Scientific imaging has made massive strides it what it is capable of showing us. We can watch the brain at work, see all the bones in our body and find that tumour that seemed to be invisible. Imaging can also give us some pretty cool pictures, so I put one behind my blog.
I got this image by typing 'Glial Cells' into Google and it is from the Encor Biotechnology website (their picture not mine!)
Glial cells make up most of the brain. While nerve cells carry the signals and do all the cool stuff, Glial cells provide them with the structure and nutrients for them to keep going, Fibroblasts are the main connective tissue in the body and are stained green. The star- shaped Astrocytes come out gold/orange. Astrocytes are pretty cool, they envelope the synapses in the brain and monitor their transmission. We don't really know much about them either, but it seems they might do more than just helping out the nerve cells. The blue dye reveals all the DNA in the nuclei of each cell.
Pretty picture hey? Shame i'm colour blind. I hate pictures.
