Verified step by step guidance

Understand the role of each cell type mentioned: Osteoblasts are responsible for bone formation, osteoclasts are involved in bone resorption, lacunae are small spaces containing bone cells, and chondrocytes are cells found in cartilage.

Recognize that the question is asking about cells that maintain mature compact bone, which implies a maintenance role rather than formation or resorption.

Recall that osteocytes are mature bone cells that originate from osteoblasts. Once osteoblasts become trapped in the matrix they secrete, they differentiate into osteocytes.

Osteocytes reside in lacunae and are connected by canaliculi, which allow them to exchange nutrients and waste with the blood supply, playing a crucial role in maintaining the bone matrix.

Conclude that osteocytes are the cells responsible for maintaining mature compact bone, as they regulate mineral content and communicate with other bone cells to ensure bone health and integrity.
