Figure 2: expression of TNAP, and ectonucleotidases in metaphysis-containing bone fragments, hypertrophic chondrocytes and osteoblasts.
A: enzymes known to be involved in ATP hydrolysis into adenosine, and their inhibitor. B: RT-qPCR analysis of nucleotidase-encoding mRNA levels in the metaphysis-containing femurs and tibias of 7-day-old wildtype mice. Mouse primary chondrocytes (C, n=4 independent experiments) and primary osteoblasts (D, n=3) were cultured as detailed in the Materials and methods section and mRNA levels were quantified by RT-qPCR. * indicates a statistical difference with p<0.05; ** a difference with p<0.01; *** a difference with p<0.001.
