Structure	Level	Pattern	Image	Note
TS21: face mesenchyme	Strong	Regionally restricted	3B	Increased expression in cranio-facial mesenchyme.
TS21: vertebral cartilage condensation	Present	Regionally restricted	3B	In developing vertebra, expression began decreasing in rostral-to-caudal fashion, reflecting degree of differentiation of chondrogenic cells.
TS21: vertebral pre-cartilage condensation	Present	Regionally restricted	3B	In developing vertebra, expression began decreasing in rostral-to-caudal fashion, reflecting degree of differentiation of chondrogenic cells.
