Provided are engineered meat products formed as a plurality of at least partially fused layers, wherein each layer comprises at least partially fused multicellular bodies comprising non-human myocytes and wherein the engineered meat is comestible. Also provided are multicellular bodies comprising a plurality of non-human myocytes that are adhered and/or cohered to one another; wherein the multicellular bodies are arranged adjacently on a nutrient-permeable support substrate and maintained in culture to allow the multicellular bodies to at least partially fuse to form a substantially planar layer for use in formation of engineered meat. Further described herein are methods of forming engineered meat utilizing said layers.

Disclosed herein are methods and compositions for stimulating angiogenesis, using cells descended from marrow adherent stromal cells that have been transfected with sequences encoding a Notch intracellular domain. Applications of these methods and compositions include treatment of ischemic disorders such as stroke.

This disclosure is in the field of cancer immunotherapy and relates to all cancer types, including but not limited to cancers of the breast, lung, prostate, pancreas, colon, bladder, brain, head-neck, kidney, esophagus, skin, and blood cells. The embodiments provide methods for selecting and amplifying specific targeting molecules to use in therapy and diagnostic testing. Targets include but are not necessarily limited to architecturally preserved, usually heterogeneous specific surface structures present on individual cancer cells and cancer stem cells but not on non-malignant cells. The embodiments are novel in that they provide these binding molecules for one individual's cancer regardless of the rarity of an individual cancer cell or stem cell and promptly enough to initiate treatment without requiring lengthy immunization or hybridoma production that are current art.

Methods are disclosed for forming tissue engineered, tubular gut-sphincter complexes from intestinal circular smooth muscle cells, sphincteric smooth muscle cells and enteric neural progenitor cells. The intestinal smooth muscle cells and neural progenitor cells can be seeded on a mold with a surface texture that induces longitudinal alignment of the intestinal smooth muscle cells and co-cultured until an innervated aligned smooth muscle sheet is obtained. The innervated smooth muscle sheet can then be wrapped around a tubular scaffold to form an intestinal tissue construct. Additionally, the sphincteric smooth muscle cells and additional enteric neural progenitor cells can be mixed in a biocompatiable gel solution, and the gel and admixed cells applied to a mold having a central post such that the sphinteric smooth muscle and neural progenitor cells can be cultured to form an innervated sphincter construct around the mold post. This innervated sphincter construct can also be transferred to the tubular scaffold such that the intestinal tissue construct and sphincter construct contact each other, and the resulting combined sphincter and intestinal tissue constructs can be further cultured about the scaffold until a unified tubular gut-sphincter complex is obtained.

The present disclosure provides methods of bioengineering sphincters having autologous smooth muscle cells isolated from human internal anal sphincter and autologous enteric neurospheres (neural progenitor cells) isolated from human small intestine (jejunum). The isolated neural progenitor cells and smooth muscle cells are co -cultured using dual layered hydrogels and allowed to form circular, intrinsically innervated internal anal sphincter constructs. Such innervated internal anal sphincter constructs, bioengineered internal anal sphincter constructs are useful as additive implants in the treatment of fecal incontinence.

The presently disclosed subject matter provides systems and methods for producing a three-dimensional model of a human cervix. A microdevice is provided for culturing human cervical cells. The microdevice can include an upper microchannel including live ectocervical epithelial cells. The microdevice can include a lower microchannel including a first parallel lane and a second parallel lane including stromal media. The first and the second parallel lanes can be lined with live vascular endothelial cells. The lower microchannel can include a third parallel lane including uterine fibroblasts and live smooth muscle cells embedded in hydrogel. The first, second, and third lanes of the lower microchannel can be separated by protrusion structures. The third parallel lane can be positioned in the lower microchannel in between the first and the second parallel lanes. The microdevice can further include a porous membrane positioned in between the upper microchannel and the lower microchannel.

[Object] Provided is a method of producing a nerve fascicle including efficiently extending axons of neural cells.

[Solution] Neural cells are cultivated in the presence of feeder cells including at least one type of cells selected from the group consisting of vascular component cells, perivascular cells, and oligodendrocytes.

Devices, systems, and techniques are described for printing pre-aligned microtissues into larger tissue constructs. For example, a method of printing a tissue construct includes aligning cells in a first direction to create pre-aligned microtissues, suspending the pre-aligned microtissues in a liquid to create a bioink, and depositing the pre-aligned microtissues in a second direction to create the tissue construct.
