tbx6l and tbx16 have partially redundant roles in formation of tail paraxial mesoderm. A?R: In situ hybridization for ta (A?C), tbx6 (fss) (D?F), myoD (G?I), pax2a (J?L), fli1a (M?O), and lmo2 (P?R) at 24 hpf (A?C;G?R) and the 14- to 16-somite stage (D?F). Not shown are tbx6l single-mutant embryos as they are indistinguishable from wild-type embryos. In panel J, the row of pax2a-expressing pronephros cells is indicated by an asterisk (*), and the row of pax2a-expressing spinal cord neurons is indicated by a double asterisk (**). Scale bars in C (for A?C) and R (for G?R) = 100 ?m. Scale bar in F (for D?F) = 50 ?m.
