Global gene expression profiling and Western blot analysis revealed activation of several intra-cellular signaling pathways including focal adhesion kinase (FAK) and TGF\u03b2. Pharmacological inhibition of FAK using PF-573228 (5 \u03bcM) and TGF\u03b2 using SB505124 (1\u03bcM), diminished Apigenin- and Rutaecarpine-induced osteoblast differentiation.\n                      <jats:italic>In vitro<\/jats:italic>\n                      treatment with Apigenin and Rutaecarpine, of primary hBMSCs obtained from elderly female patients enhanced osteoblast differentiation compared with primary hBMSCs obtained from young female donors.\n                      <jats:italic>Ex-vivo<\/jats:italic>\n                      treatment with Apigenin and Rutaecarpine of organotypic embryonic chick-femur culture significantly increased bone volume and cortical thickness compared to control as estimated by \u03bcCT-scanning.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Discussion<\/jats:title>\n                    <jats:p>Our data revealed that Apigenin and Rutaecarpine enhance osteoblastic differentiation, bone formation, and reduce the age-related effects of hBMSCs.
