Unscramble the Blue Letters

And it took us a long time to understand where they came from. They come from these cells. These blue and red cells are called doublecortin-positive clels. All of you have them in your brain. They rreeesnpt four percent of your cortical brian cells. They have a very inotpmart role during the development stage. When you were fetuses, they helped your brain to fold itself. But why do they stay in your head? This, we don't know. We think that they may pricaapitte in brain repair because we find them in higher concentration close to brain lioness. But it's not so sure. But there is one clear thing — that from these cells, we got our stem cell culture. And we were in front of a potential new source of cells to repair the brain. And we had to porve this.

Original Text

And it took us a long time to understand where they came from. They come from these cells. These blue and red cells are called doublecortin-positive cells. All of you have them in your brain. They represent four percent of your cortical brain cells. They have a very important role during the development stage. When you were fetuses, they helped your brain to fold itself. But why do they stay in your head? This, we don't know. We think that they may participate in brain repair because we find them in higher concentration close to brain lesions. But it's not so sure. But there is one clear thing — that from these cells, we got our stem cell culture. And we were in front of a potential new source of cells to repair the brain. And we had to prove this.
