This cross-journal collection on "Cultivated Meat and Alternative Protein Sources" is a collaboration between Nature Communications, npj Science of Food, Communications Biology and Scientific Reports. This rapidly growing field combines materials science, stem cell technology, tissue engineering and other disciplines to generate meat and alternative protein options that are more ethical and sustainable to feed the growing world population. We are keen to see submissions in this exciting space, specifically but not exclusively in the areas of Alternative or non-animal Protein Sources, Cultivated Meat Technology (including cell lines, tissue engineering, culture media) and Cultivated Meat Considerations.
Achieving organoleptic properties of conventional meat is important for cultured meat production. Here, the authors demonstrate that the texture, flavor, and nutritional content of cultured meat can be significantly enhanced by regulating cell differentiation inside hydrogel scaffolds.
Cultured meat technology promises to alleviate protein shortages, but still faces many challenges. Here, the authors achieve serum-free myogenic differentiation of porcine pre-gastrulation epiblast stem cells and generate meat-like tissue via edible plant-based scaffolds without any animal compounds.
Researchers establish an immortalized porcine preadipocyte cell strain for cell-cultured fat research and production, which can be cultured extensively. differentiated within 3D bioscaffolds to generate cell-cultured fat, and co-differentiate with muscle precursor cells, producing a pattern similar to real meat.
Cultured meat (CM) is a sustainable alternative for meat, providing similar eating experience and nutrition. Here the authors present and fully characterize a CM platform from cellularized edible microcarriers and oleogel-based fat substitute.
A marbled muscle-adipose tissue construct is developed by integrating engineered bovine muscle and adipose tissue, and optimized using alginate-based 3D constructs and short differentiation times to increase adipogenic differentiation and maturation
A substitution of FBS in culturing of bovine satellite cells for the purpose of culturing meat is presented, addressing both basal media and growth factors in relation to proliferating and differentiating cells.
