Novel insights into osteocyte and inter-organ/tissue crosstalk

Area of Science:

• Bone Biology
• Cellular Communication
• Physiology

Background:

• Osteocytes are bone cells embedded within the mineralized matrix.
• They possess numerous dendrites, forming a network for cell-to-cell communication.
• Osteocytes are increasingly recognized for their role in systemic homeostasis.

Purpose of the Study:

• To comprehensively review recent research on osteocyte crosstalk with vital organs.
• To discuss the bidirectional communication between osteocytes and organs like the brain, kidney, liver, and muscle.
• To explore the involvement of osteocytes in vascular calcification, adipose tissue function, and tumor metastasis.

Main Methods:

• Literature review of recent cross-sectional studies.
• Analysis of research on osteocyte extraction and culture techniques.
• Synthesis of findings on mechanical and biochemical communication pathways.

Main Results:

• Osteocyte communication extends beyond bone, influencing distant organs.
• Evidence suggests osteocytes play roles in vascular calcification and metabolic processes.
• The review highlights emerging understanding of osteocyte involvement in tumor metastasis.

Conclusions:

• Osteocytes are crucial regulators of systemic homeostasis through inter-organ communication.
• Understanding osteocyte-organ crosstalk opens new avenues for therapeutic interventions.
• Further research is needed to fully elucidate the complex roles of osteocytes in health and disease.
