fragment of an antibody or a polypeptide binding with FcRn and/or transferrin or a fragment thereof, the construct components connected via a flexible link, characterized by the amino acid sequence of FIG. 1； encoding polynucleotide, codon-optimized for expression in the producer cells or a target organism, a genetic construct for the synthesis of the fusion protein in producer cells, or cells of a target organism, the fusion protein producer, a producer of a genetic construct based on a bacterial cell, a preparation for the regeneration of cartilage containing at least 1 fusion protein or genetic construct as the active agent, in an effective amount, and a physiologically acceptable carrier or buffer solution, for parenteral or, in the case of the preparation based on at least 1 fusion protein containing the transport domain, oral administration, in the latter case the preparation is enclosed in an enteric coating, all variants
