  sub:_5 prov:value "The expression of the hindbrain markers Krox20 and Epha4 was altered in Msx1/2 mutants, suggesting that defects in neural crest populations may result, in part, from defects in rhombomere identity. .. (Figure legend:) Note the reduction in the level of Krox20 transcripts in the caudal portion of r5 in mutant embryo at E8.5 (B,D), but normal expression at E9.5 (F). Epha4 expression was significantly increased in r1, r2 and r3 of the Msx1/2 mutant (arrowheads in P)." ;
