Structure	Level	Pattern	Image	Note
TS17: embryo	Absent

Structure	Level	Pattern	Image	Note
TS19: pectoral-thoracic pre-cartilage condensation	Present	Regionally restricted	3A	Expression in cartilaginous ribs.
TS19: skeleton	Present	Regionally restricted	3A	Expression in the bony clavicle.

Structure	Level	Pattern	Image	Note
TS21: skeleton	Present	Regionally restricted	3B/C	Expression in periosteal cuff of bone forming the diaphysis. Expression principally in chondroblasts of mature zone of growth cartilage. Much lower levels of expression in chondroblasts than in osteoblasts.

Structure	Level	Pattern	Image	Note
TS22: rib cartilage condensation	Present	Regionally restricted	3E	Expression in osteoblasts of periosteal cuff of bone of rib cortex.

Structure	Level	Pattern	Image	Note
TS26: femur	Strong	Regionally restricted	3F/G	High levels of expression in periosteal derived osteoblasts of bony diaphysis, and in osteoblasts participating in endochondral ossification. No expression in hypertrophic and degenerative cartilage cells.

Structure	Level	Pattern	Image	Note
TS24: maxilla	Present	Regionally restricted	3H	Expression in the fine cancellous bone of maxilla. Expression persists in more mature osteoblasts. Most intense expression in preosteoblasts one or several cell layers from the osteoblasts of newly formed bones.
