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.
