Imipramine Blue on Tumor Invasion (IMAGE) Georgia Institute of Technology Caption These images show that in vivo delivery of imipramine blue yields decreased invasion of the tumor into healthy tissue. On the left is an untreated tumor and on the right is a tumor treated with imipramine blue. To quantify cellular invasion beyond the tumor border (blue dotted line), researchers count the number of glioma cells (green) per area of healthy tissue (red).
