<p>Disc shaped polymer/bioglass scaffold BG40, with a diameter of 5 mm and a thickness of 1 mm (A). A representative SEM image of BG40 is shown in (B). The composite demonstrates a relatively smooth surface with a thin fibrous texture and small pores (arrows). Scale bar indicates 6 µm. The release of ionic calcium to medium by BG40 (B4), BG20 (B2), PLA (P) and β-TCP (T) is shown in C. The most ionic calcium was released within the first two days. * = p<0.05 BG20, BG40 vs b-TCP, PLA; $ = p<0.05 BG40 vs BG20, n = 5.</p
