Adipose-derived regenerative cells for treating liver injury

Abstract

Cells present in processed lipoaspirate tissue are used to treat patients. 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. Compositions that are administered to a patient include a mixture of adipose tissue and stem cells so that the composition has a higher concentration of stem cells than when the adipose tissue was removed from the patient.

What is claimed is: 
     
         1 . A method of treating a patient comprising:
 (a) providing a tissue removal system;   (b) removing adipose tissue from a patient using the tissue removal system;   (c) processing at least a part of the adipose tissue to obtain a concentration of stem cells other than the concentration of stem cells of the adipose tissue before processing; and   (d) administering the stem cells to a patient without removing the stem cells from the tissue removal system before being administered to the patient.
