Today concludes scientific sessions exploring how adipose tissue, or fat, can be an abundant source of stem cells that could be used for tissue engineering and regenerative medicine. An important outcome of the meeting was the development of a consensus defining key scientific questions for future study and determining the field's most promising clinical applications.
More than 300,000 liposuction procedures are performed in the United States each year, producing about 150,000 gallons of fat that is normally discarded. In 2001, researchers first reported that such tissue contained stem cells, and since then, additional studies have suggested they can be coaxed into other cell types, such as nerve, bone, muscle and blood vessels; or it may be that they have properties of these cells. Some research has progressed more rapidly, with animal studies indicating potential for the development of treatments for heart attack or bone injury, for example, while results looking at other uses are still quite preliminary.
There are currently no human trials in the United States evaluating the potential of stem cells derived from fat, but in reaching consensus on the most promising clinical applications, those attending the IFATS meeting believe the first clinical attempts in patients should be for repairing or healing bone defects, promoting growth of blood vessels in tissues not receiving sufficient blood supply, and for treating acute or chronic cardiac and peripheral vascular diseases.
Moreover, the group felt the
