Mouse brain tumor cells

A snapshot of a delicate web of tumor cells inside a mouse brain has won the top prize at this year’s Nikon Small World Photography Contest, which celebrates microscopy.
Dense, upright chains of a protein known as actin border each cell, and the cells contain a jumble of green tiny tubes called microtubules that surround a purple nucleus.
Bruno Cisterna Irazabal The researchers at Augusta University in Georgia who took this photo are studying whether disruption of structures around the nucleus may influence the development of neurodegenerative diseases such as Alzheimer’s disease.
“One of the main problems with neurodegenerative diseases is that their causes are not fully understood,” he said in a statement. “To develop effective treatments, we first need to understand the basics.”
