Cells present in processed lipoaspirate tissue are used to treat patients, including patients with renal conditions, diseases or disorders. Methods of treating patients include processing adipose tissue to deliver a concentrated amount of stem cells obtained from the adipose tissue to a patient. The methods may be practiced in a closed system so that the stem cells are not exposed to an external environment prior to being administered to a patient. Accordingly, in a preferred method, cells present in processed lipoaspirate are placed directly into a recipient along with such additives necessary to promote, engender or support a therapeutic renal benefit.

1. A method for treating acute tubular necrosis (ATN) in a patient, comprising: identifying a patient with ATN; andproviding to the patient's renal vasculature an amount of a concentrated population of cells comprising adipose-derived stem cells sufficient to restore blood flow to an ischemic region
1. A method for treating acute tubular necrosis (ATN) in a patient, comprising: identifying a patient with ATN; andproviding to the patient's renal vasculature an amount of a concentrated population of cells comprising adipose-derived stem cells sufficient to restore blood flow to an ischemic region of the kidney of said patient. 2. The method of claim 1, wherein said patient is human. 3. The method of claim 1, wherein the concentrated population of cells comprising adipose-derived stem cells further comprises adipose-derived progenitor cells. 4. The method of claim 1, wherein the ATN is ischemic ATN. 5. The method of claim 1, wherein the ATN is nephrotoxic ATN. 6.

The method of claim 1, wherein said concentrated population of cells comprising adipose-derived stem cells is provided to said patient in multiple doses. 8. The method of claim 1, further comprising providing one or more additives to said patient or to said concentrated population of cells comprising adipose-derived stem cells. 9. The method of claim 1, wherein said concentrated population of cells comprising adipose-derived stem cells further comprises an additive. 10. The method of claim 9, wherein said additive is selected from the group consisting of a disaggregation agent, an immunosuppressive agent, and an angiogenic factor. 11. The method of claim 9, wherein said additive is selected from the group consisting of collagenase, trypsin, lipase, hyalurondiase, deokyribonuclease, Liberase H1, a tissue or cell re-aggregation inhibitor, and pepsin, or any combination thereof. 12. The method of claim 1, wherein the concentrated population of cells comprising adipose-derived stem cells is grown in cell culture prior to being provided to the patient. 13. The method of claim 12, wherein said concentrated population of cells comprising adipose-derived stem cells is grown in culture conditions that promote differentiation towards a renal phenotype. 14. The method of claim 12, wherein said concentrated population of cells comprising adipose-derived stem cells is grown in culture conditions that promote differentiation towards an endothelial phenotype. 15. The method of claim 12, wherein the cell culture is performed on a scaffold that can be placed on or within the patient. 16. The method of claim 15, wherein the scaffold is resorbable in vivo. 17. A method for treating acute tubular necrosis (ATN) in a patient, comprising: identifying a patient with ATN; andproviding to the patient's renal parenchyma an amount of a concentrated population of cells comprising adipose-derived stem cells sufficient to restore blood flow to an ischemic region of the kidney of said patient. 18. The method of claim 17, wherein said patient is human. 19. The method of claim 17, wherein the concentrated population of cells comprising adipose-derived stem cells further comprises adipose-derived progenitor cells. 20. The method of claim 17, wherein the ATN is ischemic ATN. 21. The method of claim 17, wherein the ATN is nephrotoxic ATN. 22. The method of claim 17, wherein said concentrated population of cells comprising adipose-derived stem cells is provided to said patient in a bolus. 23. The method of claim 17, wherein said concentrated population of cells comprising adipose-derived stem cells is provided to said patient in multiple doses. 24. The method of claim 17, further comprising providing one or more additives to said patient or to said concentrated population of cells comprising adipose-derived stem cells. 25. The method of claim 17, wherein said concentrated population of cells comprising adipose-derived stem cells further comprises an additive. 26. The method of claim 24, wherein said additive is selected from the group consisting of a disaggregation agent, an immunosuppressive agent, and an angiogenic factor. 27. The method of claim 25, wherein said additive is selected from the group consisting of collagenase, trypsin, lipase, hyalurondiase, deoxyribonuclease, Liberase H1, a tissue or cell re-aggregation inhibitor, and pepsin, or any combination thereof. 28. The method of claim 18, wherein the concentrated population of cells comprising adipose-derived stem cells is grown in cell culture prior to being provided to the patient. 29. The method of claim 28, wherein said concentrated population of cells comprising adipose-derived stem cells is grown in culture conditions that promote differentiation towards a renal phenotype. 30. The method of claim 28, wherein said concentrated population of cells comprising adipose-derived stem cells is grown in culture conditions that promote differentiation towards an endothelial phenotype. 31. The method of claim 28, wherein the cell culture is performed on a scaffold that can be placed on or within the patient. 32. The method of claim 31, wherein the scaffold is resorbable in vivo. 33. A method for treating acute tubular necrosis (ATN) in a patient, comprising: identifying a patient with ATN; andcontacting the patient's kidney with an amount of a concentrated population of cells comprising adipose-derived stem cells sufficient to restore blood flow to an ischemic region of the kidney of said patient. 34. The method of claim 33, further comprising providing one or more additives to said patient or to said concentrated population of cells comprising adipose-derived stem cells. 35. The method of claim 33, wherein said concentrated population of cells comprising adipose-derived stem cells further comprises an additive. 36. The method of claim 34, wherein said additive is selected from the group consisting of a disaggregation agent, an immunosuppressive agent, and an angiogenic factor. 37. The method of claim 34, wherein said additive is selected from the group consisting of collagenase, trypsin, lipase, hyalurondiase, deoxyribonuclease, Liberase H1, a tissue or cell re-aggregation inhibitor, and pepsin, or any combination thereof. 38. The method of claim 33, wherein the concentrated population of cells comprising adipose-derived stem cells is grown in cell culture prior to being provided to the patient. 39. A method for treating acute tubular necrosis (ATN) in a patient, comprising: identifying a patient with ATN; andcontacting the patient's kidney with an amount of a concentrated population of cells comprising adipose-derived stem cells that is sufficient to increase blood flow to an ischemic region of the kidney said patient, wherein said concentrated population of cells is obtained in a self-contained adipose-derived stem cell processing unit, comprising:a tissue collecting container configured to receive and disaggregate adipose tissue, wherein said tissue collecting container is coupled to a cell collection container wherein said coupling defines a closed system in which disaggregated adipose tissue directed from tissue collecting container to cell collection container is not exposed to the external environment; and wherein said cell collection container, further comprises a centrifuge that facilitates separation of the cells in a suspension; andan outlet that is structured to permit concentrated stem cells to be aseptically removed from said self-contained adipose-derived stem cell processing unit. 40.
