Abstract: Methods of generating and expanding human hemangio-colony forming cells and non-engrafting hemangio cells in vitro and methods of expanding and using such cells are disclosed. The methods permit the production of large numbers of hemangio-colony forming cells, non-engrafting hemangio cells as well as derivative cells, such as hematopoietic and endothelial cells. The cells obtained by the methods disclosed may be used for a variety of research, clinical, and therapeutic applications. Human non-engrafting hemangio cells are a novel progenitor cell population that is related to but distinct from the hemangioblast and human hemangio-colony forming cells. The invention also provides compositions, preparations, and solutions comprising hemangio-colony forming cells, non-engrafting hemangio cells or cells differentiated therefrom.

Abstract: Methods for generating enucleated erythroid cells using pluripotent stem cells are provided. The methods permit the production of large numbers of cells. The cells obtained by the methods disclosed may be used for a variety of research, clinical, and therapeutic applications. Methods for generating megakaryocyte and platelets are also provided.

Abstract: This disclosure provides the first description of hESC-derived cells transplanted into human patients. Results are reported for one patient with each of Stargardt's Macular Dystrophy (SMD) and Dry Age-Related Macular Degeneration (AMD). Controlled hESC differentiation resulted in near-100% pure RPE populations. Immediately after surgery, hyperpigmentation was visible at the transplant site in both patients, with subsequent evidence the cells had attached and integrated into the native RPE layer. No signs of inflammation or hyperproliferation were observed. The hESC-derived RPE cells have shown no signs of rejection or tumorigenicity at the time of this report. Visual measurements suggest improvement in both patients.

Abstract: This invention relates to methods for improved cell-based therapies for retinal degeneration and for differentiating human embryonic stem cells and human embryo-derived into retinal pigment epithelium (RPE) cells and other retinal progenitor cells.

Abstract: Methods for production of platelets from pluripotent stem cells, such as human embryonic stem cells (hESCs) and induced pluripotent stem cells (iPSCs) are provided. These methods may be performed without forming embryoid bodies or clusters of pluripotent stem cells, and may be performed without the use of stromal inducer cells. Additionally, the yield and/or purity can be greater than has been reported for prior methods of producing platelets from pluripotent stem cells. Also provided are compositions and pharmaceutical preparations comprising platelets, preferably produced from pluripotent stem cells.

Abstract: The present invention generally relates to novel preparations of mesenchymal stromal cells (MSCs) derived from hemangioblasts, methods for obtaining such MSCs, and methods of treating a pathology using such MSCs. The methods of the present invention produce substantial numbers of MSCs having a potency-retaining youthful phenotype, which are useful in the treatment of pathologies.

Abstract: Methods for generating embryos using pluripotent stem cells are provided. The subject methods include methods for generating chimeric embryos, wherein only a subset of the cells of each embryo are genetically identical to the pluripotent stem cells used in the generation process. The subject methods also include methods for generating embryos that are identical or are essentially genetic clones of the pluripotent stem cells (e.g., the resulting embryos are substantially identical, genetically, to the pluripotent stem cells used in the generation process).
