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.

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

I feel so crushed and humiliated that I hardly have the energy to say I am sorry. I seek your forgiveness.

I sincerely apologize to the nation for using erroneous data in the papers.

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

We were crazy, crazy about our work. But I was blinded. All I could see was whether I could make Korea stand in the center of the world through this research.

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

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.

I feel so miserable it is difficult even to say sorry. I will be repenting for this for the rest of my life.

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

I take full responsibility for the papers and offer you my apology.

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

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

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...

As the lead author of the papers in which fake data appeared, I hold myself wholly responsible and I admit it and apologize.

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

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.

Mistakes [were] 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.

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

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

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

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...

When the use of these stem cells is limited to a particular country, it takes much too long to create technologies usable for the whole humanity. By creating a global network, we plan to share...

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