Growth factors and matrix metalloproteinases released by CGF-coated implants. Implants permeated with CGF were incubated in cell culture medium for a period of 0–28 days. At the indicated times (1, 7, 14, 21, and 28 days), the conditioned media were collected. The growth factors (A) VEGF, (B) TGF-β1, (C) BMP-2, the matrix metalloproteinases (D) MMP-9, and (E) MMP-2 were quantified by ELISA. The results are expressed as the means ± SD of triplicate measurements from three independent experiments.
