Methods of treating patients for conditions such as breast augmentation, soft tissue defects, and urinary incontinence, are described. The methods include removing adipose tissue from a patient, processing a portion of the adipose tissue to obtain a substantially isolated population of cells comprising disaggregated adipose-derived stem cells, mixing the concentrated population of adipose-derived cells comprising disaggregated adipose-derived cells with a portion of unprocessed, intact, non-disaggregated adipose tissue to form a composition, and administering the composition to the patient from which the adipose tissue was removed.

1. A method of augmenting autologous fat transfer to a subject, comprising: removing a first portion of adipose tissue that comprises a cell population comprising adipose-derived stem cells from said subject;introducing the removed adipose tissue into a self-contained cell processing unit configured
1. A method of augmenting autologous fat transfer to a subject, comprising: removing a first portion of adipose tissue that comprises a cell population comprising adipose-derived stem cells from said subject;introducing the removed adipose tissue into a self-contained cell processing unit configured to maintain a closed pathway;isolating said cell population that comprises adipose-derived stem cells from mature adipocytes and connective tissue present in the removed adipose tissue so as to obtain a substantially isolated cell population comprising disaggregated adipose-derived stem cells, while maintaining a closed pathway;concentrating said substantially isolated cell population comprising disaggregated adipose-derived stem cells so as to obtain a concentrated cell population that comprises disaggregated adipose-derived stem cells, while maintaining a closed pathway;mixing said concentrated cell population comprising adipose-derived stem cells with a second portion of unprocessed adipose tissue comprising intact, non-disaggregated tissue fragments obtained from said subject, so as to obtain an adipose tissue composition comprising a mixture of said concentrated cell population comprising disaggregated adipose-derived stem cells and said unprocessed adipose tissue comprising intact, non-disaggregated tissue fragments tissue; andreintroducing said adipose tissue composition into said subject. 2. The method of claim 1, further comprising providing said mixture of the unprocessed adipose tissue comprising intact, non-disaggregated tissue fragments and the concentrated cell population that comprises disaggregated adipose-derived stem cells to a breast of the subject. 3. The method of claim 1, further comprising providing said mixture of the unprocessed adipose tissue comprising intact, non-disaggregated tissue fragments and the concentrated cell population that comprises disaggregated adipose-derived stem cells to a soft-tissue region of the subject. 4. The method of claim 1, further comprising providing said mixture of the unprocessed adipose tissue comprising intact, non-disaggregated tissue fragments and the concentrated cell population that comprises disaggregated adipose-derived stem cells to a urethral region of the subject. 5. The method of claim 1, wherein the concentrated cell population that comprises disaggregated adipose-derived stem cells further comprises progenitor cells. 6. The method of claim 1, multiple doses of the mixture of the unprocessed adipose-tissue and the concentrated cell population that comprises disaggregated adipose-derived stem cells is provided to said subject. 7. The method of claim 1, further comprising providing an additive to the concentrated cell population that comprises disaggregated adipose-derived stem cells. 8. The method of claim 1, further comprising providing an additive to the mixture of the unprocessed adipose tissue comprising intact, non-disaggregated tissue fragments and the concentrated cell population that comprises disaggregated adipose-derived stem cells. 9. The method of claim 1, further comprising providing one or more angiogenic factors to the mixture of the unprocessed adipose-tissue and the concentrated cell population that comprises adipose-derived stem cells. 10. The method of claim 1, further comprising providing the one or more arteriogenic factors to the mixture of the unprocessed adipose tissue comprising intact, non-disaggregated tissue fragments and the concentrated cell population that comprises disaggregated adipose-derived stem cells. 11. The method of claim 1, further comprising providing one or more immunosuppressive drugs to the mixture of the unprocessed adipose tissue comprising intact, non-disaggregated tissue fragments and the concentrated cell population that comprises disaggregated adipose-derived stem cells. 12. The method of claim 1, further comprising culturing said concentrated cell population that comprises disaggregated adipose-derived stem cells prior to mixing said concentrated cell population that comprises disaggregated adipose-derived stem cells with said second portion of unprocessed adipose tissue comprising intact, non disaggregated tissue fragments from said subject. 13. The method of claim 12, wherein said culturing step comprises exposing said concentrated cell population that comprises disaggregated adipose-derived stem cells to culture conditions that promote differentiation towards an endothelial phenotype. 14. The method of claim 12, wherein said culturing step is performed on a scaffold. 15. The method of claim 14, wherein said scaffold is resorbable in vivo. 16. The method of claim 1, wherein the mixture of the unprocessed adipose tissue comprising intact, non-disaggregated tissue fragments and the concentrated cell population that comprises disaggregated adipose-derived stem cells promotes neovascularization. 17. The method of claim 16, wherein the neovascularization remains stable after the administered adipose-tissue composition is no longer present. 18. The method of claim 1, wherein the mixture of the unprocessed adipose tissue comprising intact, non-disaggregated tissue fragments and the concentrated cell population that comprises disaggregated adipose-derived stem cells reduces necrosis. 19. The method of claim 1, wherein the subject is human. 20. The method of claim 1, wherein the concentrating step is done in a centrifuge. 21. The method of claim 1, wherein the self-contained cell processing unit comprises a centrifuge disposed therein. 22. The method of claim 1, wherein said mixture of the unprocessed adipose tissue comprising intact, non-disaggregated tissue fragments and the concentrated cell population that comprises disaggregated adipose-derived stem cells is provided to said subject while maintaining the closed pathway. 23. The method of claim 1, wherein said mixing step is performed while maintaining the closed pathway.
