Figure 4. VEGF expression.

Figure 4

VEGF secretion in HEEC culture medium was determined by a human VEGF colorimetric ELISA kit. Supernatant samples were collected after 24 hrs of aPL (50 µg/ml) and tinzaparin (A) or enoxaparin (B) (0.1–1.0 IU/ml) treatment for VEGF measurement. Results are mean ± SE of four independent experiments and are expressed O.D. (Optical Density). CTR: untreated cells; T: tinzaparin; E: enoxaparin; O.D.: Optical Density; I.U.: International Units; ζ: P<0.05 compared with CTR; *: P<0.01 versus aPL treatment.
