What is lacunae in cartilage?

Lacunae in cartilage are small, hollow spaces or cavities within the cartilage matrix that house chondrocytes, the cells responsible for maintaining the cartilage. Each lacuna typically contains one or more chondrocytes, which are embedded in the surrounding extracellular matrix. These structures are crucial for the overall health and maintenance of cartilage, allowing for nutrient exchange and cellular communication. Lacunae help provide structural integrity and support to the cartilage tissue.
