Methods and compositions for production of fallopian tube epithelium
The fallopian tube epithelium (FTE) has been recognized as a site of origin of high-grade serous ovarian cancer (HGSC). However, absence of relevant in vitro human models that can recapitulate tissue-specific architecture has hindered understanding of FTE transformation and initiation of HGSC. Here, induced pluripotent stem cells (iPSCs) were used to establish a novel 3-dimensional (3D) human FTE organoid in vitro model containing the relevant cell types of the human fallopian tube as well as a luminal architecture that closely reflects the organization of fallopian tissues in vivo. Modulation of Wnt and nodal/activin signaling pathways provided iPSC differentiation into Müllerian cells and subsequent use of pro-Müllerian growth factors promoted FTE precursors. The expression of Müllerian markers verified correct cellular differentiation. An innovative 3D growth platform, which enabled the FTE organoid to self-organize into a convoluted luminal structure, permitted final differentiation to a FTE lineage. This powerful human-derived FTE organoid model can be used to study the earliest stages of HGSC development and to identify novel and specific biomarkers of early fallopian tube epithelial cell transformation. |

Matrix fermentation systems and methods for producing microbe-based products
The subject invention provides methods of producing advantageous microbes and/or by-products using a modified form of solid-state fermentation, or matrix fermentation. In particular, the methods utilize foodstuff mixed with liquid nutrient medium to produce a three-dimensional scaffold substrate having ample surface area on which the microbes can grow. The methods can be used to cultivate yeasts, fungi and bacteria at high concentrations without susceptibility to total contamination. The subject invention can be used in remote locations and can be transported with ease. |

Portable bioreactor
A portable bioreactor is provided for driving displacement of at least one stirring sleeve relative to at least one tube cassette in a first direction and includes a machine frame unit and a first elevator. The first elevator includes a first linear movement module, a first transmission module, and a first turning module. The first linear movement module includes a first slider which is slidable on the first guide rail in the first direction between a first top position and a first bottom position. The first turning module is coupled to the first slider through the first transmission module so as to permit turning of the first turning module to be translated by the first transmission module into linear sliding movement of the first slider at a varying speed. |

Substrates for high-density cell growth and metabolite exchange
A polymer or other substrate optimized for growing cells is described, which takes the form of a micro-thin bag with gas permeable sides. Sides of the bag can be held at a fixed distance from one another with a multitude of tiny micropillars or other spacers extending between them, keeping the bag at a predetermined thickness and preventing the bag from collapsing and the sides from sticking together. In other embodiments, the sides may be held apart by gas pressure alone. A 0.01 μm to 1000 μm parylene or other biocompatible coating over the bag outsides controls the permeability of the bag material and provides a bio-safe area for cell growth. An alternate configuration uses open-cell foam with skins coated with a biocompatible coating. Tubes going into multiple bags can be connected to a manifold that delivers gaseous oxygen or removes carbon dioxide and other waste gases. Multiple bags can be stacked together tightly, with o-ring spacers in between, and housed within a vessel to form a high-surface area, ultra-compact cell growing system. For cells growing on the bags, liquid nutrients can be fed by way of the tube spacers, and oxygen and waste gases permeated through the bag sides and transported within the bags. |

Methods of making unit-dose products with supercooling
Disclosed is a method for producing a unit-dose capsule which includes optionally forming the first film into the shape of a first cavity, supercooling a first component to a temperature at which the equilibrium state of the first component is a solid or semi-solid, dispensing the first component in a supercooled state into the first cavity, such that the first component gels to form at least one layer of gel adhered to and/or in contact with the first film, forming a second film into the shape of a second cavity, filling the second cavity with a second component, sealing the first film to the second film to form a sealed cavity having at least one chamber containing the first component and the second component. The method may further include wetting and perforating the first film. The unit-dose capsule includes the sealed container and the two components. |
