Abstract: A high throughput method is provided for identifying agents capable of producing a desired biological response in whole cells. The method includes the steps of providing receptacles having a culture surface; placing different mixtures of single agents into selective ones of the receptacles according to a statistical design; and immobilizing the mixtures of single agents to the culture surface. The method further includes contacting the immobilized agents with the whole cells; and acquiring data which is indicative of a desired biological response in the contacted cells. The method also includes using statistical modeling of the acquired data to determine which mixtures of single agents and/or which single agents in these mixtures are effective in producing the desired biological response in the contacted cells.

Abstract: The present invention relates to a combination of placental stem cells and stem or progenitor cells derived from a second source, wherein the combination shows improved engraftment as compared to placental stem cells or stem cells from a second source, alone. The combination is referred to as a combined stem cell population. The invention also provides in vitro and in vivo methods for identifying and producing combined stem cell populations, and models of engraftment. In accordance with the present invention, the placental stem cells may be combined with, e.g., umbilical cord blood-derived stem or progenitor cells, fetal or neonatal stem cells or progenitor cells, adult stem cells or progenitor cells, hematopoietic stem cells or progenitor cells, stem or progenitor cells derived from bone marrow, etc.

Abstract: The present invention relates to cell adhesion promoting (“CAP”) peptide combinations that promote cell attachment or cell adhesion to culture surfaces that are otherwise cell adhesion resistant “CAR”. The invention provides combination of peptides that, when covalently coupled to a CAR layer such as hyaluronic acid that has been created on a polystyrene surface, promote cell attachment, growth differentiation, and execution of other desired cellular functions in culture.

Abstract: The present invention provides specific peptides identified as having cell adhesion, growth, expression or secretion-enhancing activities. Many of the peptides of the invention may be produced in large quantity by such means as chemical synthesis or recombinant DNA methodology. They may be non-specifically adsorbed, or chemically attached to a surface or, alternatively, formulated in a culture medium to produce the desired effect on cultured cells.

Abstract: The present invention provides methods for culturing, expanding and differentiating stem cells, particularly human embryonic stem cells. The methods comprise culturing the stem cells for a period of time on a collagen biofabric, particularly a collagen biofabric derived from the amniotic membrane, chorion, or both, from mammalian placenta.

Abstract: The present invention provides methods and compositions for the production of glial cells and oligodendrocytes from placenta stem cells. The invention further provides for the use of these glia and oligodendrocytes in the treatment of, and intervention in, for example, trauma, ischemia and degenerative disorders of the central nervous system (CNS), particularly in the treatment of demyelinating diseases such as multiple sclerosis.

Abstract: This invention relates, e.g., to a method for expanding mammalian acinar cells, comprising culturing the cells in a cell culture system comprising a cell culture medium and a cell attachment surface, under conditions wherein the acinar cells undergo a 3-4 fold expansion together with transdifferentiation into a modified cell phenotype (IP cells) showing characteristics of acinar cells and liver cells. The invention also relates to a method for transforming these IP cells to insulin-producing cells in vitro, comprising culturing the cells in a novel, defined medium. Also disclosed are suitable culture media for performing these methods, isolated cells having the phenotype of IP cells and/or produced by these methods, and kits for performing the methods.

Abstract: Surfaces useful for cell culture comprise a support to which is bound a CAR material, and, bound to the CAR material, collagen VI or a biologically active fragment or variant thereof and, optionally, one or more other ECM proteins (or fragments or variants thereof) such as elastin, fibronectin, vitronectin, tenascin, laminin, entactin, aggrecan, decorin, collagen I, collagen III, and collagen IV. Also, optionally present on the surface is one or more polycationic polymers, such as poly-D-lysine or poly-D-ornithine. This surface is used in cell culture to promote cell attachment, survival, and/or proliferation of a number of different cell types such as (a) liver cells (e.g., HepG2 tumor cells, and a newly discovered line of rat liver epithelial stem cells) (b) osteoblasts, such as the murine cell line MC3T3 cell line and (c) primary bone marrow cells. Kits comprising the surfaces and additional reagents are also disclosed.
