Evolution of mineralizing cells
in chondrichthyans

Meckel Rajidae
Meckel catshark

The endoskeleton of vertebrates is made of bone and cartilage. Chondrichthyans do not have bone but display mineralization patterns mostly on the cartilage surface.

The aim of this project is to characterize the mineralizing cell types in chondrichthyans and to infer their evolutionary history compared to bony vertebrates.

Methods: Histological sections & stainings

Working with: Mélanie Debiais-Thibaud, Faviel Alejandro López-Romero, and RHEM members
