A full-function artificial organ fitting body comprises a cortex layer and an organ body tissue area. The organ body tissue area comprises a growth area, a differentiation area, a docking area, a branch arterial system, a branch nervous system and a branch venous system. The branch arterial system, the branch nervous system and the branch venous system are distributed in the differentiation area and form a main body three-dimensional skeleton structure with the outer growth area and the middle docking area.

A method of forming a tissue or an organ, including: disposing, in a support medium in a gel state, a composition comprising a live biologic; changing a state of the support medium from the gel state to a solid state; and supporting, in the support medium at the solid state, the live biologic in the composition.

The invention generally relates to cells and compositions comprising same for use in cell therapy, to methods of obtaining same, and to use of same in cell therapy. In one aspect, the invention provides a method for forming a cell composition from a tissue sample, the method comprising: providing a tissue sample comprising cells; contacting the sample with a polymer in binding conditions, said binding conditions being conditions that enable binding of cells in the sample to the polymer, so that said cells are bound to the polymer; culturing the cells bound to the polymer under conditions and for a time that allows the cell number to increase; providing conditions to induce a phase change of the polymer; thereby forming a cell composition from a tissue sample.

The disclosure relates to the fabrication of a three dimensional [3-D] cell culture membrane comprising one or more functionalized surfaces adapted to provide cell culture conditions suitable for the analysis of proliferation, differentiation or function of cells, typically eukaryotic or prokaryotic cells.

The disclosure relates generally to a system, device, and method for cell culturing. In certain embodiments, the system, device, and method may be used to encapsulate single cells in embryo-like, core-shell microcapsules. In some embodiments, microfluidic devices may be utilized to fabricate core-shell hydrogel microcapsules, which may be used to encapsulate individual cells. In some embodiments, the disclosed system and method are utilized to encapsulate cancer stem cells. The disclosed system, device, and method can be used to isolate and culture CSCs, to facilitate the understanding of cancer biology and etiology, and to advance the development of effective CSC-targeted cancer therapies.

Described herein is a cell culture system for constructing a perfusable network of self-assembled cells comprising a multi-well plate embedded with microchannels connecting a central well with at least one inlet well and at least one outlet well, the central well for culturing seeded cells within an extracellular matrix, wherein the perfusable network allows perfusion through the microchannels connecting the central well with at least one inlet well and at least one outlet well. The cell culture system allows the array of perfusable networks formed, connected, and perfused inside the multi-well plate to be accessible and/or extractable from the top of the central well. In aspect, the cell culture system can improve the experimental throughputs of organ-on-a-chip systems and expand the application of microphysiological systems to regenerative cell therapy. A perfusable network of self-assembled cells and method of making thereof using the cell culture system described herein are also provided.

Disclosed are methods for coating microcarriers with a marrow stromal cell derived extracellular matrix, and maintaining and expanding mammalian mesenchymal stem cells on the marrow stromal cell derived extracellular matrix coated microcarriers in culture.

The present invention provides a medium composition containing deacylated gellan gum or a salt thereof, and an acidic polysaccharide or a salt thereof capable of maintaining a random coil state in a divalent metal cation medium and cross-linking via a divalent metal ion, and permitting culture of a cell or a tissue in suspension, wherein a concentration of the deacylated gellan gum or a salt thereof in the medium composition is 0.002-0.01 (w/v) %, a concentration of the acidic polysaccharide or a salt thereof is 0.004-0.1 (w/v) %, and a mass ratio of the acidic polysaccharide or a salt thereof to the deacylated gellan gum or a salt thereof is not less than 1. In addition, the present invention provides a method for isolating a cell or tissue from a culture preparation containing the medium composition and cell or tissue, including applying a shear force to the culture preparation.

The present disclosure provides a substrate for cell culture. Systems comprising the substrate, and methods for using and manufacturing the substrate are also disclosed herein.

An extrudable hydrogel composition useful for making a three-dimensional organ construct includes a cross-linkable prepolymer, a post-deposition crosslinking group, optionally, an initiator that catalyzes the reaction between the prepolymer and said the crosslinking group; live cells (e.g., plant, animal, or microbial cells), optionally at least one one growth factor, and optionally water to balance. Methods of using the same and products so made are also described.
