Abstract: Methods, cells, and compositions of matter are disclosed for performing stem cell transplants in patients that have not been previously immunosuppressed. Specific disclosed are methods of matching, methods of treating the stem cell graft, and use of engraftment-assisting cells and agents.

Abstract: Disclosed are methods, compositions of matter, and cells, useful for the treatment of autism, social integrative disorders, and various cognitive abnormalities. The invention discloses, inter alia, means of substantially ameliorating or reversing the progression of autism through the administration of autologous and/or allogeneic stem cells, alone or in combination with mobilization agents. The use of stem cells and cells naturally possessing or endowed with angiogenic and anti-inflammatory activity are disclosed for autism either alone or in combination with various therapeutic interventions.

Abstract: Disclosed are methods of preparing and using placentally-derived stem cells and compositions useful for the treatment of cancer. Said stem cells and compositions function through inducing a “guided differentiation” program in cancer cells, thereby reducing malignancy. Further extension of the invention pertains to augmenting ability of administered cells to induce differentiation through the co-administration of known differentiation inducing agents. Within the context of this disclosure, methods for inducing host responses to cancer are also described.

Abstract: A method of increasing the growth of stem cells by mixing the stem cells with a growth medium that has been conditioned by an incubation with placental tissue. The method increases the expansion of the stem cell population.

Abstract: Methods, cells and compositions of matter are provided for treatment of erectile dysfunction using stem cell therapy. In particular, various stem cells are modified or administered freshly isolated in order to induce smooth muscle regeneration, neural regeneration, and restoration of endothelial function. In some embodiments endogenous stem cells are mobilized or activated to achieve therapeutic benefit. In other embodiments compositions derived from stem cells are utilized for treatment of erectile dysfunction.
