Abstract: The present invention is of methods of establishing and propagating human embryonic stem cell lines using feeder cells-free, xeno-free culture systems and stem cells which are capable of being maintained in an undifferentiated, pluripotent and proliferative state in culture which is free of xeno contaminants and feeder cells.

Abstract: An isolated primate embryonic cell is provided as well as cell cultures and cell lines derived therefrom. Also provided are methods of generating and using such cells.

Abstract: Stem cells, stem cell lines and differentiated cells, tissues and organs which carry disease-causing mutations are provided. There is also provided a method of identifying agents suitable for treating disorders associated with at least one disease-causing mutations such as myotonic dystrophy and van Waardenburg syndrome.

Abstract: A cell culture comprising human foreskin cells, the human foreskin cells being capable of maintaining stem cells in an undifferentiated state when co-cultured therewith.

Abstract: A cell culture comprising human foreskin cells, the human foreskin cells being capable of maintaining stem cells in an undifferentiated state when co-cultured therewith.

Abstract: The present invention is of methods of establishing and propagating human embryonic stem cell lines using feeder cells-free, xeno-free culture systems and stem cells which are capable of being maintained in an undifferentiated, pluripotent and proliferative state in culture which is free of xeno contaminants and feeder cells.

Abstract: A method of generating cells predominantly displaying at least one characteristic associated with a cardiac phenotype is disclosed. The method comprises (a) partially dispersing a confluent cultured population of human stem cells, thereby generating a cell population including cell aggregates; (b) subjecting said cell aggregates to culturing conditions suitable for generating embryoid bodies; (c) subjecting said embryoid bodies to culturing conditions suitable for inducing cardiac lineage differentiation in at least a portion of the cells of said embryoid bodies, said culturing conditions suitable for inducing cardiac lineage differentiation including adherence of said embryoid bodies to a surface, and culture, medium supplemented with serum, thereby generating cells predominantly displaying at least one characteristic associated with a cardiac phenotype.

Abstract: The present invention discloses insulin producing cells derived from human embryonic stem cells. Methods of generating, enriching, selecting, cloning and isolating populations of insulin-producing embryonic cell lines are disclosed. Insulin production in these cells can be glucose responsive or otherwise regulatable. Advantageously, these insulin producing cells can be stable cell lines derived from stable transfectants of hESC. Methods of using these cells, cell populations or cell lines particularly for cell replacement therapy are also disclosed.

Abstract: A cell culture comprising human foreskin cells, the human foreskin cells being capable of maintaining stem cells in an undifferentiated state when co-cultured therewith.

Abstract: The invention is a population of embryonic endothelial cells produced in vitro from human embryonic stem cells. The cells produce platelet endothelial cell adhesion molecule-1 and are vasculogenic. The cells may be combined with a cell support substrate, seeded on a polymer matrix, or combined with a cell-support substrate that is infused into a polymer matrix. The cells may also be injected directly into a tissue site.

Abstract: A method of establishing a clonal embryonic stem cell line capable of sustaining a phenotype of normal embryonic stem cells following at least eight months of in vitro culture is disclosed. The method is effected by culturing an individual embryonic stem cell for at least eight months in a serum-free medium, thereby establishing the clonal embryonic stem cell line capable of sustaining said phenotype of normal embryonic stem cells following at least eight months of in vitro culture.
