Fiber-based biomaterial scaffolds for cell support towards the production of cultivated meat.

The in vitro production of animal-derived foods via cellular agriculture is emerging as a key solution to global food security challenges. Here, the potential for fiber-based scaffolds, including silk and cotton, in the cultivation of muscle cells for tissue formation was pursued. Mechanical properties and cytocompatibility with the mouse myoblast cell line C2C12 and immortalized bovine muscle satellite cells (iBSCs) were assessed, as well as pre-digestion options for the materials due to their resilience within the human digestive track.

Cultivated Meat from Aligned Muscle Layers and Adipose Layers Formed from Glutenin Films.

Cultivated meat production is a promising technology to generate meat while reducing the reliance on traditional animal farming. Biomaterial scaffolds are critical components in cultivated meat production, enabling cell adhesion, proliferation, differentiation, and orientation. In the present work, naturally derived glutenin was fabricated into films with and without surface patterning and in the absence of toxic cross-linking or stabilizing agents for cell culture related to cultivated meat goals.

Edible films for cultivated meat production.

Biomaterial scaffolds are critical components in cultivated meat production for enabling cell adhesion, proliferation, differentiation and orientation. Currently, there is limited information on the fabrication of edible/biodegradable scaffolds for cultivated meat applications. In the present work, several abundant, naturally derived biomaterials (gelatin, soy, glutenin, zein, cellulose, alginate, konjac, chitosan) were fabricated into films without toxic cross-linking or stabilizing agents.

Assessment of asymmetrical dimethylarginine metabolism in patients with critical illness.

Background: Critically ill patients experience metabolic disorders including hypercatabolic state and hyperglycaemia, and these are associated with poor outcome. Hyperglycaemia and asymmetrical dimethylarginine (ADMA) are reported to have significant influences on endothelial dysfunction. The aim of this study was to examine the relationship between plasma ADMA and related arginine metabolism in patients with critical illness.
