    摘要: The present invention provides undifferentiated human embryonic stem cells, methods of cultivation and propagation and production of differentiated cells. In particular it relates to the production of human ES cells capable of yielding somatic differentiated cells in vitro, and committed progenitor cells such as neural progenitor cells capable of giving rise to mature somatic cells including neural cells and/or glial cells and uses thereof. The invention also provides methods that generate in vitro and in vivo models of controlled differentiation of ES cells towards the neural lineage. The model and the cells generated along the pathway of neural differentiation may be used for the study of the cellular and molecular biology of human neural development, for the discovery of genes, growth factors, and differentiation factors that play a role in neural differentiation and regeneration, for drug discovery and for the development of screening assays for teratogenic, toxic and neuroprotective effects.

    摘要: The present invention provides a cell marker that is characterized by binding to a GCTM-5 antibody of active fragment. The cell marker identifies a unique sub-population of stem cells that show characteristics of hepatic or pancreatic stem cells or hepatic or pancreatic progenitor cells. More specifically the marker is an early liver marker, which could prove a useful tool for the isolation and identification of liver and pancreatic progenitors for both diseased adult liver and differentiating human embryonic stem cells.

    摘要: The present invention provides methods, media and compositions capable of modulating the differentiation of stem cells. Applicants have discovered that agonists of lysophospholipid receptors and ligands of class III tyrosine kinase receptors are useful in preventing the spontaneous differentiation of stem cells. The ligands and agonists may be used alone, or in combination where they have a synergistic effect. Also provided are cells produced using the methods and media, and methods of treating stem cell related diseases using the compositions described herein. Methods of identifying compounds useful in finding other agents useful in the modulation of stem cell differentiation are also disclosed.

    摘要: The present invention provides a preparation of undifferentiated embryonic stem (ES) cells sustainable for a prolonged period in an undifferentiated state which will undergo stem cell renewal or somatic differentiation. Preferably the cells are capable of somatic differentiation in vitro and are inclined to differentiate away from an extraembryonic lineage. The present invention also provides method of culturing embryonic stem (ES) cells to improve stem cell maintenance and persistence in culture. The method also provides a culture of ES cells prepared by the method as well as differentiated cells derived from the embryonic cells resulting from directed differentiation procedures provided by the present invention.
