Docs: Adult stem cells can repair all tissues

Scientists involved in a study at Caritas St. Elizabeth's Medical Center have claimed that adult stem cells from bone marrow are capable of regenerating all types of tissue. If verified, these claims will remove a key, yet speculative, motivation for embryonic stem cell harvesting.

"The adult bone marrow contains cells that are capable of repairing the damaged heart," said Dr. Douglas Losordo, who helped lead the study at Caritas St. Elizabeth's Medical Center. After a heart attack, heart muscle is damaged, Losordo said yesterday. "We found that adult human bone marrow contains cells that are capable of differentiating into muscle cells and cells that form new blood vessels, which are the two principle things that are damaged during heart attack," Losordo said. - Boston Herald
Other researchers remain skeptical and assert that the only thing that has been objectively proven is that adult stem cells help heal a diseased heart (which is a key finding). [more here]
