몸 안을 투명하게 본다...생체조직 투명화 기술 개발
Korean scientists have developed a faster and more exact way of examining neurons and tissues, which could have implications for diagnostic medicine and brain mapping.
Lee Ji-won has more.
Korean scientists have found a way to see through an organ without damaging any tissues using a process for tissue clearing and labeling.
What you see here is the brain of an ordinary laboratory mouse on the left... and on the right is a brain that's gone through the process.
When the tissue is put into acrylamide, a compound used for making contact lenses,... and then heated, molecules connect with one another, creating a net.
Then, a surfactant is added and fat is melted out, leaving only cells and tissues behind.
Next, a dye is added to make the tissues easier to see.
The scientists were successful in completing the process for mice embryos, rabbit brains and webfoot octopi.
The development is an advance on previous tissue clearing techniques... and makes the process faster and allows for better visualization.
"Unlike the previous method, where we had to slice thousands of layers of tissue and put them together to see one neuron, this technology is a great advancement, as deep structures can be seen clearly and exactly, without any damage."
The technology is expected to not only improve the process of brain mapping, but could also expedite the results of diagnostic tests.
The study was published in the January issue of the international journal Scientific Reports.
