Treatment of primary mouse osteoblasts with retinoic acid produces a homogeneous population of ramified cells bearing morphological and molecular features of osteocytes. The method overcomes the difficulty of obtaining and maintaining primary osteocytes in culture, and can be advantageous to study cells derived from transgenic...

This study outlines the method to visualize and develop three-dimensional (3D) models of osteocytes within the lacunar-canalicular network (LCN) for computational fluid dynamics (CFD) analysis. The generated models using this method help to understand osteocyte mechanosensation in healthy or diseased bones.

2026
Multiplexed immunofluorescence enables sequential labeling of multiple antibody markers within a single tissue section to support spatial analysis of tissue architecture and cell populations. Here, a workflow for multiplex detection of senescence-associated, structural, and immune markers is presented, including manual and automated slide preparation, iterative imaging, and single-cell analysis using digital pathology software.

A Lab-On-A-Chip Platform for Stimulating Osteocyte Mechanotransduction and Analyzing Functional Outcomes of Bone Remodeling

2020
Here, we present protocols for analyzing bone remodeling within a lab-on-a-chip platform. A 3D printed mechanical loading device can be paired with the platform to induce osteocyte mechanostransduction by deforming the cellular matrix. The platform can also be used to quantify bone remodeling functional outcomes from osteoclasts and osteoblasts (resorption/formation).
FAQs
Marker panels combine genes, proteins, and cellular features rather than relying on one signal. Expression of SOST, DMP1, PHEX, FGF23, and E11/gp38 can be interpreted alongside the cell's embedded location and dendritic morphology. This broader profile helps distinguish osteocytes from osteoblasts and other bone cells in tissue sections, cultured models, and single-cell analyses.
These markers reflect osteocyte differentiation and function, but the source material supports using them as a panel rather than treating any single gene as definitive. SOST, DMP1, PHEX, and FGF23 provide gene-expression signals, while E11/gp38 adds another marker signal. Together, these signals can support comparisons across bone-cell populations and experimental models.
Cellular morphology adds an important dimension to marker-based identification. Osteocytes develop dendritic processes within the lacunocanalicular network, so researchers can consider this feature together with molecular markers. The combined evidence is especially relevant when distinguishing mature osteocytes from other bone cells in tissue-based analyses.
The distinction is strongest when researchers evaluate multiple evidence types together. Osteocyte markers can be compared with features associated with osteoblasts and other bone cells, rather than interpreted in isolation. This approach is useful in tissue sections, cultured models, and single-cell analyses, where the available visual or molecular information may differ.
An analysis can begin by selecting a marker panel that includes genes, proteins, and cellular features. The panel can then be examined in tissue sections, cultured models, or single-cell analyses, depending on the research system. Comparing marker patterns with osteocyte morphology supports cell identification and enables consistent interpretation across experimental formats.
Osteocyte marker studies support investigations of skeletal development, mineral metabolism, mechanical sensing, and diseases in which osteocyte signaling alters bone formation or resorption. The same markers therefore connect cell identification with functional questions, helping researchers relate osteocyte state to broader biological changes in bone.
