The present invention relates to monolayer cardiac differentiation techniques utilizing defined conditions providing feeder-free monolayer culture systems, serum-based or serum free, and applicable to both healthy control and patient derived stem cells.

The present invention provides an artificial tissue culture comprising a heterogeneous population of cells of at least two different tissue sections, wherein said tissue sections are in a three dimensional structure, method of generating such a tissue and kits suitable for said method or maintain a three dimensional tissue culture.

Described is an optimized process for parvovirus production including an essentially serum-free medium which is suitable to increase parvovirus production compared to a standard medium, preferably for H-1PV production.

The present invention aims to provide a method for preparing urothelial cells that can be applied to the treatments of urologic diseases, particularly, diseases caused by urothelial cell damage, diseases caused by loss of urothelial cells and dysfunction, and the like, urothelial cells prepared by said method, and a medium for inducing (generating) urothelial cells. Urothelial cells prepared by a method for inducing a urothelial cell, including a step of introducing at least one member selected from the group consisting of

FOXA1 (Forkhead box A1) gene or an expression product thereof,
TP63 (tumor protein P63) gene or an expression product thereof,
MYCL (L-Myc) gene or an expression product thereof, and
KLF4 (Kruppel-like factor 4) gene or an expression product thereof
to a mammalian somatic cell as an exogeneous factor can be applied to the treatment of urologic diseases.

A method for meat production by in vitro cell culture includes isolating tissue from an animal or plant source and making a cell suspension of cells, and growing the cells into a solid or semi-solid structure that mimics an animal organ by growing the cells on a food-grade scaffold in a culture medium. Culture medium comprising growth factor of (i) genetically same or similar species to the cells and/or (ii) genetically same genus to the cells is used. Expression of one or more proteins in the growing cells may be increased by altering a level of one or more micro RNAs that regulate expression of the protein. Additionally, the growing cells may be co-cultured with bioengineered cells that secrete growth factors and cytokines that support the growth of the cells in situ. The co-culturing technique reduces or eliminates the need for animal-derived fetal bovine serum in the culture medium.

An in vitro method for identifying, isolating and/or enriching primate naive pluripotent stem cells, the method including analyzing transcription of a type 7 long terminal repeat (LTR7) nucleic acid sequence of a type H human endogenous retrovirus (HERVH) (LTR7/HERVH-associated transcription), and identifying, isolating and/or enriching primate naive pluripotent stem cells based on LTR7/HERVH-associated transcription, wherein LTR7/HERVH-associated transcription is a marker for primate naive pluripotent stem cells. An isolated in vitro population of primate naive pluripotent stem cells is obtained by the method, wherein in the cells LTR7/HERVH-associated transcription is elevated in comparison to control cells, wherein control cells are primed pluripotent stem cells or differentiated cells.

The present disclosure relates to a neural cell population, a neural cell-containing preparation, and a method for producing the population and preparation. More particularly, the present invention relates to a neural cell population derived from intraoral mesenchymal cells, wherein a proportion of normal diploid cells is 80% or more, a preparation containing the neural cell population, and a method for producing the population and the preparation.

Described herein are methods, compositions, and kits for forming engineered in vitro biomimetic, three-dimensional, tubular organoid structures by directed differentiation of human pluripotent stem cells within tubular channels formed in a hydrogel.

Compositions, kits, and methods for preparing nutrient compositions are provided. A nutrient composition can be a food composition such as a dairy composition. A nutrient composition may be produced by an engineered cell composition. Compositions, kits, and methods for preparing engineered cell compositions for producing nutrient compositions are also provided. An engineered cell composition may comprise genetically engineered cells, such as genetically engineered mammary or mammary-like cells. An engineered cell composition can be derived from mammalian stem cells, such as non-mammary adult stem cells. Related methods of characterization, such as for characterizing the engineered cell compositions or the nutrient compositions, are also provided.

Methods are provided for the production of photoreceptor cells and photoreceptor progenitor cells from pluripotent stem cells. Additionally provided are compositions of photoreceptor cells and photoreceptor cells, as well as methods for the therapeutic use thereof. Exemplary methods may produce substantially pure cultures of photoreceptor cells and/or photoreceptor cells.
