The invention concerns the use of a recombinant nucleotide sequence containing a cDNA coding for one or several mammal collagen chains or derived proteins and elements enabling a plant cell to produce the collagen chain(s) or derived proteins, coded by said cDNA, particularly a transcription promoter and terminator identified by the transcription machinery of the plant cells, for transforming the plant cells so as to obtain from these cells, or plants obtained from them, the collagen chain(s) or derived proteins. |
