Mechanosensitive Control of Articular Cartilage and Subchondral Bone Homeostasis in Mice Requires Osteocytic Transforming Growth Factor β Signaling

Objective Transforming growth factor β (TGFβ) signaling plays a complex tissue‐specific and nonlinear role in osteoarthritis (OA). This study was conducted to determine the osteocytic contributions of TGFβ signaling to OA. Methods To identify the role of osteocytic TGFβ signaling in joint homeostasis, we used 16‐week‐old male mice (n = 9–11 per group) and female mice (n = 7–11 per group) with an osteocyte‐intrinsic ablation of TGFβ receptor type...
