Fig. 5From: The initial engraftment of tumor cells is critical for the future growth pattern: a mathematical study based on simulations and animal experimentsBioluminescence signals from cultured tumor cells and initial tumors. The luciferin signal is depicted for different numbers of tumor cells (gray) and resected tumor nodules on days 1 (green), 2 (blue), 4 (violet) and 8 (purple) in photons per second per square centimeter per steradian (p/s/cm2/sr) in a and normalized to 105 cells in bBack to article page
