Reconstructing the locomotion of extinct vertebrates offers insights into their palaeobiology and helps to conceptualize major transitions in vertebrate evolution. However, estimating the locomotor behaviour of a fossil species remains a challenge because ...
Otoliths are calcium carbonate components of the stato-acoustical organ responsible for hearing and maintenance of the body balance in teleost fish. During their formation, control over, e.g., morphology and carbonate polymorph is influenced by complex ins ...
The occurrence of chronic or delayed toxicity resulting from the exposure to sublethal chemical concentrations is an increasing concern in environmental risk assessment. The Fish Embryo Toxicity (FET) test with zebrafish provides a reliable prediction of a ...
We have engineered synthetic poly(ethylene glycol) (PEG)-based hydrogels as cell-ingrowth matrices for in situ bone regeneration. These networks contain a combination of pendant oligopeptide ligands for cell adhesion (RGDSP) and substrates for matrix metal ...
Polyalanine expansion in the human HOXD13 gene induces synpolydactyly (SPD), an inherited congenital limb malformation. A mouse model was isolated, which showed a spontaneous alanine expansion due to a 21-bp duplication at the corresponding place in the mo ...
Vertebrate limbs are an amazing example of successful adaptation to various environmental conditions. In higher vertebrates, forelimbs help to fly, swim, walk, dig or grasp, yet their basic structure (the sequence and spatial arrangement of bony elements) ...
Vertebrate limbs are an amazing example of successful adaptation to various environmental conditions. In higher vertebrates, forelimbs help to fly, swim, walk, dig, grasp or play the Passacaille, yet their basic structure (the sequence and spatial arrangem ...
Vertebrate gene members of the HoxD complex are essential for proper development of the appendicular skeletons. Inactivation of these genes induces severe alterations in the size and number of bony elements. Evx-2, a gene related to the Drosophila even-ski ...
Vertebrate Hox genes are required for the establishment of regional identities along body axes. This gene family is strongly conserved among vertebrates, even in bony fish which display less complex ranges of axial morphologies. We have analysed the struct ...
Synthetic hydrogels have been molecularly engineered to mimic the invasive characteristics of native provisional extracellular matrixes: a combination of integrin-binding sites and substrates for matrix metalloproteinases (MMP) was required to render the n ...
