The paper studies how to engineer high-lipid Wagyu-like bovine fat for cultivated meat by optimizing scaffolds, fatty acid delivery, and culture conditions to improve lipid accumulation and sensory properties. Using 1% alginate as an edible scaffold and oleic acid complexed with edible albumins—especially whey protein—researchers achieved strong adipogenic differentiation and tunable rheology, with oleic acid comprising up to 80.6% of total fatty acids. Fatty acid profiling showed a bovine-like omega-6–dominated signature plus detectable omega-3 subtypes (including trace EPA and DHA), and the authors report robust adipogenesis even under lower serum conditions as a key caveat/constraint tested. This paper does not explicitly discuss endometriosis or adenomyosis; it was included in the corpus via a keyword match in the upstream search index.
Abstract
ABSTRACT Cultivated meat holds promise as a sustainable and ethical alternative to conventional meat, but reproducing the rich flavor, texture, and lipid composition of premium beef, such as Wagyu, remains a major hurdle. In this study, we redefine bovine adipogenesis by systematically optimizing edible biomaterials, fatty acid delivery systems, and culture conditions to engineer high-fat cultivated tissues with authentic sensory properties. Among various candidates, 1% alginate emerged as the optimal scaffold, providing mechanical softness compatible with adipogenic differentiation and mimicking the rheological properties of native fat. Supplementation with oleic acid complexed to edible albumins, especially whey protein (WP), significantly enhanced lipid accumulation and monounsaturated fatty acid content, particularly oleic acid, which reached up to 80.6% of total fatty acids. Engineered fat tissues displayed soft, spreadable textures and organoleptic characteristics consistent with high-quality beef fat. Fatty acid profiling revealed a bovine-like omega-6 signature, dominated by linoleic, arachidonic, and dihomo-γ-linolenic acids, alongside detectable omega-3 subtypes including alpha-linolenic acid and trace levels of EPA and DHA. This composition not only validates the physiological relevance of the engineered fat, but also highlights its potential to deliver bioactive lipids rarely found in terrestrial animal products. Additionally, the WP-oleic acid system supported robust adipogenesis even under lower serum conditions. These findings establish a food-grade, tunable platform for producing physiologically and nutritionally enhanced fat tissues, advancing the realism, functionality, and health potential of next-generation cultivated meat.
