Immunostained images of OBs attached at Day 1 to (a) 0.8 wt% Si-HA, (b) 2.2 wt% Si-HA, (c) 4.9 wt% Si-HA and (d) HA. The nuclear DNA is stained blue, and the actin cytoskeleton is green. Images show enhanced OB proliferation on Si-HA with varying silicon content as compared with HA, and cells were well-oriented with a flattened cytoskeleton and distinct actin fibres [275].
