(A) VEGF secretion by CCD-18Co fibroblasts cultured on different amounts of 45S5 BG coating for 3 d. (B) Decreased number of metabolically active fibroblasts in cells cultured on surfaces coated with 45S5 BG. (C) Cells and 45S5 BG particles were uniformly distributed in the alginate microspheres. High-density glass particles at 1% (w/v) cause the beads to become opaque. (D) The higher concentration of glass (1%) resulted in less VEGF secretion. Adapted from [85].
