摘要:
Methods and compositions relating to the production of induced pluripotent stem cells (iPS cells) are disclosed. For example, induced pluripotent stem cells may be generated from CD34 + hematopoietic cells, such as human CD34 + blood progenitor cells, or T cells. Various iPS cell lines are also provided. In certain embodiments, the invention provides novel induced pluripotent stem cells with a genome comprising genetic rearrangement ofT cell receptors.
摘要:
Provided herein are methods for the in vitro differentiation of induced pluripotent stem cells, which have been expanded and/or maintained under defined conditions, into endodermal precursor cells (EPCs) that are capable of producing mono-hormonal beta cells.
摘要:
Methods for producing engineered induced pluripotent stem (iPS) cells are provided comprising introducing a first nucleic acid into somatic cells for integration into their genome and reprogramming the cells to produce engineered iPS cells having the nucleic acid integrated into their genome. For example, in certain aspects the cells are reprogrammed by introduction of a genetic element that expresses one or more reprogramming factor and culturing of the cells under conditions sufficient to produce reprogrammed cells.
摘要:
Methods and composition for differentiation of pluripotent stem cells are provided. For example, in certain aspects methods including priming stem cells for neural differentiation in a culture medium essentially free of growth factors such as FGF and TGFβ. As an advantage, the neural cells may be provided with improved consistency and purity.
摘要:
Methods and composition for maintenance of cardiomyocytes are provided. For example, in certain aspects methods including culturing the cardiomyocytes in a medium essentially free of serum or containing dialyzed serum to maintain long-term purity. In further aspects, methods for modulation of cardiomyocytes may be provided.
摘要:
Methods for the determination of tissue-specific genetic variation are provided. For example, in certain aspects methods for using iPS cell-derived specific cell types for differential molecular analysis of tissue-specific genetic variation are described.
摘要:
Methods and composition for the production of cardiomyocytes from differentiation of pluripotent stem cells are provided. For example, in certain aspects methods including differentiating pluripotent stem cells in a large volume of suspension culture in the presence of ROCK inhibitors are described. In further aspects, methods for differentiation of stem cells into cardiomyocytes that overcome variability between different stem cell clones and different batch of culture medium are provided.
