A former Medical University of South Carolina pathologist has pleaded guilty to causing the introduction of stem cells into interstate commerce without the approval of the U.S. Food and Drug Administration, according to the U.S. Department of Justice.

Vincent Dammai, 42, of Mount Pleasant entered his plea on Tuesday before U.S. Magistrate Judge Frances Stacey. Sentencing has been set for Nov. 14. Dammai faces up to a year in prison and a $10,000 fine, according to information posted at the website for the U.S. Attorney’s Office for the Southern District of Texas.

Dammai said he could not comment on the case because it involves an ongoing investigation. He referred questions to a website for his legal fund that says Dammai entered a guilty plea to mislabeling a biological material, a misdemeanor punishable by up to 12 months in jail and a fine of up to $10,000.

The government statement on Dammai’s guilty plea can be found at //www.justice.gov/usao/txs/. The legal fund website statement on Dammai’s guilty plea is at http://www.dammaimorganllc.com/donate--support.html.

A copy of the plea agreement was not immediately available.

Dammai was an assistant professor of pathology and laboratory medicine at MUSC. The university and Dammi reached an agreement not to renew his faculty contract. Dammai was on administrative leave until his contract expired in June, said Heather Woolwine, MUSC spokeswoman.

“MUSC has been kept abreast of the developments in this case by the authorities involved, and we’ve been commended for our cooperation,” Woolwine said.
