The invention relates to a method and composition for the cultivation, expansion and production of extracellular vesicles, and the preservation and/or pre-treatment of cells, wherein said composition is a medium or media supplement or a solution comprising pterostilbene or the derivatives thereof, and/or a migration inhibitory factor antagonist and optionally a bivalent cation.

The present disclosure relates to novel multi-organ-chips establishing the differentiation of induced pluripotent stem cell (iPSC)-derived cells into organ equivalents on microfluidic devices and corresponding methods of generating organ equivalents. The present disclosure also relates to novel bioengineered tissue constructs mimicking organ barriers generated with iPSC-derived endothelial cells and/or organoids bioprinted in, and/or seeded on, a hydrogel. The present disclosure further relates to methods of bio-engineering organ constructs comprising co-culturing iPSC-derived organ precursor cells and iPSC-derived fibroblasts and endothelial cells. The present disclosure specifically provides a microfluidic device comprising: (i) iPSC-derived hepatocyte precursor cells; (ii) iPSC-derived intestinal precursor cells; (iii) iPSC-derived renal tubular precursor cells; and (iv) iPSC-derived neuronal precursor cells; wherein the iPSC-derived precursor cells according to (i), (ii), (iii) and (iv) are differentiated from a single donor iPSC reprogrammed from a single type of somatic cell.

An immortalized sweat gland myoepithelial cell which expresses -SMA and pan-cytokeratin and has a sphere forming ability after subculture at least 5 times. A method for producing immortalized sweat gland myoepithelial said method comprising: while culturing a cell structure, wherein sweat gland myoepithelial cells are exposed on a surface, in a state of being suspended in a medium, transferring an immortalizing gene into the cells; and then culturing the transgenic structure thus obtained in a state of being suspended in the medium to thereby obtain immortalized sweat gland myoepithelial cells.

The present invention is directed to the use of microfluidics in the preparation of cells and compositions for therapeutic uses.

The present disclosure provides a fabrication process that results in creating large arrays of living cells, such as stem cells, which are subsequently exposed to nanoliter quantities of compounds to test the efficacy on cellular metabolism.

An organ-on-a-chip microfluidic device is disclosed that mimics a human lymph node and/or human lymphoid tissue. The device can include cells from human blood and lymphatic tissue, include an extracellular matrix for the development of immune system components, and provide for the perfusion of fluids and solids resembling blood and lymphatic fluid within micrometer sized channels.

Described herein are a system, device, methods and compositions related to generating 3-dimensional cardiac tissues. Also described herein are a system, device, and methods of maturing 3-dimensional cardiac tissues and maintaining their viability in culture.

Provided herein are materials and methods for the preparation of blood products. In one aspect, provided herein is a composition including platelets or platelet derivatives and an aqueous medium, wherein the aqueous medium has a protein concentration less than 50% of the protein concentration of donor apheresis plasma.

Aspects of the present disclosure include methods that include co-culturing a cell and a microparticle that includes a capture ligand, in a culture medium under conditions in which a biomarker produced by the cell is bound by the capture ligand. Such methods may further include detecting (e.g., by flow or mass cytometry) complexes that include the microparticle, the capture ligand, the biomarker, and a detection reagent. The methods may further include determining the proportion or number of cells among a heterogeneous cell population that produced the biomarker and/or the level of biomarker secreted by such cells. Compositions, systems and kits are also provided.

The present invention provides hollow microcarriers for cell culture. The hollow microcarriers form a shell around a hollow interior and can be opened to permit cell infiltration or harvesting. The hollow microcarriers protect cells from hydrodynamic shear stress without hindering the diffusion of nutrients in and out of their hollow interior.
