Abstract: Synthetic bacterial messenger RNA can be used to prepare autologous, allogenic or direct nucleic acid cancer vaccines. Cancer cells are transfected either in vitro or in vivo with mRNA obtained from DNA that encodes an immunogenic bacterial protein. An immune response to the cancer is generated from direct administration of the mRNA in vivo or administration of vaccines prepared from cancer cells in vitro. Codon modification of the mRNA can optimize expression of an immunogenic polypeptide in cancer cells.

Abstract: Chimeric expression constructs encoding an immunogenic polypeptide fused to a lactadherin domain are described. The compositions are useful for delivery of antigens to different cells, including cancer cells.

Abstract: The present invention relates to the field of progenitor cells. More specifically, the present invention provides compositions and methods for isolating endocrine progenitor cells from pancreatic tissue. In certain embodiments, the method comprises the steps of (a) providing a pancreatic tissue sample; (b) isolating cells positive for CD133+; and (c) culturing the isolated cells in defined media for at least about 4 days.

Abstract: Methods for deriving and cultivating human embryonic stem (ES) cells and maintaining their pluripotency in culture is provided by utilizing secreted products obtained from the culture medium of human embryonic gem (EG) cell derivatives, such as embryoid body-derived cells. Substrates include compounds such as collagen I, fibronectin, or superfibronectin, or extracellular matrix, typically human derived.

Abstract: The presence of the cell surface marker CD133 or the presence of a glycosylated form of the prominin-1 gene product on adult pancreatic cells is used to identify pancreatic endocrine progenitor cells, and useful in methods of isolation and enrichment. Isolated pancreatic endocrine progenitor cells can be used for cell based therapy for insulin-dependent diabetes and pancreatectomy patients.

Abstract: Methods, devices and kits are provided for isolating or enriching multicellular embryonic stem (ES) cell colonies from a mixture of multicellular ES cell colonies and single ES cells present in a cellular suspension, by utilizing a filtration matrix that selectively excludes passage of multicellular ES cell colonies. Isolated or enriched multicellular ES cell colonies can be used for propagating pluripotent ES cells.

Abstract: Methods for deriving and cultivating human embryonic stem (ES) cells and maintaining their pluripotency in culture is provided by utilizing human umbilical cord blood derived stem cells or secreted proteins obtained from the culture medium of human umbilical cord blood derived stem cells.

Abstract: The invention is directed to novel cells that are derived from human embryoid bodies. Such embryoid body-derived (EBD) cells are relatively uncommitted or progenitor (e.g., pluripotent) cells. EBD cells, while not immortal, display long-term proliferation in culture with a normal karyotype and can be cryopreserved and cloned. They can be efficiently transfected with retroviruses and lentivirus and genetically manipulated. Although they have a developmentally broad multilineage expression profile, they do not form tumors when injected into severe combined immunodeficiency (SCID) mice. As a result, EBD cells have a variety of uses, for example, in transplantation therapies.
