Figure 2. Tumor blood vessels originate from the existing embryonic vasculature.

Figure 2

kdrl:NLS-KikGR embryos were photoconverted (green to red) immediately after B16 (non-fluorescent) tumor cell transplantation at 2 dpf. KikGR fluorescence was imaged at 2 dpi (4 dpf) in green (left) and red channels (middle). Right panel, merged image. All blood vessels in the tumor were positive for red and green expression. The number of embryos that have red positive cells over the total number of embryos is shown in lower right. Anterior is to the left, dorsal is up.
