Structure	Level	Pattern	Image	Note
TS21: tail mesenchyme	Present		3C
TS21: tail spinal cord	Present		3C
TS21: spinal cord	Present	Regionally restricted	3C	Expression is in the spinal cord posterior to the hindlimb bud. The anterior expression boundary is at the level of L2/L3.
TS21: trunk mesenchyme	Present	Regionally restricted	3C	Expression is in the mesoderm posterior to the hindlimb bud. The anterior expression boundary is located more posteriorly than the expression in the spinal cord.
