Culturing of organized 3D networks of neuronal cells is provided. Individual neuronal cells are encapsulated in gel beads. The gel beads are self-assembled into ordered structures in a bioreactor. Subsequent culturing of the cells in the bioreactor leads to the formation of an organized 3D network of the neuronal cells. Such structures have many applications, especially for as says of neuronal network function and/or structure.

A composition or matrix comprising a bacteriophage and nanofibrillar cellulose or a derivative thereof in a wet or dry state is disclosed.

The present invention relates to a method for producing a fibrosis-encapsulated tumoroid (FET), and the use of the fibrosis-encapsulated tumoroid. According to the present invention, an analogue that is close to real solid cancer tissue is produced using induced pluripotent stem cell-derived cell. The analogue has significant improvement over conventional tumoroids, which fail to perfectly reflect the characteristics of human solid cancer and have a very high probability of failure in the clinical validation stage. Thus, the present invention is expected to be widely used in the fields of new anticancer drug development and precision medicine.

The present disclosure relates to implantable constructs designed to deliver antigenic therapeutic reagents to a subject while providing protection from host immune responses. In certain aspects, the constructs are designed to degrade over time or upon a particular signal, thereby providing control of the length of time the therapeutic agent is delivered to the subject.

Embodiments described herein relate generally to a three-dimensional ex vivo skeletal muscle tissue comprising a hydrogel and a plurality of cells that includes skeletal muscle cells, at least a portion of the cells being encapsulated inside the hydrogel. In some embodiments, the skeletal muscle tissue is characterized by one or more contractions in response to an electrical and/or chemical stimulation.

The present invention relates to a method of co-incubating multiple cells. According to the present invention, an interaction between the multiple cells is facilitated without causing cytotoxicity, and a single cell can be separated without damage to the cells. Therefore, the present invention can be applied to a study of regeneration on various types of tissue cells.

A method for microencapsulation includes isolating myofibroblasts from Wharton's jelly of a human umbilical cord. The myofibroblasts are microencapsulated using ultra-purified sodium alginate, wherein the myofibroblasts encapsulated in the sodium alginate form a three-dimensional spherical structure.

Various embodiments disclosed relate to conductive graphene matrix-encapsulated cells. A matrix-encapsulated cell includes an encapsulating polymer matrix including a biopolymer and graphene. The matrix-encapsulated cell also includes one or more of the cells encapsulated within the encapsulating polymer, wherein the graphene directly contacts at least some of the cells. The matrix encapsulating the one or more cells is electrically conductive.

A method for micro-tissue encapsulation of cells includes coating a tissue scaffold stamp with an extracellular matrix compound; depositing the tissue scaffold stamp onto a thermoresponsive substrate; seeding the tissue scaffold stamp with a cell culture; incubating the cell culture on the tissue scaffold stamp at a temperature that is specified, wherein the cell culture forms a cell patch that is attached to the extracellular matrix compound; removing the thermoresponsive substrate by lowering the temperature; removing the tissue scaffold stamp from the cell patch to form a micro-tissue structure by dissolving the tissue scaffold stamp in a solvent; folding the micro-tissue structure by suspending the micro-tissue in the solvent to enable the cell patch to fold the micro-tissue structure; collecting the folded micro-tissue structure from the solvent; and administering the folded micro-tissue structure to an organism.

Sub-millimeter scale three-dimensional (3D) structures are disclosed with customizable chemical properties and/or functionality. The 3D structures are referred to as drop-carrier particles. The drop-carrier particles allow the selective association of one solution (i.e., a dispersed phased) with an interior portion of each of the drop-carrier particles, while a second non-miscible solution (i.e., a continuous phase) associates with an exterior portion of each of the drop-carrier particles due to the specific chemical and/or physical properties of the interior and exterior regions of the drop-carrier particles. The combined drop-carrier particle with the dispersed phase contained therein is referred to as a particle-drop. The selective association results in compartmentalization of the dispersed phase solution into sub-microliter-sized volumes contained in the drop-carrier particles. The compartmentalized volumes can be used for single-molecule assays as well as single-cell, and other single-entity assays.
