Research has indicated that tumors thrive on nutrients carried to them by the blood stream.
The rapid growth of new blood vessels is a hallmark of cancer, and studies have shown that preventing blood vessel growth can keep tumors from growing, too.
To better understand the relationship between cancer and the vascular system, researchers would like to make detailed maps of the complete network of blood vessels in organs. Unfortunately, the current mapping process is time-consuming: using conventional methods, mapping a one-centimeter block of tissue can take months. In a paper published in the October issue of the Optical Society's (OSA
) open-access journal Biomedical Optics Express
, computational neuroscientists at Texas A&M University, along with collaborators at the University of Illinois and Kettering University, describe a new system, tested in mouse brain samples, that substantially reduces that time.
