Figure Lengend Snippet: Figure 5. In vivo role of NOGGIN in anterior floorplate size in the mouse embryo (A) Schematic of mouse crossing performed for inducible deletion of Noggin. E10.5 mouse showing the anatomy and section planes of the harvested and analyzed embryos. (B) Representative images of E10.5 control (NogFl/+;Sox2+/+ or NogFl/Fl;Sox2+/+) and Nog cKO (NogFl/Fl;Sox2CreERT2/+) embryos of mid/hindbrain (M/HB), cervical spinal cord (CSC), and thorax (THR) regions stained for DAPI (blue), FOXA2 (green), and SHH (magenta). Scale bars, 100 mm. (C) Normalized area of FOXA2 and SHH at different anterior-posterior levels of the embryonic NT. Quantification was made on serial sections of 6 control embryos (136 sections total, 33 for M/HB, 62 for CSC, 33 for THR) in purple and 3 Nog cKO embryos (68 sections total, 23 for M/HB, 30 for CSC, 15 for THR) in cyan from two litters. Kruskal-Wallis test and Dunn’s multiple comparison tests were performed between anatomical regions of control versus Nog cKO (FOXA2: M/HB versus M/HB p = 0.0165, CSC versus CSC p = 0.2706, THR versus THR p = 0.3926, SHH: M/HB versus M/HB p = 0.0031, CSC versus CSC p = 0.0792, THR versus THR p = 0.4484). Horizontal bars represent means of the data, asterisks indicate statistical significance, n.s. indicates non-significance.
