Probe:	M-twist cDNA1
Probe preparation:	Antisense labelled with S35 RNA
Visualized with:	Autoradiography

Structure	Level	Pattern	Image	Note
TS17: embryo	Present	Regionally restricted		M-twist was widely expressed in the mouse embryo at day 10.5 p.c., except in areas where myf5 is expressed.

Structure	Level	Pattern	Image	Note
TS17: trunk dermomyotome	Present		1A/B	M-twist is expressed in the dermatome, but not in the myotome.
TS17: trunk sclerotome	Present		1A/B

Structure	Level	Pattern	Image	Note
TS17: trunk dermomyotome	Present	Regionally restricted	1D/E	M-twist is expressed in the dermatome, but not in the myotome.
TS17: trunk sclerotome	Present		1D/E

Structure	Level	Pattern	Image	Note
TS17: forelimb bud	Strong	Regionally restricted	1G/H	M-twist is highly expressed in the developing limb buds but is not detectable in areas where myf5 is found.

Structure	Level	Pattern	Image	Note
TS20: embryo	Present	Regionally restricted		M-twist was widely expressed in the mouse embryo at day 12.5 p.c., except in areas where myf5 is expressed.

Structure	Level	Pattern	Image	Note
TS20: oral region	Present	Regionally restricted	2A/B	The expression domains of M-twist and myf5 are mutually exclusive in the developing branchial arches, where M-twist is not observed in the myf5-expressing anlagen of the jaw muscles.
