Hyaline cartilage. Coloured scanning electron micrograph (SEM) of a freeze-fractured section through hyaline cartilage, a semi-rigid connective tissue. Chondrocyte cells (pink) in the cartilage synthesize an extracellular matrix (brown) that keeps them separate from each other, in spaces known as lacunae.
