Methods of inducing cardiomyocytes from induced pluripotent stem cells by contacting induced pluripotent stem cells with silica nanoparticles comprising regulators of canonical Wnt signaling and coated with a biodegradable polymer.

Provided are mesenchymal stromal cell (MSC)-derived extracellular vesicles (EV) having tethered (membrane-bound) TGF- (MSC-derived membrane-tethered TGF- EV), and compositions containing such EV for use as therapeutics and immunomodulatory agents. Provided also are diagnostic methods and methods of assessing or monitoring disease status and/or progression in patients using membrane-tethered TGF- derived from a variety of cell sources that serve as detectable, quantifiable biomarkers in biological samples. The MSC-derived membrane-tethered TGF- EV can also be used to deliver various bioactive agents to a target cell or tissue for treating various diseases. The level of TGF- tethered to the membrane of the EV can also be modified or manipulated in vitro or ex vivo. Such modified MSC-derived membrane-tethered TGF- EV are useful as immunotherapeutic agents in the treatment or management of certain diseases, particularly those involving inflammation, autoimmunity, transplant rejection and cancer.

Provided herein are seed train processes and methods of producing a recombinant protein that include the use of these seed train processes.

The invention provides a method for inducing adenohypophysis or precursor tissue thereof in vitro from human pluripotent stem cells. The method includes culturing an aggregate of human pluripotent stem cells in suspension in a medium containing a bone morphogenetic protein signal transduction pathway activating substance and a substance acting on the Shh signal pathway to obtain a human cell aggregate containing a hypothalamus neuroepithelial tissue and a surface ectoderm, and further culturing the obtained human cell aggregate containing the hypothalamus neuroepithelial tissue and the surface ectoderm in suspension in a medium containing a bone morphogenetic protein signal transduction pathway activating substance and a substance acting on the Shh signal pathway to induce formation of hypophysial placode and/or Rathke's pouch in the surface ectoderm, thus obtaining a human cell aggregate containing 1) hypothalamus neuroepithelial tissue, and 2) hypophysial placode and/or Rathke's pouch.

Cell cultures comprising poly(oxazoline) stabilizers and use of poly-(oxazolines for stabilizing cell cultures

Described are cell cultures containing in a cell culture medium one or more water-soluble poly(oxazolines).

The water-soluble poly(oxazoline) acts as a stabilizer for the cells and reduces the mechanical stress exerted by agitating the cell culture medium on the cells. This leads to an improved survival rate of the cells compared to the unstabilized state.

The present application discloses cell clusters resembling the function and characteristics of endogenous pancreatic islets, and methods for making and using such cell clusters.

Provided herein are, inter alia, compositions, systems, kits, and methods for culturing and expanding cells (such as T cells, diploid or non-diploid cells), as well as methods for treating disorders (e.g., with T cells), and methods for producing biological molecules and compositions (e.g., proteins, viruses, viral particles or fragments thereof, etc.), including vaccines.

Provided herein are methods and culture systems for production of a biologically active Wnt polypeptide under a minimal serum condition. Also described herein include methods and culture systems for production of a biologically active Wnt polypeptide in a serum-free condition.

The present invention relates to the field of in vitro 3D modeling of neural tissues, particularly of the brain. There is the need of developing cell culture models of neural tissue that reflect physiological aspects of neural tissue. The present invention provides methods of producing bioengineered neuronal organoids (BENOs) which form functional neuronal networks. The present invention also relates to uses and applications of the produced BENOs, e.g., in the fields of drug screening and personalized medicine.
