specification and differentiation. Section in situ hybridization for
Scx (A,E,I,M,Q,U), Sox9 (B,F,J,N,R,V), and Sox5
(C,G,K,O,S,W). (D,H,L,P,T,X) Alcian Blue staining. (A-D) Alternate frontal

E10.5. (I-L) Alternate transverse sections through vertebrae at E11.5. (M-P)
Alternate transverse sections through ribs at E11.5. (Q-T) Alternate
transverse sections through vertebrae at E13.5. (U-X) Alternate transverse
sections through ribs at E13.5. My, myotome.
