  1. Fraction of segments that (1) showed no change in SHG signal of the adjacent cartilage matrix as a function of distance from the canal, (2) was surrounded by cells associated with intense SHG signal, (3) had presence of collagen fibres at the canal margin, (4) was surrounded by high TPEF signal in the surrounding cartilage matrix as an indication of calcification
