Obtaining source material for cellular agriculture.

Cellular Agriculture (CellAg) is an attractive concept for innovative technology with the intent to provide food and nutrition complementary to existing supply streams. The past decade has seen considerable progress in the field with advancement of cellular technology that delivers the initial building blocks for meaningful implementation. The availability of natural cell-based material that can serve as nutrient-filled source for human consumption at low cost is a critical challenge for the emerging cellular agriculture industry. Therefore, here the isolation of bovine myofibroblasts of the Black Angus breed has been pursued and accomplished together with its characterisation by using RNA sequencing and proteomics through western blotting. To transition CellAg from a concept to a game changing technology for the industry, multiple challenges need to be overcome. The field requires powerful initial material, i.e., dedicated cells that can proliferate and differentiate robustly at scale. The methodology described allows for the production of healthy cells, which have been unequivocally characterized as clonal representatives of a stable myofibroblast cell line using transcriptomics and proteomics validation. Stringent and rigorous live cell monitoring of a nascent cell line derived from healthy muscle tissue allowed for stable cell growth. In this research article, a simple and precise methodology is presented for creating a bovine myofibroblast cell line (). Our work puts forward a low-tech use of materials and expertise that is devoid of transgenic approaches, thus creating a reliable approach for lab-scale research.
