Cell proliferation on HA surfaces in non-osteogenic culture.

<p>(A) WST-8 assay for MC3T3 cultured on HA-coated plates at day 1, 2 and 4. Blue and red lines denote untreated and plasma-treated groups, respectively. (B) DNA content of IP-CHA discs (<i>φ</i>5 mm × <i>h</i>2 mm) combined with rat MMCs. The MMCs/IP-CHA composites were cultured in non-osteogenic growth medium for 7 days. Data were represented as mean ± SD of 2 independent triplicate experiments.
