    摘要： This invention provides a system for producing differentiated cells from a stem cell population for use wherever a relatively homogenous cell population is desirable. The cells contain an effector gene under control of a transcriptional control element (such as the TERT promoter) that causes the gene to be expressed in relatively undifferentiated cells in the population. Expression of the effector gene results in depletion of undifferentiated cells, or expression of a marker that can be used to remove them later. Suitable effector sequences encode a toxin, a protein that induces apoptosis; a cell-surface antigen, or an enzyme (such as thymidine kinase) that converts a prodrug into a substance that is lethal to the cell. The differentiated cell populations produced according to this disclosure are suitable for use in tissue regeneration, and non-therapeutic applications such as drug screening.

    摘要： Genes that are up- or down-regulated during differentiation provide important leverage by which to characterize and manipulate early-stage pluripotent stem cells. Over 35,000 unique transcripts have been amplified and sequenced from undifferentiated human embryonic stem cells, and three types of differentiated progeny. Statistical analysis of the assembled transcripts identified genes that alter expression levels as differentiation proceeds. The expression profile provides a marker system that has been used to identify particular culture components for maintaining the undifferentiated phenotype. The gene products can also be used to promote differentiation; to assess other relatively undifferentiated cells (such as cancer cells); to control gene expression; or to separate cells having desirable characteristics. Manipulation of particular genes can be used to forestall or focus the differentiation process, en route to producing a specialized homogenous cell population suitable for human therapy.

    摘要： Methods and materials for culturing primate-derived primordial stem cells are described. In one embodiment, a cell culture medium for growing primate-derived primordial stem cells in a substantially undifferentiated state is provided which includes a low osmotic pressure, low endotoxin basic medium that is effective to support the growth of primate-derived primordial stem cells. The basic medium is combined with a nutrient serum effective to support the growth of primate-derived primordial stem cells and a substrate selected from the group consisting of feeder cells and an extracellular matrix component derived from feeder cells. The medium further includes non-essential amino acids, an anti-oxidant, and a first growth factor selected from the group consisting of nucleosides and a pyruvate salt.

    摘要： The present application describes the new methods for the differentiation of primate pluripotent stem cells into cardiomyocyte-lineage cells. The methods utilize sequential culturing of the primate pluripotent stem cells in certain growth factors to produce cardiomyocyte-lineage cells. In certain embodiments of the invention, the population of cells produced by the sequential culturing is further enriched for cardiomyocyte-lineage cells so as to produce a higher percentage of those cells.
