Medial girdle muscles do not migrate using cMet. (A) Transverse cryosection through shoulder region of 15.0 dpc met-null embryo shows normal skeletal elements, scapula (s) and humerus (h), and the following muscles: trapezius (tr), serratus anterior (sa), rhomboidei (rh) and levator scapulae (ls). (B) Wild-type (wt) littermate shows the presence of normal scapular elements, medial girdle muscles and limb muscles demonstrating that neither the medial scapular border nor its medial girdle muscles require cMet/SF(HGF) for their development. Scale bar, 1 mm.
