Abstract:
The present invention is related generally to embryonic-like stem cells isolated from human umbilical cord blood, designated herein as cord blood-stem cells (CB-SCs), which display the characteristics of embryonic stem cells and hematopoietic cells. These cells have the capability of proliferation and are able to differentiate to multiple types of cells. In addition, the CB-SC display low immunogenicity and immune regulation. These cells are, therefore, suitable for use in stem cell-based therapies for the treatment of diseases such as Parkinson's disease, diabetes, spinal cord damage, multiple sclerosis, cardiovascular disease, stroke and birth defects.
Abstract:
The invention describes methods for production of novel composition of glycans, glycomes, from human multipotent stem cells. The invention is further directed to methods for modifying the glycomes and analysis of the glycomes and the modified glycomes. Furthermore the invention is directed to stem cells carrying the modified glycomes on their surfaces.
Abstract:
The present invention relates a method for activating a CD8 T cell which comprises following steps: (1) separating CD8 T cells; and (2) cultivating in vitro with a culture broth containing cytokines such as GM-CSF, IFN-γ, TNF-α, lectin, IL-2 and IL-4; and a therapeutic composition for preventing or treating infectious diseases of virus" which comprises the CD8 T cell activated by the method.
Abstract:
The present invention provides cord blood hematopoietic progenitor cells treated with fucosyltransferase. Such cells exhibit increased homing and enhanced bone marrow engraftment, and are useful in methods of bone marrow transplantation.
Abstract:
The invention feature methods and compositions for treating hematopoietic disorders, inflammatory conditions, and cancer and providing stem cell therapy in a mammal.
Abstract:
The present invention discloses a method of generation of antigen presenting cells, comprising: a. collecting said cells from a subject, b. activating said collected cells; c. culturing and optionally expanding ex vivo said activated cells; d. treating said cultured and optionally expanded cells with DNA hypomethylating agents so that said cells concomitantly express multiple tumor associated antigens. The cells obtainable according to the method of the present invention, as well as the cellular components thereof whether alone or in combination with said cells, are useful for prevention and treatment of malignancies of different histotype that constitutively express one or more of the multiple tumor associated antigens that are expressed in said cells. Conveniently, said cells and/or cellular components are in the form of a vaccine. Said vaccines are advantageous over the prior art in that as they concomitantly express multiple/all methylation-regulated tumor associated antigens.

Abstract:
The invention relates to a method for lymphoid tissue-specific cell production from hematopoietic progenitor cells in unique, three-dimensional culture devices, in the presence of lymphoreticular stromal cells and in the absence of exogenously added growth factors. The resulting differentiated progeny. The lymphoid tissue-specific cells may be isolated at any sequential stage of differentiation and further expanded. The lymphoid tissue-specific cells also may be genetically altered at any stage of the process.
