Role of planar cell polarity pathway in ameloblastoma with focus on frizzled 6
Putnová, Barbora ; Putnová, Iveta ; Hrubá, Eva ; Dosedělová, Hana ; Štembírek, Jan ; Daněk, Z. ; Buchtová, Marcela
Ameloblastoma is the most common epithelial odontogenic tumour in the oral cavity. Its progression is usually slow and the surface is covered by an oral mucosa with physiologic appearance. These tumours do not cause any pain to the patient and therefore it is difficult to diagnose them on time and the first signs are often missed by clinician leading to late diagnosis.
Mechanism of complex tooth shape development in reptiles
Landová, Marie ; Zahradníček, Oldřich ; Dosedělová, Hana ; Kavková, M. ; Zikmund, T. ; Buchtová, Marcela
Tooth shape formation in mammals is well known proces thanks to the broad studies on the mouse molars. The main role in regulation of this proces plays the enamel knot. Enamel knots are formed by cluster of cells, which serves as a source of numerous signalling molecules such as SHH or members of WNT, BMP and FGF families. Almost all our knowledge about teeth came from study on the mouse model. For better understanding of odontogenesis, it is however necessary to compare developmental processes to another species. One of the most heterogenic group of dentition type and shape are reptiles. How the shape of their teeth completed is still unknown. Aim of our study is therefore to uncover developmental processes involved in cusp formation in non-mammalian species with focus on reptiles. As model species for this study, we selected chameleons where multicuspis teeth develop in the caudal area of the jaw.
The effect of WNT5A and WNT7A on cartilage formation and anterior-posterior patterning of the limb
Killinger, Michael ; Buchtová, Marcela
Growth and patterning of the vertebrate limb is controlled by signals produced in the appical ectodermal ridge (AER) and by the zone of polarizing aktivity (ZPA). limb development requires tight interactions between these signalling centers to keep asymmetrical arrangement of all skeletal elements and their growth.
Role of FGF signaling in zeugopod development
Buchtová, Marcela ; Celá, Petra ; Horáková, D. ; Krejčí, P.
The fibroblast growth factor (FGF) signalling systém regulates many developmental processes including skeletogenesis, brain patterning, branching morphogenesis or limb development. as FGFs are key players in the variable processes of chondrogenesis, we experimentally manipulated this pathway to test its effect on zeugopode modeling.
