Osteoclast

Meaning

An Osteoclast is a large, multinucleated cell derived from the hematopoietic lineage responsible for bone resorption, meaning it actively breaks down and remodels existing bone matrix. This process is vital for releasing stored minerals and reshaping bone structure in response to mechanical load and hormonal cues. Clinically, excessive osteoclast activity is implicated in conditions leading to bone density loss. We must understand their activity to preserve skeletal integrity.
