Abstract: Provided herein are methods to increase the culture density and/or thickness of a cellular biomass in a cultivation infrastructure, to improve the culture of cells in the absence of serum in a cultivation infrastructure, and to promote anchorage-independent growth of a cellular biomass in a cultivation infrastructure. The methods comprise inhibiting the HIPPO signaling pathway, for example, by activating YAP1, activating TAZ, and/or inhibiting MOB1, LATS1 kinase, LATS2 kinase, WW45, MST1 kinase, and/or MST2 kinase in the cellular biomass. In some embodiments, the cellular biomass is harvested from the cultivation infrastructure for the formulation of cell-based food products or ingredients, such as animal meat manufactured from cells in an ex vivo process or for therapeutic applications such as organ or tissue transplantation or grafting.

Abstract: The present disclosure relates to a substrate apparatus (and methods of manufacturing the same) with one or more substrates having a substrate spacing for growing a cell mass. In particular embodiments, the disclosed substrate apparatus includes a substrate wound into a coiled configuration with an intra-coil spacing between coil layers. To provide the intra-coil spacing, certain implementations use a separator. For example, a separator is applied to a substrate surface, and the separator-substrate combination is wound together (e.g., around a spool). In turn, a locking element is attached to the substrate to maintain the coiled configuration. The separator is then removed via heat treatment, chemical treatment, or physical displacement—thereby leaving the intra-coil spacing between the coil layers. Alternatively, no separator is used to provide a substrate spacing. For example, in lieu of a separator, the locking element is actively applied to the substrate during the winding process.

Abstract: Described herein are novel systems and methods for biomanufacturing, such as tissue cultivation. In some variations the systems and methods may comprise at least one porous substrate.

Abstract: This disclosure describes methods for growing cells in a controlled environment in a growing room, transporting the cells to a harvest room, and removing the cells from the controlled environment in the harvest room. The disclosed method can limit exposure of cells to contaminants by maintaining a controlled environment through cell growth and additional processing. For instance, the cells may be washed and cooled within the controlled environment. The cells are transferred to a harvest room where they are harvested and removed from the controlled environment.

Abstract: Provided herein are filter cake-based systems and methods for cultivating cells and cell biomass therefrom. Provided herein is a system for cultivating cells and cell biomass comprising a filter chamber comprising at least one inlet and at least one outlet, at least one filter support located within the filter chamber, and a filter cake located on the filter support, wherein the filter cake comprises at least one filter aid and a plurality of cells. Provided herein is a method for optimizing the cultivation of cells and cell biomass, comprising providing a filter support, adding at least one filter aid to the filter support, adding a plurality of cells to the filter aid, wherein the cells and the filter aid together comprise a filter cake, growing the cells into a cell biomass in the filter cake, wherein the filter cake is at least partially compressible.

Abstract: Provided herein are cell-based meat compositions suitable for consumption comprising cells harvested from suspension cell culture and comprising an emulsion mixture. Also provide here are methods of making a cell-based meat composition suitable for consumption comprising: culturing a population of cells in suspension; harvesting the population of cells to produce a cell mass; formulating an emulsion mixture by: (i) emulsifying an oil with a hydrocolloid to produce an oil:hydrocolloid mixture; and (ii) adding the cell mass to the oil:hydrocolloid mixture to form an emulsion mixture; and (d) forming the cell-based meat composition into a patty.

Abstract: Provided herein are methods relating to making non-natively occurring myogenic cells. For example, provided herein are methods for transdifferentiating a liver-derived cell to a non-natively occurring myogenic cell. In another example, the method relates to using dedifferentiation to make non-natively occurring myogenic cells.

Abstract: Provided herein are methods of engineering a cell line for reduced dependence on exogenous growth factor(s). In some embodiments, the method includes introducing into a cell one or more of: a polynucleotide comprising a coding sequence of a growth factor ligand; a polynucleotide comprising a coding sequence of a growth factor receptor; or a polynucleotide comprising a coding sequence of an activated downstream growth factor target, and culturing the cells in a cultivation infrastructure.

Abstract: The present disclosure provides methods and compositions useful for the production of slaughter-free meat products, and the characterizations of the same. The slaughter-free meat products contain several points of distinction when compared to conventional meat procured by harvesting the tissue of a dead animal. Such points of distinction include, but are not limited to, significantly reduced or substantially no: steroid hormones, antibiotics, or microbial contamination; lower fat content; no vasculature; and extended shelf life both at room temperature and when refrigerated.

Abstract: A plant fat-based scaffold for growing cell-based meat products for consumption. The scaffold comprises primarily plant fats or waxes in addition to cell binding proteins and optional additional components that assist in the growth of cultivated animal cells. The scaffold can exist in both a liquified state during sterilization and a solid state during the formation of the scaffold, the seeding of the cultivated cells, and the cellular growth phase. The scaffold is capable of remaining in the final product for consumption or is partially or completely melted out of the final product and recycled into raw material for forming new scaffolds.
