Reproducibility of the assessment of VD and VF in C6-pTET VEGF tumors
Control mice (n = 8; two slices/mouse) were imaged, and VD and VF maps were derived (t = 0). The mice were then given 5% sucrose in the drinking water without (n = 6; two slices/mouse) or with tetracyclin for the last 10 h (n = 2; two slices/mouse). No significant changes in VD or VF were observed under these conditions, in which there was no vascular damage (two-tailed unpaired t test). Some local effects were observed in VD maps at 10 h after the administration of tetracycline as shown in Fig. 1, n and p<$REFLINK> . | ||||||
