TGF-B's Role in Bone Growth
1. Mechanisms of Action
TGF-B signaling influences bone development through:
Stimulation of Mesenchymal Stem Cells (MSCs) → Drives osteoblast and chondrocyte differentiation.
Enhancement of Extracellular Matrix (ECM) Deposition → Boosts collagen, osteocalcin, and alkaline phosphatase activity.
Modulation of Growth Plate Chondrocytes → Supports longitudinal bone growth before epiphyseal closure.

2. TGF-B vs. BMP Signaling
While BMPs primarily drive osteoblast differentiation, TGF-B has a broader regulatory role:
Early-stage osteogenesis (MSC...
