Abstract: The present invention is based on the discovery of genetic engineered induced pluripotent stem cells (iPSCs) that produce one or more therapeutic entities such as antibodies and nucleic acids that when administered to a subject, will treat or prevent disease. The present invention also combines EMV technology with iPSC technology creating a powerful new drug delivery platform.

Abstract: The invention belongs to the fields of cell biology and medicine, and relates to the medical use of NOTCH4 or the medical use of NOTCH4 inhibitors. In particular, the invention relates to use of NOTCH4 protein or NOTCH4 gene for manufacture of a medicament for promoting hematopoietic stem/progenitor cell differentiation and megakaryocyte differentiation in a mammal, a medicament for treating megakaryocyte dysplasia, or a medicament for promoting platelet production. The invention can effectively promote the production of hematopoietic stem/progenitor cells and megakaryocytes in vitro, thereby significantly improving the efficiency of platelet production in vitro, and having a good application prospect.

Abstract: The present invention is based on the seminal discovery that cord blood (CB) and adult bone marrow (BM) CD34+ cells can be reprogrammed to early stem cells. The invention provides the reprogramming of CB and adult bone marrow (BM) CD34+ cells from subjects without any pre-treatment. Provided are methods for reprogramming blood cells of a subject. Also provided are methods of disease modeling and methods of generating subject-specific differentiated cells. In addition, the invention provides methods of identifying an agent that alters a function of subject-specific differentiated cells as well as isolated pluripotent or multipotent stem cells reprogrammed from blood cells.

Abstract: Human pluripotential embryonic stem cell cultures are provided, as are human feeder cells useful for growing the human embryonic stem cells, conditioned medium obtained from cultures of the human feeder cells, and factors derived from the conditioned medium. Also provided are methods of growing human embryonic stem cells in the presence of the human feeder cells, the conditioned medium, the factors derived from the conditioned medium, or a combination thereof. In addition to the human embryonic stem cell cultures grown according to such methods, isolated human embryonic stem cells obtained from such human embryonic stem cell cultures are provided, as are methods of using such isolated cells.

Abstract: The invention provides methods and compositions for the modulation of systemic immune responses by transplantation of hematopoietic stem cells transduced with genes encoding antigens and antigen presenting cell regulatory molecules. The invention includes bi-cistronic lentiviral expression vectors adapted for antigen expression in antigen presenting cells for use in DNA vaccines directed against pathogens and tumor antigens as well as for the treatment of autoimmune disease and for the establishment of antigen tolerance.
