Clinicians and scientists are in need of a better understanding of cancer cells and their properties in order to provide targeted cancer treatment. Individual cancer cells are often examined in test tubes before the findings are tested in living organisms. "Our aim is to visualise cancer cells inside the living body to find out how they function, how they spread and how they react to new therapies," says medical physicist Professor Jan Laufer from MLU. He specialises in the field of photoacoustic imaging, a process that uses ultrasound waves generated by laser beams to produce high-resolution, three-dimensional images of the body's interior.
"The problem is that tumour cells are transparent. This makes it difficult to use optical methods to examine tumours in the body," explains Laufer whose research group has developed a new method to solve this problem: First the scientists introduce a specific gene into the genome of the cancer cells. "Once inside the cells, the gene produces a phytochrome protein, which originates from plants and bacteria. There it serves as a light sensor," Laufer continues. In the next step, the researchers...
