cSsp-AluI probe

Structure	Level	Pattern	Image	Note
TS20: sclerotome	Strong	Regionally restricted	4A	Expression was strong in the caudal halves of the lumbar sclerotomes, as well as in the centers of the sclerotomes.

Structure	Level	Pattern	Image	Note
TS20: sclerotome	Strong	Regionally restricted	4B	Signals were fused. There was an irregular array of elevated signals.

Structure	Level	Pattern	Image	Note
TS20: sclerotome	Present	Regionally restricted	4C	Signal was fused.

Structure	Level	Pattern	Image	Note
TS20: sclerotome	Present	Regionally restricted	4D	The ventromedial to dorsolateral extent of expression was normal. However, the three sclerotomes indicated display irregular and fused signals with altered rostrocaudal pattern. Strong signal in the rostral sclerotome halves, lateral to the negative spots. In the caudal sclerotome halves and ventromedially levels of expression are reduced.

Structure	Level	Pattern	Image	Note
TS17: sclerotome	Present	Regionally restricted	4E	Expression was highest in the caudal sclerotome halves.
TS17: spinal nerve	Absent		4E	Expression was negative in the spinal nerve in the lateral territory of the rostral sclerotome half.

Structure	Level	Pattern	Image	Note
TS17: sclerotome	Present	Regionally restricted	4F	Signals were fused. Lighter and darker staining appears at irregular intervals.

Structure	Level	Pattern	Image	Note
TS17: sclerotome	Present	Regionally restricted	4G	Signals were fused with ill-defined rostrocaudal pattern.

Structure	Level	Pattern	Image	Note
TS17: sclerotome	Present	Regionally restricted	4H	The rostrocaudal pattern of expression was altered. The ventromedial to dorsolateral extent was not changed. Sclerotomes exhibited fused signals and an erroneous pattern of up-regulation.
