Article Title: Vascular endothelial growth factor overproduced by tumour cells acts predominantly as a potent angiogenic factor contributing to malignant progression

doi: 10.1046/j.1365-2613.1999.00122.x

Figure Lengend Snippet: (a) VEGF and (b) bFGF productivity of cancer cells transfected with VEGF cDNA. ▪ parental cells; □ transfected clones. The levels of VEGF and bFGF contained in conditioned medium and cell extract, respectively, were determined by sandwich ELISA. Sample values were plotted against a recombinant VEGF or bFGF standard curve (mean ± SE, n = 3). ND: not detectable. QG90, RPMI4788, MCF-7 and their transfected clones were cultured in RPMI1640 containing 10% FCS (normal). Hormones-stripped FCS with (E2+) or without (E2−) 10−8 M 17 β-oestradiol was used for MCF-7 and its transfected clone, M2–24-G10.

Figure Lengend Snippet: HUVE cell growth stimulatory activities in conditioned media of VEGF-transfected clones of (a) ○ QG90; □ Q1-1-C1; • Q1-24-E6; ▪ Q1-24-F6; ▴ Q1-24-H2, (b) ○ RPMI4788; • S0A12; ▪ S2G2 and (c) ○ MCF-7; • M2-24-D10; ▪ M2-24-E11; □ M2-24-G10 cells. HUVE cells were cultured in the presence of various concentrations of conditioned medium from each clone, indicated in Figure 1. After 4 days, HUVE cell growth was determined by MTT assay. The HUVE cell growth induced by 2.5 ng/ml of human recombinant VEGF165 was used as a positive control (♦). Results are presented as the percentage of the control without any growth factor. Each point indicates the mean of duplicate determinations.

Figure Lengend Snippet: In vivo angiogenic activity of VEGF-transfected clones of (a) QG90 and (b) RPMI4788 cells. A Millipore chamber containing each clone or HBSS was implanted s.c. into a dorsal air sac of a BALB/c mouse (three to six mice/group). After 4 days, the area of new capillarization induced by each clone was determined with an image analyser. Results (mean ± SE) are presented as percentages of the mean area of the control group treated with a HBSS-containing chamber. * P < 0.01 vs. the control group; ns, not significant (by Student's t-test).

Figure Lengend Snippet: Hematoxylin and eosin-stained sections of tumours 32 days after s.c. injection of (a) RPMI4788 cells and the transfected clones, (b) S0A12 and (c) S2G2 cells into nude mice. RPMI4788 cells yielded small, poorly vascularlized tumours (a), whereas both clones yielded well-vascularlized ones (b, c). Arrow heads indicate blood vessels. Scale bar = 400μm.
