I apologize for creating this uproar both in and out of Korea. The fact remains that our research team was successful in creating stem cells from patients' skin cells. Still, there were mistakes made, human errors, in taking photographs and in the preservation of the stem cells.

After analyzing the data, our team concluded that the results . . . could not be trusted.

Our research team made patient-specific embryonic stem cells and we have the technology to produce them.

Technology for patient-specific embryonic stem cells belongs to South Korea. And you will find out that this is true.

I apologize to the people for creating an unspeakable shock and disappointment. I step down as professor of Seoul National University.

I would like to have time to confirm the validity of the technology.

There is no doubt that we produced 11 patient-specific stem cells and possess the core technology to create them again.

I respectfully ask legal authorities to launch an investigation as soon as possible. I am desperate to find out who switched the samples for what motive and how.

I sincerely apologize to the people for creating a shock and disappointment.
