On the Cover: Image of extracellular matrix surrounding normal chondrocytes was captured and modeled as wire-frame renditions. Proteins shown include type II collagen (yellow), type IX collagen (red), cartilage oligomeric matrix protein (COMP; green) and matrilin 3 (blue). These interactions are altered by mutant COMP in pseudoachondroplasia and multiple epiphyseal dysplasia. (see page 293)
