Infrared Nanoparticles Track Cancer Therapy
Tumor metastasis is associated with a physiological change in the tumor cells that gives them much greater mobility. A bone protein called BMP-7 is an important regulator of this physiological change. Researchers are studying the ability of BMP-7 to reverse the mobility of metastatic cells. In this image, researchers image the uptake of fluorescent nanoparticles (red) into kidney cell, whose nuclei are stained blue.
