Probe:	Aggrecan cDNA2
Probe preparation:	Antisense labelled with digoxigenin RNA

Structure	Level	Pattern	Image	Note
TS22: mandible	Present	Regionally restricted	1d , 1b	Expression was detected adjacent to the ossifying mandibular bone anlage. Expression was also noted in the mesenchymal cell aggregation of the most posterior region.

Structure	Level	Pattern	Image	Note
TS23: mandible	Present	Regionally restricted	2d	Expression was detected in hypertrophic chondrocytes of the cartilage matrix.

Structure	Level	Pattern	Image	Note
TS24: mandible	Present	Regionally restricted	4b , 3d	Expression was detected from the fibrous cell layer to the bottom of the hypertrophic layer in the condylar cartilage of the mandible. This includes the polymorphic cell layer and the flattened cell layer.

Structure	Level	Pattern	Image	Note
TS26: mandible	Ambiguous		5e	Expression disappeared in the chondrocytes of the lower half of the hypertrophic cell layer of the condylar cartilage of the mandible.

Structure	Level	Pattern	Image	Note
TS21: tibia-fibula pre-cartilage condensation	Present	Regionally restricted	6d	Expression was detected in the chondrocytes.

Structure	Level	Pattern	Image	Note
TS22: tibia cartilage condensation	Present	Regionally restricted	6i	Expression was detected in the chondrocytes of the cartilage.
