Abstract: Provided herein are methods of producing natural killer cells using a two-step expansion and differentiation method. Also provided herein are methods of suppressing tumor cell proliferation, of treating individuals having cancer or a viral infection, comprising administering the NK cells produced by the method to an individual having the cancer or viral infection.

Abstract: Provided herein are methods of suppressing tumor cell proliferation, of treating individuals having cancer or a viral infection, comprising contacting the tumor cells, or administering to the individual, placental perfusate, placental perfusate cells, or natural killer cells, e.g., placenta-derived intermediate natural killer cells, with an immunomodulatory compound or thalidomide.

Abstract: Provided herein are methods of producing erythrocytes from hematopoietic cells, particularly hematopoietic cells from placental perfusate in combination with hematopoietic cells from umbilical cord blood, wherein the method results in accelerated expansion and differentiation of the hematopoietic cells to more efficiently produce administrable erythrocytes. Further provided herein is a bioreactor in which hematopoietic cell expansion and differentiation takes place.

Abstract: The present invention relates to a combination of placental stem cells and stem or progenitor cells derived from a second source, wherein the combination shows improved engraftment as compared to placental stem cells or stem cells from a second source, alone. The combination is referred to as a combined stem cell population. The invention also provides in vitro and in vivo methods for identifying and producing combined stem cell populations, and models of engraftment. In accordance with the present invention, the placental stem cells may be combined with, e.g., umbilical cord blood-derived stem or progenitor cells, fetal or neonatal stem cells or progenitor cells, adult stem cells or progenitor cells, hematopoietic stem cells or progenitor cells, stem or progenitor cells derived from bone marrow, etc.
