Abstract

The present invention provides novel compositions comprising multipotent cells or microvascular tissue, wherein the cells or tissue has been sterilized and/or treated to inactivated viruses, and related methods of using these compositions to treat or prevent tissue injury or disease in an allogeneic subject.

Claims (18)

1. A composition comprising enriched or isolated multipotent cells from dissociated mammalian tissue, wherein the composition is sterilized by irradiation, and wherein the composition has angiogenic or anti-inflammatory activity.

2. The composition of claim 1 , wherein the cells or tissue are not cultured.

3. The composition of claim 1 , wherein the composition comprises ten or more components of multipotent cells.

4. The composition of claim 1 , wherein at least 50% of the multipotent cells present in the composition will not proliferate.

5. The composition of claim 1 , wherein the composition comprises one or more vessel wall extracellular matrix components.

6. The composition of claim 1 , wherein the composition comprises one or more growth factors.

7. The composition of claim 1 , wherein the composition comprises one or more angiogenic agents.

8. The composition of claim 1 , wherein the dissociated mammalian tissue is a non-embryonic tissue.

9. The composition of claim 8 , wherein the non-embryonic tissue is adipose tissue, skin, bone, tendon tissue, post-partum tissue, umbilical cord tissue, placental tissue, bone marrow or muscle tissue.

10. A composition comprising dissociated mammalian tissue, wherein the composition comprises multipotent cells rendered nonviable, and wherein the composition has angiogenic or anti-inflammatory activity.

11. The composition of claim 10 , wherein the composition is sterilized by irradiation.

12. The composition of claim 10 , wherein viruses within the composition are inactivated.

13. The composition of claim 10 , wherein the cells or tissue are not cultured.

14. The composition of claim 10 , wherein the composition comprises one or more vessel wall extracellular matrix components.

15. The composition of claim 10 , wherein the composition comprises one or more growth factors.

16. The composition of claim 10 , wherein the composition comprises one or more angiogenic agents.

17. The composition of claim 10 , wherein the dissociated mammalian tissue is a non-embryonic tissue.

18. The composition of claim 17 , wherein the non-embryonic tissue is adipose tissue, skin, bone, tendon tissue, post-partum tissue, umbilical cord tissue, placental tissue, bone marrow or muscle tissue.
