The present disclosure relates to tissue supports for use with engineered tissues and organoids, such as cardiac organoid chambers. In an embodiment of the present disclosure, the tissue supports are provided with a fluid-impermeable resilient member that is resiliently deformable during testing by cultured tissues formed on the surface of the tissue support.

A method of culturing human induced pluripotent stem cells includes inoculating human induced pluripotent stem cells in a culture medium at an inoculation density of 1.0×10.sup.4 to 1.0×10.sup.6 cells/cm.sup.2 in a culture vessel and subjecting the human induced pluripotent stem cells to two-dimensional culturing. A method of producing cerebral organoids includes culturing a culture of the human induced pluripotent stem cells obtained by the method of culturing human induced pluripotent stem cells in a culture medium containing a BMP inhibitor and a transforming growth factor β (TGFβ) inhibitor to form cell aggregates, culturing the cell aggregates in a culture medium containing a Wnt signal transduction pathway potentiator and an extracellular matrix, and subjecting the culturing obtained in the culturing the cell aggregates to spinner culturing.

The present invention provides a device for adipose tissue processing, microfragmentation and facilitation of mechanical separation of adipose derived stem cells (“ADSCs”), methods of using the device to generate a stromal vascular fraction (“SVF”) and methods of the SVF.

A mesenchymal stem cell harvesting system and method for increasing the efficiency of collecting and processing physiological fluids containing mesenchymal stem cells from a cavity within a patient's skeletal system. Microenvironments risk in MSC production and concentration within a cavity, for example the patient's ilium, are penetrated with a pointed instrument used to create an aperture in the hard cortical bone forming the cavity followed by the insertion of an aspiration device which extracts one or more samples of cancellous bone, bone marrow, bone marrow blood and other aspirated material. The aspirate is rinsed and may be filtered to remove unwanted material and to increase the concentration and purity of the mesenchymal stem cells in the aspirant far beyond levels formerly obtainable for use in autologous treatment of the patient.

A fluidic system for producing extracellular vesicles from suspended producer cells, including at least one container, a liquid medium contained in the container, suspended producer cells, a liquid medium agitator, a device for controlling the speed of the agitator suitable for the growth of the suspended producer cells, wherein the device for controlling the speed of the agitator, the agitator and the shape and dimensions of the container are suitable for generating a turbulent flow of the liquid medium in the container for exerting shear stresses on the producer cells in order to carry out the production of extracellular vesicles, the Kolmogorov length of the flow being less than or equal to 50 μm.

Described herein are systems and methods relating to cellular micro-masonry. Systems and methods as described herein allow a user to create three-dimensional (3D) structures of cells disposed in a 3D culture medium. Systems and methods as described herein provide for the manipulation and construction of cellular structures on a single, cell-by-cell, basis.

The present invention relates to a preparation method of a composition for culturing pancreatic organoids, a composition thereby, and an organoid culture method using the same. The present invention is capable of creating an environment that is more similar to an actual tissue than a conventional Matrigel-based culture system, and in particular, exhibits an effect of facilitating tissue differentiation in pancreatic organoid culture and effectively developing into a form that is similar to an actual tissue.

Provided herein are methods and systems for bio-printing of three-dimensional organs and organoids. Also provided herein are bio-printed three-dimensional organs and organoids for use in the generation and/or the assessment of immunological products and/or immune responses. Also provided herein are methods and system for bio-printing three-dimensional matrices.

The present disclosure concerns use of activated or inactivated fibroblasts or fibroblast-derived materials, such as exosomes from fibroblasts, for wound care. The methods and compositions are useful for purpose of tissue differentiation, cell recruitment, differentiation of local stem cells, and expansion of local cells, such as keratocytes, vasal epithelial cells, myofibroblasts, and/or dermal fibroblasts, including for initiating and/or maintaining wound healing.

A method for producing a cell sheet, the method including subjecting animal cells dispersed in a culture medium to a suspension culture while gathering the animal cells toward the center of the culture medium, to form a cell sheet floating in the culture medium.
