A method for producing a cell construct including, contacting Schwann cells or Schwann cell-like cells with a biocompatible matrix, and subjecting to cultivation, where the cultivation is at least partially performed by administering mechanical stimulation on the cells in contact with the biocompatible matrix. A cell construct obtained by the method.

An object of the present invention is to provide a novel approach capable of conveniently producing a large quantity of substantially uniform size cell aggregates. Provided is a method for producing cell aggregates using a cell culture bag, the cell culture bag having a lower face comprising a plurality of recesses, the method comprising the steps of: (1) adding cells and a medium to the cell culture bag, stirring the contents, and culturing the cells while applying a pressure to the cell culture bag; and (2) recovering the formed cell aggregates after the completion of culture.

Engineered skin substitutes comprising an outer-facing portion and an inner-facing portion and methods of making the same are provided. The skin substitutes are configured to conform to a shape and a dimension of a body part of a subject, and have at least one surface that circles back on itself so as to enclose at least a portion of the body part. In some instances, dermis and epidermal layers can be formed in an air liquid interface. The exemplary skin substitutes are wearable and can be made to conform to a generic body part or a specific body part from a three-dimensional representation of the body part.

Described are devices for tethering biological materials, which in applicable embodiments support the growth and differentiation thereof. In a specific embodiment, the biological materials are cells and the cells grow/differentiate into tethered three-dimensional aggregates. The devices disclosed herein may be used in various methods/assays relating to tethered biological materials, such as to tethered three-dimensional aggregates of cells.

Disclosed are methods of promoting wound healing in a patient in need thereof comprising administering to the patient a composition comprising a neonatal fibrin scaffold. Further disclosed are in vitro methods for evaluating a target composition on human wound healing comprising a neonatal porcine plasma scaffold with the target composition and evaluating scaffold properties of the plasma sample.

A method of producing a 3D tissue composite, comprising: a preparation step in which a multiple number of sheet-shaped first structures containing first cells are prepared, wherein at least one of the multiple number of first structures holds a second structure containing second cells; a stacking step in which the multiple number of first structures are stacked to form a 3D composite; and a culturing step in which the 3D composite is cultured to form a 3D tissue composite containing first tissues formed from the first cells and second tissues formed from the second cells.

Cells may be cultured by a method including the following steps: a first step of preparing a population of cell aggregates having a major axis of not more than 400 μm, and a second step of suspension culturing the population of cell aggregates obtained in the first step.

The present invention relates to a differentiation method for obtaining a large quantity of microglia by patterning, proliferating, culturing, and inducing the differentiation of yolk sac-mimic 3D organoids prepared from human pluripotent stem cells, wherein the microglia thus obtained in a large quantity exhibit significantly superior effects in terms of yield, purity, and storage stability compared to cells differentiated by existing differentiation methods, and thus may be utilized in research on lesions and therapeutic mechanisms of brain diseases, and drug screening platforms.

The present disclosure relates to improved methods serum free stem cell culture, particularly 3D culture in bioreactors as well as cell culture medium and compositions for use in the same. Such methods may be particularly suitable for large scale cell manufacture.

The invention provides a method for preparing an ordered cell-containing microarray, and a system for preparing an ordered cell-containing microarray.
