Abstract: This disclosure provides an improved system for culturing human pluripotent stem cells. Traditionally, pluripotent stem cells are cultured on a layer of feeder cells (such as mouse embryonic fibroblasts) to prevent them from differentiating. In the system described here, the role of feeder cells is replaced by components added to the culture environment that support rapid proliferation without differentiation. Effective features are a suitable support structure for the cells, and an effective medium that can be added fresh to the culture without being preconditioned by another cell type. Culturing human embryonic stem cells in fresh medium according to this invention causes the cells to expand surprisingly rapidly, while retaining the ability to differentiate into cells representing all three embryonic germ layers. This new culture system allows for bulk proliferation of pPS cells for commercial production of important products for use in drug screening and human therapy.

Abstract: The present invention is directed to the composition and use of a modified Herpes Simplex Virus Type 2 (HSV-2) as a medicament in the treatment of cancer. The modified HSV-2 has fusogenic activity, and comprises a modified/mutated ICP10 polynucleotide encoding a polypeptide having ribonucleotide reductase activity and lacking protein kinase activity.
Abstract: A hierarchy of endothelial colony forming cells (EPCs) was identified from mammalian cord blood, umbilical vein and aorta. A newly isolated cell named high proliferative potential-endothelial colony forming cell (HPP-ECFC) was isolated and characterized. Single cell assays were developed that test the proliferative and clonogenic potential of endothelial cells derived from cord blood, or from HUVECs and HAECs. EPCs were found to reside in vessel walls. Use of a feeder layer of cells derived from high proliferative potential-endothelial colony forming cells (HPP-ECPCS) from human umbilical cord blood, stimulates growth and survival of repopulating hematopoietic stem and progenitor cells. Stimulation of growth and survival was determined by increased numbers of progenitor cells in in vitro cultures and increased levels of human cell engraftment in the NOD/SCID immunodeficient mouse transplant system.

Abstract: The purpose of the present invention is to provide a method and a culture medium which are capable of efficiently inducing the differentiation of pluripotent stem cells such as ES cells and iPS cells into desired cells by a simple means. The differentiation of pluripotent stem cells can be induced by culturing mammal-derived pluripotent stem cells in a differentiation culture medium that does not contain at least one amino acid selected from the group consisting of methionine, leucine, cysteine, tyrosine and arginine. Also provided is a differentiation-inducing culture medium which does not contain at least one amino acid selected from the group consisting of methionine, leucine, cysteine, tyrosine and arginine.

Abstract: The present invention relates to therapeutic use of a combination of Myxoma virus, including in combination with rapamycin. Treatment with rapamycin enhances the ability of Myxoma virus to selectively infect cells that have a deficient innate anti-viral response, including cells that are not responsive to interferon. The combination of rapamycin and Myxoma virus can be used to treat diseases characterized by the presence of such cells, including cancer. The invention also relates to therapeutic use of Myxoma virus that does not express functional M135R.

Abstract: A method of targeting bacterially-derived, intact minicells to specific, non-phagocytic mammalian cells employs bispecific ligands to deliver nucleic acids efficiently to the mammalian cells. Bispecific ligands, comprising (i) a first arm that carries specificity for a bacterially-derived minicell surface structure and (ii) a second arm that carries specificity for a non-phagocytic mammalian cell surface receptor are useful for targeting minicells to specific, non-phagocytic mammalian cells and causing endocytosis of minicells by non-phagocytic cells.
