The numbers of anti-F4/80 antibody-positive macrophage-like cells in LLC-PlGF- and LLC-VEGF-induced tumor tissues derived from flt-1 TK (+/+) and flt-1 TK (−/−) micea

F4/80-positive macrophage-like cells(× 102/cm2)
LLC-PlGF8-day flt-1 TK (+/+)92 ± 56b
8-day flt-1 TK (−/−)108 ± 76
16-day flt-1 TK (+/+)40 ± 29
16-day flt-1 TK (−/−)11 ± 10
LLC-VEGF16-day flt-1 TK (+/+)50 ± 24
16-day flt-1 TK (−/−)48 ± 30
  • a The cells were counted at random in 10 fields for one tumor section. Three sections at 8 and 16 days were used for the analysis.

  • b Mean ± SD.
