Fig. 3From: Vascular abnormalities and development of hypoxia in microscopic melanoma xenograftsTumor growth and vascularization. a Intravital microscopy images of a representative microscopic A-07 window chamber tumor recorded 3, 5, 7 and 10 days after tumor initiation. The panels show fluorescence images of the GFP-expressing tumor cells (upper row) and transillumination images of the vasculature (lower row). Tumor area is delineated by a black line in the transillumination images. Scale bars, 1 mm. b Tumor area versus time for microscopic A-07, D-12, R-18, and U-25 window chamber tumors.
