MADISON, Wis. -

A CBS News eight-month investigation found a University of Wisconsin-educated doctor promised cures that science couldn't provide.

Dr. Dan Ecklund received his medical degree from UW in 1987, but his medical license was revoked in 2005, according to state records in Alabama. On Sunday night, "60 Minutes" accused Ecklund of peddling fake stem cell therapies to a family whose son has cerebral palsy, a disease with no known cure.

With so much research done on potential therapies and stem cells in Madison, local scientists are quick to distance themselves from Ecklund. Still, Dr. David Gamm, an ophthalmologist and stem cell researcher at UW, said similar attempts at fraud are all too common.

"With cord blood cells, the types of diseases and applications that (Ecklund) was discussing on '60 Minutes' is not possible," said Gamm. "I spend a good deal of my time trying to educate those patients and steering them away from those fraudulent purveyors."

Ecklunds' whereabouts since his interview are not known, according to "60 Minutes," but two men who purveyed ruse remedies in a prior report have been indicted on federal charges.

UW officials couldn't confirm that Ecklund was a graduate, but in his medical license records, Ecklund does claim he got his education in Wisconsin.

There is another Dr. Dan Ecklund in Wisconsin, who is licensed in La Crosse and has no connection to the" 60 Minutes" report or fraudulent stem cell claims.
