The morphogenetic field concept was proposed by experimental embryologists to account for the self-regulative behavior of embryos. Such fields have remained an abstract concept until the recent identification of their molecular components using a combination of genetics, biochemistry, and theoretical modeling. One of the best studied models of a morphogenetic field is the Dorsal-Ventral (D-V) p...
In vertebrates and invertebrates, the bone morphogenetic protein (BMP) signaling pathway patterns cell fates along the dorsoventral (DV) axis. In vertebrates, BMP signaling specifies ventral cell fates, whereas restriction of BMP signaling by extracellular antagonists allows specification of dorsal fates. In misexpression assays, the conserved extracellular factor Twisted gastrulation (Tsg) is ...
Tsukushi Functions as an Organizer Inducer by Inhibition of BMP Activity in Cooperation with Chordin
STUDY DESIGN Quantitative gene expression analysis and immunohistochemistry were used to investigate the temporal and spatial expression of bone morphogenic proteins (BMPs) and BMP antagonists in a posterolateral spine fusion model in rabbits. OBJECTIVE To identify the expression pattern of BMPs and BMP antagonists and to determine the molecular and histologic changes of the graft and surroun...
