Vücudun İçinde Hareket Eden Bir

Hücrenin İlk HD İzi Görüntülendi

Eğer çoğu insan gibiyseniz, gördüğünüz ilk biyolojik hücre görselleri ders kitaplarındaki
bir şema yada mikroskop görüntüsü. Bilim adamları içinde benzer durumlar geçerli.
Oldukça küçük hücreleri yakınlaştırmak zordur, hücrelerin 3D görüntüsünü yakalamak
çok daha zordur. Araştırmacılar, vücutta görevlerini yerine getiren hücrelerin 3D
görüntülemelerini sağlayan bir görüntüleme cihazı geliştirdiler.

Watch the First-Ever HD Footage
of a Cell Moving Through the Body

If you’re like most people, the first biological cell you ever saw was flat: a diagram in a book, or maybe
a microscope image on a slide if you were lucky. Same goes for scientists. It’s hard enough to zoom
in on something so small, much less capture a 3D image of the thing. As a result, it’s easy to ima-
gine that there is a multitude of two-dimensional discs filling your blood vessels and fighting your
infections. That’s why this new development is so eye-opening. Researchers have made an ima-
ging breakthrough that lets them capture 3D footage of cells doing their thing inside the body —
and it may look nothing like what you imagined.
So Betzig and his team took a page from their book, combining adaptive optics with a technology
called lattice light sheet microscopy. This imaging technique sweeps an ultra-thin sheet of light
through the cell, building a high-resolution 3D movie from the 2D images it takes in real time. They
aimed one adaptive optical system at the side view to maintain the lattice light sheet’s illumina-
tion and aimed another adaptive system from above. Then, they could shine their reference laser
through either pathway to let the optics self-correct and achieve a super-sharp 3D image.
