Abstract

Provided are transplants and methods for augmenting formation and restoration of organ and tissue, for example, bone formation, by administering autologous or allogeneic human embryonic-like adult stem cells (ELA cells). Also provided is a method for augmenting formation of tissues and organs by administering a transplant having ELA stem cells or combination of ELA stem cells.

Claims (8)

1 . A transplant composition comprising: a T-cell- or NK-cell-suppressive amount of a non-expanded population of human early lineage adult (ELA) stem cells, an immune cell population comprising plasmacytoid dendritic cells, and a cryopreservative, wherein the human ELA stem cells express at least one of Oct4, Nanog and Sox2, and do not detectably express CD13, CD45, CD90 or CD34, and wherein the transplant composition is without detectable erythrocyte cells.

2 . The transplant composition of claim 1 , wherein the transplant is an allograft.

3 . The transplant composition of claim 2 , wherein the allograft is not MHC matched to the human transplant recipient.

4 . The transplant composition of claim 1 , wherein the transplant includes at least one component selected from the group consisting of plasma, cell culture medium, an antibacterial agent, a growth factor, a vitamin, and a hormone.

5 . The transplant composition of claim 1 , further comprising a carrier having a matrix, wherein the matrix conforms substantially to its insertion site and provides a structurally stable, three dimensional surface that retains the transplant and supports ingrowth of ELA stem cells into the matrix at the insertion site.

6 . The transplant composition of claim 1 , wherein the transplant promotes the formation of a tissue selected from the group consisting of: connective tissue; bone; and dermal tissue.

7 . The transplant composition of claim 1 , wherein the human ELA stem cell numbers in the transplant comprise about 5000 to about 5×10 6 human ELA stem cells.

8 . The transplant composition of claim 1 , wherein the transplant composition is cryogenically frozen.
