Article Title: Regulation of the Epithelial Adhesion Molecule CEACAM1 Is Important for Palate Formation
doi: 10.1371/journal.pone.0061653
Figure Lengend Snippet: At E15.5, palatal fusion was well under way in the wild-type embryo (+/+) (A, C, E, G). Ceacam1 −/− embryos (−/−) showed residual epithelial islands (B, D, F, H), similar to . Ceacam1 −/− MEE cells show positive Ki67 and TUNEL staining, markers for cell proliferation and apoptosis, respectively, from the anterior to the posterior part of the palate, and they express TGFβ3 at levels similar to the wild-type MEE cells. Expression levels were statistically analyzed (I, J, K); Ki67, 28.8±0.3 (+/+) (%), 30.6±2.4 (−/−) (%) (I); TUNEL, 5.0±1.4 (+/+) (%), 4.9±1.3 (−/−) (%) (J); TGFβ3, 86.9±3.7 (+/+) (%), 84.6±0.6 (−/−) (%) (K). Bars indicate s.e.m.; P = 0.52 (I), 0.50 (J), 0.50 (K), in Ceacam1 −/− palates compared to wild-type (+/+).
Article Snippet: Rabbit polyclonal antibody against TGFβ3 (Santa Cruz) or rabbit polyclonal anti-cytokeratin broad-spectrum screening antibody (Dako Cytomation) were used as the primary antibody, and goat anti-rabbit IgG (Alexa Fluor 488; Invitrogen Life Technologies), was used as the secondary antibody.
