Article Title: Focal Adhesion Kinase Plays a Role in Osteoblast Mechanotransduction In Vitro but Does Not Affect Load-Induced Bone Formation In Vivo
doi: 10.1371/journal.pone.0043291
Figure Lengend Snippet: (A) Fold-change in PGE 2 release in FAK+/+ and FAK−/− osteoblasts following 2 hours of oscillatory flow and a 4 hour post-flow incubation. FAK−/− osteoblasts exhibited a significantly lower fold-change in PGE 2 release in response to fluid flow compared to FAK+/+ osteoblasts. (B) Fold-change in PGE2 release following fluid flow in mutant osteoblasts transiently re-expressing wild-type focal adhesion kinase and phosphospecific site mutations. Note that differences in absolute fold-changes in PGE2 release following flow in Panel A and Panel B represent variations in parallel assays.
