Stem cells: When will they heal the heart?

Its been 15 years since a University of Wisconsin-Madison researcher isolated embryonic stem cells the do-anything cells that appear in early development. Its been six years since adult human cells were transformed into the related induced pluripotent stem cells.

Some day, stem cell therapy could restore cells, save hearts, and avoid the need for some heart transplants, such as this one. This heart is ready for its new home.

And yet the early hope to grow spare parts turning stem cells into specialized cells for repairing a failing brain, pancreas or heart, remains mostly promise rather than reality.

Researchers have since found how to transform stem cells into a wide variety of body cells, including heart muscle cells, or cardiomyocytes. But the holy Grail tissue supplementation or replacement remains tantalizingly out of reach.

Last week, Why Files attended a symposium on treating cardiovascular disease with stem cells, at the BioPharmaceutical Technology Center Institute near Madison, Wis. We found the picture unexpectedly complicated: as multiple kinds of stem cells are grown and delivered in a bewildering variety of ways to treat a catalog of conditions.

So far, stem cells have not been approved to treat any heart disease in the United States.

Still, the need remains clear. Disorders of the heart and blood vessels, which deliver oxygen and nutrients to the body, continue to kill. Today, one of every 2.6 Americans will die of some cause related to their heart, writes Columbia University Medical Center.
