Figure 2From: Identification of Phox2b-regulated genes by expression profiling of cranial motoneuron precursorsExpression patterns of a subset of genes up-regulated in ventral r4 of Phox2bLacZ/LacZembryos. (a-j) In situ hybridizations on transverse sections of ventral r4 of Phox2bLacZ/+(a, c, e, g, i) or Phox2bLacZ/LacZ(b, d, f, h, j) E10.5 mouse embryos. DIG-labeled riboprobes recognizing Igfbp5 (a, b), Hes1 (c, d), Sfrp1 (e, f), Tcf3 (g, h) and Sox13 (i, j) mRNA were used. (k, l) Immunofluorescence with an antibody recognizing Sox13 on transverse sections of ventral r4 of Phox2bLacZ/+(k) or Phox2bLacZ/LacZ(l) E10.5 mouse embryos.Back to article page
