Overview

In vitro study demonstrates that mechanical noise selectively alters osteocyte and osteoblast signaling under fluid shear stress, indicating distinct roles in bone mechanical adaptation.

Key Points

To investigate whether mechanical noise enhances the mechanosensitivity and signaling activity of MLO-Y4 osteocytes compared with MC3T3-E1 osteoblasts exposed to fluid shear stress.
Exposed cultured MLO-Y4 osteocytes and MC3T3-E1 osteoblasts in vitro to low-amplitude periodic fluid shear stress combined with varying noise intensities.
Quantified bone cell mechanosensory activation by measuring nitric oxide (NO) and prostaglandin E2 (PGE2) release, modeling responses via information content analysis.
Noise significantly amplified nitric oxide production in MLO-Y4 osteocytes subjected to low-amplitude periodic fluid shear stress, whereas MC3T3-E1 osteoblasts exhibited no noise-enhanced nitric oxide response.
MC3T3-E1 osteoblasts showed significantly increased prostaglandin E2 production in the presence of noise, while MLO-Y4 osteocytes demonstrated no enhancement over noise-only stimulation.
