title: Radioautographic study of chondrocytic proliferation in nasal septal cartilage of the 5-day-old rat.
abstract: Relative rates of chondrocytic proliferation in the 5-day-old rat nasal septum are determined radioautographically, using tritiated thymidine as the labeling agent. The results are tabulated and charted graphically; they show that the zone of greatest activity is the portion just anterior to the septoethmoidal junction. The area of second highest activity is the antero-superior tip of the septum. All other regions are either relatively inactive or show only sporadic areas of proliferative activity.
