Decreased vascular density in LLC tumors when grown in COX-2–/– mice. (a) Representative photomicrographs of factor VIII–stained tumor sections from LLC tumors grown in wild-type (+/+) or Ptgs2–/– (–/–) mice (×200). (b) Factor VIII–positive vessel counts obtained by morphometric analysis of LLC tumors. Values represent the average number of vessels at ×200 ± the SD (Student’s t test; P = 0.04). HPF, high power field.
