The present invention discloses, in one embodiment, a method of using human induced pluripotent stem cells to generate three-dimensional human organ tissue for therapeutic drug toxicity and discovery⋅. In one embodiment, a high throughput microtiter plate is loaded with both wild type and Rett disease 3D spheroids and exposed to a drug library, and activity is measured and analyzed for disease rescue to wild type cell behavior.

The present application provides a pluripotent stem cell-derived neuronal culture system for use in modeling neurodegenerative diseases, drug screening and target discovery; and methods of generating homogenous, terminally differentiated neuronal culture from pluripotent stem cells, and compositions resulting thereof; as well as automated cell culture systems that sustain long-term differentiation, maturation and/or growth of neuronal cells for use in modeling neurodegenerative diseases.

In order to develop tools and methods useful in a variety of applications, including the research and development of medical treatments which involve the modification of collagen protein and use of the same, the present invention provides a modified collagen protein expressed in a transformed cell and capable of forming collagen fibers outside of the cell, wherein the transformation is performed by introducing, into the cell, polynucleotides coding the modified collagen protein.

Provide are a primay cell culture medium that contains an MST1/2 kinase inhibitor and is used for culturing laryngeal cancer epithelial cells, and a culture method using the primary cell culture medium. In the culture method, the primay cell culture medium is used to culture primary cells on a clulture vessel plated with irradiated trophoblasts, so that the primay cells proliferate rapidly. A cell model obtained by the primary cell culture medium and the primay cell culture method can be used for the efficacy evaluation and screening of drugs.

Micro-Organosphers, including Patient-Derived Micro-Organospheres (PMOSs), apparatuses and methods of making them, and apparatuses and methods of using them. Also described herein are methods and systems for screening a patient using these Patient-Derived Micro-Organospheres, including personalized therapies.

The invention provides a method for constructing a hepatic progenitor cell-like cell bank, including successively performing following processes to human primary hepatocyte cultures from different donor sources: transformation-culture, cryopreservation treatment, proliferation-culture, a first subculture treatment, virus infection, a second subculture treatment, continuous selection-culture and continuous subculture. In the method for constructing a heterogenous immortal hepatic progenitor cell-like cell bank of the present invention, the human primary hepatocyte culture of each of the donor sources is transformation-cultured before the proliferation-culture, which is beneficial in endowing the human primary hepatocyte cultures with good proliferation performance. Once combined with subsequent controlling of culture parameter, the immortal hepatic progenitor cell-like cell lines obtained from different donor sources may have good in vitro proliferation ability. The invention also provides an application of the hepatic progenitor cell-like cell bank and cell lines obtained by the construction method.

There is described herein a cell culture medium comprising: a basal medium; an antibiotic; B27; Noggin; Y-27632; Human FGF10 or FGF7; preferably wherein there is an absence of a Wnt agonist. Methods and uses of the medium is also described.

The present invention relates to a cell structure including cells containing at least hepatocytes and vascular endothelial cells, and extracellular matrix component, wherein the extracellular matrix components are disposed between the cells, and a liver sinusoidal network is provided between the cells.

Provided are a composition and method for inducing direct conversion from a somatic cell into a myeloid cell and use thereof, in which differentiation from a somatic cell into a myeloid cell can be efficiently induced through the expression of a single direct conversion inducer without undergoing the pluripotency stage of induced pluripotent stem cells, and thus, the composition can be widely used as an effective preventive and therapeutic agent for immune diseases.

The disclosure generally relates to methods for generating cardiac fibroblast cells from epicardial cardiac progenitor cells, populations of cardiac fibroblast cells and uses thereof.
