Described herein are methods, compositions, and kits for directed differentiation of human pluripotent stem cells, neuromesodermal progenitors, and neural stem cells into bioengineered elliptical neuroepithelial tissues and bioengineered neuroepithelial tubes that contain a single rosette of polarized neuroepithelial cells and have microscale cellular organization similar to that of an in vivo developing human neural tube.

Disclosed herein are devices for encapsulating biological cells and are suitable to be implanted into a subject. In different aspects of the disclosure, the devices may comprise a plurality of polymer layers. In one aspect, a device comprises a first polymer layer and a second polymer layer. In some cases, the first polymer layer may be a nanoporous polymer layer. In some cases, the second polymer layer may be a macroporous polymer layer. The first and second polymer layers may define a lumen for enclosing a population of cells. The devices may be used to transplant cells producing therapeutic agents into a subject (e.g., for the treatment of a disease).

The present disclosure relates to a nanofiber structure for cell culture, a method for manufacturing the structure, and a cell analysis device including the nanofiber structure for cell culture. The structure includes a cell culture layer made of nanofibers; and a spacer protruding upward from a surface of the cell culture layer, wherein the spacer divides a region on the cell culture layer into at least two culturing regions, wherein the spacer is made of the same nanofibers as the cell culture layer and thus has a cell migration channel defined therein.

An artificial antigen presenting cell system comprising one or more gelated human dendritic cells and a controlled release system capable of releasing one or more cytokines. Also provided herein are methods for producing the gelated human dendritic cells and uses of the artificial antigen presenting cell system for activating immune cells.

Devices, and methods for preventing immune rejections are disclosed, in which trophoblasts or trophoblast-like cells are used to induce tolerance toward allogeneic cell and tissue grafts. The devices can be used as artificial placenta vaccines to avoid immunosuppression in organ transplantation.

A reinforced biocompatible scaffold facilitates integration of biological tissue. The reinforced scaffold comprises a porous biocompatible scaffold and an arrangement of at least one biocompatible filament embedded within and fixed to the biocompatible scaffold, and/or at least one biocompatible conduit embedded within and fixed to the biocompatible scaffold.

To provide a cell culture scaffold material capable of enhancing adhesiveness of cells. The cell culture scaffold material according to the present invention contains a peptide-conjugated acrylic resin, in which the peptide-conjugated acrylic resin has a first structural part having no peptide portion in a side chain and a second structural part having a peptide portion in a side chain, and solubility parameter calculated by Okitsu's equation for the first structural part is 9.7 (cal/cm.sup.3).sup.1/2 or more and 10.7 (cal/cm.sup.3).sup.1/2 or less.

Disclosed are microbeads for cell culture and a method of monitoring cell culture using the same. More particularly, each of the microbeads for cell culture according to an embodiment of the present invention include a core and a surface modification layer formed on a surface of the core. By using the method of monitoring cell culture with the microbeads for cell culture according to an embodiment of the present invention, cell culture may be carried out in highly scaled-up dimension and easily monitored.

Compositions and methods are provided for rapid and efficient production of antibodies in vitro as well as in vivo, which may be used to neutralize antigens. More specifically, the present invention relates to scaffolds comprised of amphiphilic multiblock copolymers that can form micelles based on nonionic or amphiphilic core blocks as well as ionic blocks, and with an antigen and methods of crosslinking B cell receptors to specifically produce antibodies against the antigen in vitro as well as in vivo in a more efficient method than other available monoclonal antibody production method.

An aqueous cell culture medium composition includes an aqueous cell culture solution configured to support the culture of mammalian cells. The composition further includes a synthetic polymer conjugated to a polypeptide dissolved in the aqueous cell culture solution. The synthetic polymer conjugated to a polypeptide is configured to attach to the surface of a cell culture article under cell culture conditions. Incubation of the aqueous cell culture medium composition on a cell culture surface under cell culture conditions results is attachment to the surface of the synthetic polymer conjugated to the polypeptide.
