Figure 3From: Effects of osteoprotegerin from transfection of pcDNA3.1(+)/chOPG on bioactivity of chicken osteoclastsThe change of TRAP enzyme activity and concentration of Ca2+ in three groups. 3A: Effect of culture supernatant from chicken embryo fibroblasts transfected on osteoclastic TRAP enzyme activity (Mean ± SD; n = 8). ** indicates P < 0.01 compared with the control group. 3B: The concentration of Ca2+ in the supernatant containing bovine bone slices (Mean ± SD; n = 8). ** indicates P < 0.01 compared with the control group.Back to article page
