After admitting he had fabricated his groundbreaking paper in which he claimed to have created stem cell colonies from 11 patients, Seoul National University pledged to impose a heavy punishment on him, and said it was investigating his other claims, including his report of having cloned a dog and his announcement last year that he had achieved the first cloning of a human cell.
"I apologize to the South Korean people for creating an unspeakable shock and disappointment," Hwang said Friday.
However, the 53-year-old maintained that he had invented the technology needed to clone human embryos and to produce stem cells that genetically match patients, the New York Times said.
"Technology for patient-specific embryonic stem cells belongs to South Korea," Hwang said in his farewell. "And you will find out that this is true."
