    AnnotationRugae palatinae (RP) -transversal mucosal ridges of the mammalian palate - are assumed to play role during closure of the palate in embryos. The aim of this study was to assess the morphogenesis of palatal ridges in the golden hamster by light and scanning electron microscopy. Cell proliferation was detected by immunohistochemical staining of proliferation cell nuclear antigen (PCNA). In the hamster, three to four antemolar and three intermolar ridges were formed. In ED 11.0 (ED-embryonic day) embryos, RP1 and RP3 were at the epithelial thickening stage, RP2 was a primitive ruga in the rostral part of the palatal processes. In the caudal part of the palate, an epithelial placode represented the prospective RP4-RP7. At ED 12.5, the closed secondary palate bore six ridge primordia. Only RP2 protruded distinctly into the oral cavity. At ED 13.0-14,5 and ED 15,0-15,5, the mesenchymal core of the antemolar and intermolar ridge primordia, respectively, started to develop.
