There were no other medical options for Ho and he did it as a "last resort," Brown said.

He called the singer's heart condition, "extremely serious."

"It wouldn't hurt if the millions of his fans would start to pray for him," Brown said. "Don, as do I ... believe in the power of prayer."

The "VesCell" technology Ho underwent was developed by TheraVitae Co., which has offices in Thailand and laboratories in Israel, where Ho's stem cells were sent to be multiplied.

Dr. Robb MacLellan, associate professor of cardiology at UCLA, said a similar stem cell procedure has been used in Europe for a couple years and the U.S. Food and Drug Administration-approved studies are currently being conducted.

"The difficulty with any new therapy, no matter how promising it looks in animal models and even in small controlled human studies, we're never really sure if it's really safe or effective until rigorous controlled studies are done," he said.

Dr. Ralph Shohet, a molecular cardiologist at the University of Hawaii medical school, said there's a lot of excitement in the medical community surrounding stem cell therapy but the risks are not yet known.

"It's entirely an experimental procedure at present," he said.

Brown noted that Ho was not participating in controversial procedures involving embryonic stem cells.

"Don did not take stem cells from a fetus. He doesn't believe in that," he said. "He took blood from his own body and re-injected that into his heart."
