01
Overview
Osteoblast differentiation signaling refers to the orchestrated network of signaling pathways that regulate the commitment, proliferation, and maturation of osteoblasts from mesenchymal stem cells. Canonical pathways include Wnt/β-catenin, BMP/Smad, TGF-β, Hedgehog, FGF, Notch, Hippo, MAPK (ERK, p38, JNK), NF-κB, and Ca2+ signaling, among others. These interconnected cascades regulate key osteogenic transcription factors (notably RUNX2 and Osterix) and mediate cellular responses necessary for bone formation, maintenance, and repair. Dysregulation of these pathways is implicated in various bone-related diseases, such as osteoporosis, bone fracture, osteolysis, and bone tumors[1][2][3][5][6].
