To review the intracellular signaling cascades and molecular mechanisms through which dexamethasone, ascorbic acid, and β-glycerophosphate drive osteogenic differentiation in bone marrow stromal stem cells.
Narrative synthesis of in vitro evidence detailing molecular pathways activated by the standard osteogenic cocktail (dexamethasone, ascorbic acid, and β-glycerophosphate).
Analysis of intracellular signaling networks, transcriptional regulators of osteogenesis, and the determinants separating physiological mineralization from dystrophic calcification.
Dexamethasone induces Runx2 transcription via FHL2/β-catenin activation and further enhances Runx2 transcriptional activity through upregulation of TAZ and MKP1.
Ascorbic acid promotes collagen type I secretion, stimulating downstream Col1/α2β1 integrin-mediated signaling.
β-Glycerophosphate acts as a phosphate donor for hydroxylapatite crystal formation while simultaneously modulating intracellular signaling pathways critical for bone-specific matrix mineralization.
