Release of the mineralisation inhibitor, ATP, by osteoblasts and VSMCs. (A) Rank order of ATP release per cell was bone-forming osteoblasts > calcifying VSMCs > control VSMCs. Osteoblasts released 2.4-fold and 4.3-fold more ATP than calcifying and control VSMCs, respectively. (B) Basal ATP release was up to 85% higher in calcifying VSMCs compared to control VSMCs. Values are mean ± SEM (n = 12 replicate wells), *** = p < 0.001, * = p < 0.05.
