Some Current Research highlights
Osterix/SP knockout in Medaka does not prevent the formation of vertebral body anlagen (chordacentra).

No evidence that epethelial stem cells are involved in medaka tooth formation. Tan WH, Witten PE, Winkler C, Au DTW, Huysseune A (2017) Telomerase expression in medaka (Oryzias melastigma) pharyngeal teeth. Journal of Dental Research, 96(6) 678 –684
Severe phosphrous deficiency in Atlatic salmon does not disrupt bone formation.

The salmonid vertebral column has six distinct regions, one is a transitional region between abominal and caudal vertbral bodies.

Development, Plasticity and Remodeling of Skeletal Tissues
Our research focuses on development, plasticity, and remodeling of skeletal tissues; in particular bone, cartilage and teeth of teleost fish. Teleost fish are by far the largest and most diverse group of vertebrates on the planet. Processes are analyzed in a comparative developmental and evolutionary context. For anyone interested in evolution and development, the skeleton is the ideal organ system to study. Skeletal tissues are preserved in the fossil record and they can be analyzed in extant organisms. The group intensely studies the mechanisms underlying continuous tooth replacement in teleosts, we participate in biomedical research and we use our knowledge about fish skeletal tissues to prevent skeletal malformations in farmed fish.
The group has collaborations with Australia, Canada, France, Germany, Greece, Hon Kong, Italy, Spain, New Zealand, Norway, Portugal, Singapore, USA and the UK.
We organize the intentional conference “Interdisciplinary Approaches in Fish Skeletal Biology (IAFSB.org), follow the links at the tab “IAFSB conference”
