Figure 5From: The effect of novel nitrogen-rich plasma polymer coatings on the phenotypic profile of notochordal cells COMP expression in dog notochordal cells cultured on five different substrates. Dog notochordal cells were cultured for up to 14 days on PS control surface and four different PPE:N surfaces. GAPDH was used as housekeeping gene and served to normalize the results. Agarose gels are representative of 5 experiments. Quantitative results are the mean ± standard error of these five experiments. * p < 0.05 vs. PS control.Back to article page
