I ask for your forgiveness. I feel so miserable that it's difficult even to say sorry.

I definitely have the source technology to produce tailored embryonic stem cells. I can replicate the process anytime.

The use of fake data ... is what I have to take full responsibility for as first author. I acknowledge all of that and apologize once again.

Dogs share physiological characteristics with humans. A lot of diseases that occur in dogs can be directly transferred to humans.

I truly find it difficult even to say I am apologetic (for the fabrication).

The researcher should have told me that he was not able to culture stem cells. I really don't know why he put Korea to shame and sent shockwaves worldwide.

The replacement took place under a detailed plan over quite a long period of time.

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

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

I sincerely apologize to the nation and the international community for using erroneous data in the papers. I was responsible for going over the data thoroughly, and if I had done so, we would have been able to avoid this huge crisis.
