A bioreactor system for conditioning of pluripotent cells or cell media is provided. In further aspects, conditioned pluripotent cells and methods for making such cells are provided.

Bone marrow containers are described herein. Separation systems for separating activated immune cells from other components are described herein. Methods of activating an immune cell are described herein.

The present invention provide a medium composition for suspension culture of an adherent cell, containing (1) a chitin nanofiber; and (2) a chitosan nanofiber or a polysaccharide.

A significant interferon (IFN) response is induced following treatment of CHO cells with exogenously-added type I IFN or poly I:C. Treatment of the CHO cells with poly I:C prior to infection limited the cytopathic effect from Vesicular stomatitis virus (VSV), Encephalomyocarditis vims (EMCV), and Reovirus-3 vims (Reo) in a STAT1-dependent manner By knocking out two upstream repressors of STAT1: Gfi1 and Trim 24, the engineered CHO cells exhibited increased resistance to virus contaminations. Thus, omics-guided engineering of mammalian cell culture can be deployed to increase safety in biotherapeutic protein production.

Disclosed is a method for manufacturing a composite nanofiber support and a fish collagen/synthetic polymer nanofiber support manufactured by the method, wherein the method comprises: a first step for dissolving a synthetic polymer in an organic solvent; a second step for dissolving a fish collagen in water to prepare an aqueous fish collagen solution; a third step for adding the aqueous fish collagen solution prepared in the second step to the synthetic polymer solution prepared in the first step, followed by mixing; and a fourth step for electrospinning the mixture solution prepared in the third step to manufacture a nanofiber support.

The present application discloses a cell culture media for growth, maintenance and induction of reversion to a less mature state of a cell comprising a MUC1* activating ligand.

A method of controlling red blood cell production includes contacting red blood cell precursors with a composition including a zinc chelator, a composition including an inhibitor of a zinc importer protein, or a combination thereof; wherein the contacting inhibits survival of the red blood cell precursors, inhibits terminal differentiation of the red blood cell precursors to mature red blood cells, or a combination thereof.

The present invention is in the field of pluripotent stem cells. In particular the invention relates to a method for (closed system) induction of differentiation of pluripotent stem cells towards a pre-selected cell type, such as, for example, cardiomyocytes or endothelial cells. The method as disclosed herein is particularly useful to upscale the production of cells derived from pluripotent stem cells, in particular (human) cardiomyocytes and/or endothelial cells derived from pluripotent stem cells.

Methods are disclosed for fabricating a three-dimensional engineered blood retinal barrier (BRB) comprising a choroid and retinal pigment epithelial cells. The methods include the use of bioprinting. Also disclosed is a three-dimensional engineered BRB, and its use. Methods are also disclosed for using the three-dimensional engineered BRB, such as for the treatment of retinal degeneration in a subject or screening. A three-dimensional printing insert that is adapted for bioprinting on a culture substrate sheet that is securely retained within and exposed through a printing frame is also disclosed.

Described are decellularized human extracellular matrix (ECM) morsels for use in tissue regeneration and repair.
