Figure 4. Changes in tumor oxygenation and blood volume.

Figure 4

Median pO2 values (A), percentage of hypoxic fraction (B), and mean blood volume (C) in the control and rapamycin treated SCC tumors. The values are average of 5 or 6 mice and error bars represent standard deviations. Oxygen delivery per unit blood volume (D) was calculated by dividing tumor pO2 by blood volume. * p<0.05 as compared with control, ** p<0.01 as compared with control, † p<0.05 as compared with rapamycin day 8, †† p<0.005 as compared with rapamycin day 8.
