A U.S. congressional subcommittee will hold a hearing next week on the stem cell scandal of disgraced scientist Hwang Woo-suk.

The counsel for the House Subcommittee on Criminal Justice, Drug Policy and Human Resources, Michelle Gress, said Thursday that the hearing will open Tuesday in Washington.

The panel will examine if Hwang's former collaborator Gerald Schatten used Hwang's faked cloning research to win a federal grant worth 16 million dollars and other funds.

Gress said the subcommittee did not ask Schatten to testify in next week's hearing, but his research will be discussed.

The National Institute of Health awarded the grant to Schatten in September last year for the launch of an ambitious stem cell program at the Magee-Women's Research Institute in Oakland.

A University of Pittsburgh professor, Schatten is the co-author of what had been hailed last year as a landmark paper published in the journal Science.

In the paper, Hwang's research team said it produced patient-specific stem cells from cloned human embryos. The breakthrough raised hope for developing cures for degenerative diseases like Alzheimer's or Parkinson's disease.

Science retracted the paper after it was ruled a fake in January by a Seoul National University investigative panel.
