Abstract
Summary
A histochemical study of calcium deposition in rat tracheal cartilage showed that deposition begins at about 2 weeks of age, and that by 6 weeks all the rings were involved. The deposition begins in the midventral area of the cephalad rings and extends caudally to all the rings, simultaneously extending posteriorly in each ring. It begins intracellularly and spreads to the matrix. The chondrocytes within these areas appear normal.
