Abstract: Engineered, reinforced leather materials (engineered leathers) including a composite of a fibrous matrix that has been tanned to allow crosslinking of the fibrous matrix to the collagen formed by cultured cells (e.g., fibroblasts). These engineered leathers may be referred to as fiber-reinforced biological tissue composites. Also described herein are methods of making such fiber-reinforced biological tissue composites.

Abstract: The invention relates to compositions comprising (i) biocompatible hydrogel and (ii) one or more therapeutic agents contained within said hydrogel; wherein the hydrogel is cross-linked utilizing a cross-linker comprising a peptide sequence that is capable of being degraded by an enzyme; the therapeutic agent being effective as a treatment of a condition related to the presence of the enzyme.

Abstract: Edible microcarriers, including microcarrier beads, microspheres and microsponges, appropriate for use in a bioreactor to culture cells that may be used to form a comestible engineered meat product. For example, the edible microcarriers described herein may include porous microcarriers that may be used to grow cells (e.g., smooth muscle cells) and may be included with the cells in the final engineered meat product, without requiring modification or removal of the cells from the microcarriers. In a particular example, the edible microcarriers may be formed of cross-linked pectin, such as pectin-thiopropionylamide (PTP), and RGD-containing polypeptide, such as thiolated cardosin A. Methods of forming edible microcarriers, methods of using the edible microcarriers to make engineered meat, and engineered meat including the edible microcarriers are also described herein.

Abstract: Biofabricated leathers made by electrocompaction and/or electrospsinning. Described herein are biofabricated leather materials derived from electrospun or electrocompacted collagen networks. These electrospun or electrocompacted leathers may have leather-like properties following and are may be processed as native leather and used to form leather goods.

Abstract: A biofabricated material comprising a network of crosslinked collagen fibrils produced from recombinant collagen that contains substantially no 3-hydroxyproline residues is disclosed. This material is composed of collagen which is also a major component of natural leather and is produced by a process of fibrillation of collagen molecules into fibrils, crosslinking the fibrils and lubricating the crosslinked fibrils. Unlike natural leathers, this biofabricated material exhibits non-anisotropic (not directionally dependent) physical properties, for example, a sheet of biofabricated material can have substantially the same elasticity or tensile strength when stretched or stressed in different directions. Unlike natural leather, it has a uniform texture that facilitates uniform uptake of dyes and coatings. Aesthetically, it produces a uniform and consistent grain for ease of manufacturability.

Abstract: Described herein is a method for producing a biofabricated material from collagen or collagen-like proteins which are recombinantly produced and which contain substantially no 3-hydroxyproline. The collagen or collagen-like proteins are isolated from animal sources, or produced by recombinant DNA techniques or by chemical synthesis. The collagen or collagen-like proteins are fibrillated, crosslinked, dehydrated and lubricated thus forming the biofabricated material having a substantially uniform network of collagen fibrils.

Abstract: The invention is directed to a composite material comprising a biofabricated material and a secondary component. The secondary component may be a porous material, such as a sheet of paper, cellulose, or fabric that has been coated or otherwise contacted with the biofabricated material. The biofabricated material comprises a uniform network of crosslinked collagen fibrils and provides strength, elasticity and an aesthetic appearance to the composite material.
