stem cell treatment

Federal prosecutors in California and Florida sued on Wednesday to stop two companies from providing stem cell treatments, alleging the clinics marketed their procedures as remedies for ailments including cancer and heart disease without proof of safety and efficacy.

Florida has the second highest number of for-profit stem cell clinics in the United States, and a new proposal by a Tampa lawmaker would crack down on those that prey on elderly and vulnerable Floridians.


Three patients at a Florida clinic went blind after receiving eye injections of stem cells derived from their own abdominal fat, according to a report Thursday in The New England JournalĀ of Medicine.
