The present invention provides compositions and methods of using embryonic-like stem cells that originate from a post-partum placenta with conventional cord blood compositions or other stem or progenitor cells. The embryonic-like stem cells can be used alone or in a mixture with other stem cell populations. In accordance with the present invention, the embryonic-like stem cells may be mixed with other stem cell populations, including but not limited to, umbilical cord blood, fetal and neonatal hematopoietic stem cells and progenitor cells, human stem cells and progenitor cells derived from bone marrow. The embryonic-like stem cells and the mixed populations of embryonic-like stem cells and stem cells have a multitude of uses and applications, including but not limited to, therapeutic uses for transplantation and treatment and prevention of disease, and diagnostic and research uses.

What is claimed is: 1. A composition comprising human stem or progenitor cells and isolated human placental stem cells that are SH2+, SH3+, SH4+ and OCT-4+, wherein said placental stem cells are obtained from a placenta that has been drained of cord blood and flushed to remove residual blood. 2.
What is claimed is: 1. A composition comprising human stem or progenitor cells and isolated human placental stem cells that are SH2+, SH3+, SH4+ and OCT-4+, wherein said placental stem cells are obtained from a placenta that has been drained of cord blood and flushed to remove residual blood. 2. A composition comprising human umbilical cord blood cells and isolated human placental stem cells that are SH2+, SH3+, SH4+ and OCT-4+, wherein said placental stem cells are obtained from a placenta that has been drained of cord blood and flushed to remove residual blood. 3. A composition comprising human stem or progenitor cells and isolated human placental stem cells that are SH2+, SH3+, SH4+, SSEA3- and SSEA4-, wherein said placental stem cells are obtained from a placenta that has been drained of cord blood and flushed to remove residual blood. 4. A composition comprising human umbilical cord blood cells and isolated human placental stem cells that are SH2+, SH3+, SH4+, SSEA3- and SSEA4-, wherein said placental stem cells are obtained from a placenta that has been drained of cord blood and flushed to remove residual blood. 5. The composition of any of claim 1, 2, 3 or 4 that is contained in a container. 6. The composition of claim 5 wherein the container is sealed, air tight, and sterile. 7. The composition of claim 1 or claim 3 wherein the stem or progenitor cells are from umbilical cord blood or placental blood, fetal or neonatal hematopoietic stem or progenitor cells, adult cells or bone marrow stem or progenitor cells. 8. The composition of claim 7 wherein the stem or progenitor cells are fetal or neonatal hematopoietic stem or progenitor cells. 9. The composition of claim 8 wherein a plurality of the hematopoietic stem or progenitor cells are CD34+ and CD38-. 10. The composition of claim 2 or claim 4 wherein a plurality of the umbilical cord blood stem cells are CD34+ and CD38+. 11. The composition of claim 2 or claim 4 wherein a plurality of the umbilical cord blood stem cells are CD34+ and CD38+. 12. The composition of claim 1 or 2 wherein the placental stem cells exhibit at least one of the following cell surface markers: CD10, CD29, CD44, CD54, or CD90, or lack at least one of the following cell surface markers: CD34, CD45, SSEA3, or SSEA4. 13. A kit comprising a composition of claim 1 or 3 wherein said stem or progenitor cells are in a first container and said placental stem cells are in a second container. 14. A composition which comprises human stem or progenitor cells from umbilical cord blood supplemented with a plurality of isolated human placental stem cells that are SH2+, SH3+, SH4+ and OCT-4+, wherein said placental stem cells are obtained from a placenta that has been drained of cord blood and flushed to remove residual blood, and wherein the ratio of placental stem cells to said stem or progenitor cells is at least 1:1 in numbers. 15. The composition of claim 3 or 4 wherein the placental stem cells exhibit at least one of the following cell surface markers: CD10, CD29, CD44, CD54, CD90, or OCT-4, or lack at least one of the following cell surface markers: CD34 or CD45. 16. A kit comprising a composition of claim 2 or claim 4 wherein said umbilical cord blood cells are in a first container and said placental stem cells are in a second container. 17. A composition which comprises a number of human stem or progenitor cells from umbilical cord blood supplemented with a number of isolated human placental stem cells that are SH2+, SH3+, SH4+, SSEA3- and SSEA431 , wherein said placental stem cells are obtained from a placenta that has been drained of cord blood and flushed to remove residual blood, and wherein the ratio of the number of placental stem cells to the number of said stem or progenitor cells is at least 1:1.
