Growth factors-infused cellulose scaffolds support cost-efficient proliferation and differentiation of bovine stem cells for cultivated meat

ABSTRACT: Cultivated meat, which aims to replicate traditional meat using tissue engineering and stem cell biology, is a promising approach to sustainably supplementing traditional meat production to meet increasing global demand. The production of structured cultivated whole-cut-like meat constructs is not trivial; it requires a complex structure that supports cell growth, enables nutrient and waste exchange, and mimics natural texture. Here, we develop a biocompatible, porose, and anisotropic scaffold, based on directional freezing of nano and microcrystalline cellulose, which supports the growth and differentiation of bovine mesenchymal stem cells toward fat and muscle lineages. Furthermore, we show that preloading the scaffolds with growth factors directing the cells for proliferation or differentiation is a promising alternative to conventional media delivery since these pretreated scaffolds yield similar proliferation and differentiation efficiencies using at least 10 times lower masses of prohibitively expensive factors, and thus may significantly lower one of the primary boundaries to price parity with traditional meat. Together, these findings propose a strategy that supports the development of structured, muscle-like cultivated constructs and represents a step toward whole-cut meat as a sustainable and ethically preferable alternative to meet the growing demand for a widely studied target product.

Enhanced Media Optimize Bovine Myogenesis in 2D and 3D Models for Cultivated Meat Applications [in vivo scRNA-Seq]

Project description:Livestock farming and conventional meat production pose significant environmental, health, and animal welfare challenges. In seeking sustainable alternative solutions, cultivated meat technology typically utilizes differentiation of myogenic progenitor cells (MPCs) into muscle cells for in vitro meat production. However, understanding the molecular determinants governing MPC differentiation into muscle cells, and the potential enhancement of this process through modulation of signaling pathways, remains limited. Herein, we characterized the molecular landscape associated with bovine MPC differentiation in vitro by employing multiomics, and explored its augmentation by small molecules, together leading to identification of media that enhanced myogenic differentiation compared with conventional methods in both 2D cultures and tissue‐engineered 3D skeletal muscle constructs. Through bulk and single‐cell transcriptomics and proteomics, we compared conventional and enhanced differentiation media, demonstrating that the enhanced media gave rise to unique progenitor‐like cell populations, while simultaneously promoting differentiation into myocytes and contractile myotubes expressing a wide array of myogenic markers that more closely resemble bovine muscle cells in vivo. The improved method for promoting myogenic differentiation in 2D and 3D formats, together with the corresponding molecular roadmap, may prove valuable for cultivated meat applications.

Simplifying adipogenic differentiation – a step towards a food compatible media

Project description:Cultivated meat is a promising technology with the potential to mitigate the ethical and environmental problems associated with traditional meat. Fat plays a key role in meat flavour and texture, however little academic research has focused on fat production resulting in a paucity of adequate adipogenesis protocols for most livestock-derived cells. The development of a suitable protocol is essential to pave the way for cultivated fat as an ingredient, as the traditional cocktail of IBMX, dexamethasone, insulin and rosiglitazone is not food-compatible. Here, we investigate the necessity of these four classic adipogenesis inducers in a serum-containing and an in-house developed serum-free medium (DMAD). Using a full-factorial design, we show that only two of these four inducers, insulin and rosiglitazone, are necessary for adipogenic differentiation, as measured by gene expression changes and lipid accumulation. Additionally, two glucocorticoid receptor binding molecules, progesterone and hydrocortisone, found in DMAD and FBS, are also required. Importantly, this protocol also leads to mature adipocytes in 3D, edible hydrogels. This was demonstrated in both media types and in four species; ruminant and monogastric. We therefore propose this as an alternative protocol for adipogenesis, which, given the replacement of rosiglitazone by a food-compatible PPARγ agonist, can be suitable for human consumption.

GM-free immortalization and high yield production of cultured chicken [WGS]

Project description:Global demand for animal protein is expected to double by 2050 at a time when resource-intensive livestock production is reaching peak capacity. Cellular agriculture offers an opportunity to meet the increasing demand for animal products, but the technology is currently limited by the genetic stability of immortalized cells, low culture yields, and high production costs. Here we demonstrate the spontaneous immortalization and long-term genetic stability of fibroblasts derived from the indigenous Israeli Baladi and the commercial Broiler Ross chicken breeds. Cells were adapted for growth as single-cell suspensions in animal-component free culture medium reaching cell densities of over 100x10^6 cells/mL in ATF perfusion presenting a production yield of over 33% w/v. We show that soy phosphatidylcholine, a major component of lecithin, activates PPAR, driving adipogenesis in immortalized chicken fibroblasts. Harvesting cultured adipocytes and blending them with high moisture extruded soy protein formed cultured chicken strips in which mouth feel and texture were supported by a blend of animal and plant proteins while aroma and flavor were driven by cultured animal fat. Visual and sensory analysis graded the product 4.5 out of 5.0, with over 85% percent of the study group said they are extremely likely to replace their food choice with this cultured meat product. The ability to create immortalized lines without genetic modification and the high yield process for cultured meat production presents an important steppingstone in the market realization of cultured meat.

CRISPR-mediated engineering of bovine satellite cells for AGS-compatible cultivated meat

Project description:Alpha-gal Syndrome (AGS) is a potentially life-threatening allergy caused by an IgE-mediated immune response to galactose-α-1,3-galactose (alpha-gal), a carbohydrate epitope present in most mammalian meats. Currently, strict avoidance of mammalian meat remains the primary management strategy for affected individuals, and alpha-gal–free beef is not commercially available. Here, we leverage cultivated meat as a biotechnology platform to address this unmet clinical need by engineering alpha-gal–free bovine muscle cells. Using CRISPR/Cas9 genome editing, we disrupted GGTA1, the gene encoding α1,3-galactosyltransferase, in immortalized bovine satellite cells. High-efficiency editing produced clonal GGTA1 knockout cell lines harboring a homozygous frameshift mutation. Flow cytometry and immunofluorescence confirmed loss of the alpha-gal epitope, while bulk RNA-seq indicated minimal disruption of global gene expression and preserved myogenic differentiation capacity. Importantly, lysates from GGTA1 knockout cells elicited substantially reduced basophil activation in assays using plasma from a patient with AGS, indicating reduced basophil activation consistent with reduced allergenic potential. Together, these findings establish a proof of concept for engineering AGS-compatible cultivated meat and demonstrate the potential of cultivated meat technologies to address human health challenges.

Optimisation of cell fate decisions for cultured muscle differentiation

Project description:Production of cultured meat requires defined medium formulations for the robust differentiation of myogenic cells into mature skeletal muscle fibres in vitro. Whilst such formulations can drive myogenic differentiation to an extent similar to serum-starvation based protocols, these cultures are visually heterogeneous in nature, with a significant proportion of cells not participating in myofusion, limiting the maturation of the muscle. Here, we use RNA sequencing to characterise this heterogeneity at single-nucleus resolution, identifying distinct cellular subpopulations, including proliferative cells that fail to exit the cell cycle, and 'reserve cells' that do not commit to myogenic differentiation. By targeting the ERK, RXR and NOTCH pathways, we show that cell cycle exit can be promoted whilst simultaneously abrogating reserve cell formation. Under these improved culture conditions, fusion indices close to 100% can be robustly obtained in 2D culture. We further show that this translates to higher levels of myotube formation and muscle protein accumulation in animal-free bioartificial muscle (BAM) constructs, providing proof of principle for the generation of highly differentiated cultured muscle with excellent mimicry to traditional meat.

Muscle-derived fibro-adipogenic progenitor cells for production of cultured bovine adipose tissue

Project description:Cultured meat is an emergent technology with the potential for significant environmental and animal welfare benefits. Accurate mimicry of traditional meat requires fat tissue; a key contributor to both the flavour and texture of meat. Here, we show that fibro-adipogenic progenitor cells (FAPs) are present in bovine muscle, and are transcriptionally and immunophenotypically distinct from satellite cells. These two cell types can be purified from a single muscle sample using a simple fluorescence-activated cell sorting (FACS) strategy. FAPs demonstrate high levels of adipogenic potential, as measured by gene expression changes and lipid accumulation, and can be proliferated for a large number of population doublings, demonstrating their suitability for a scalable cultured meat production process. Crucially, FAPs reach a mature level of adipogenic differentiation in three-dimensional, edible hydrogels. The resultant tissue accurately mimics traditional beef fat in terms of lipid profile and taste, and FAPs thus represent a promising candidate cell type for the production of cultured fat.
