Figure 3From: The effect of novel nitrogen-rich plasma polymer coatings on the phenotypic profile of notochordal cells PTN 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 0 standard error of these five experiments. * p < 0.05 vs. PS control.Back to article page
