A method for meat production by in vitro cell culture includes isolating tissue from an animal or plant source and making a cell suspension of cells, and growing the cells into a solid or semi-solid structure that mimics an animal organ by growing the cells on a food-grade scaffold in a culture medium. Culture medium comprising growth factor of (i) genetically same or similar species to the cells and/or (ii) genetically same genus to the cells is used. Expression of one or more proteins in the growing cells may be increased by altering a level of one or more micro RNAs that regulate expression of the protein. Additionally, the growing cells may be co-cultured with bioengineered cells that secrete growth factors and cytokines that support the growth of the cells in situ. The co-culturing technique reduces or eliminates the need for animal-derived fetal bovine serum in the culture medium.L'invention concerne un procédé de production de viande par culture cellulaire in vitro, comprenant l'isolement d'un tissu d'une source animale ou végétale et la fabrication d'une suspension cellulaire de cellules, et la croissance des cellules dans une structure solide ou semi-solide qui imite un organe animal par culture des cellules sur un échafaudage de qualité alimentaire dans un milieu de culture.
