Morphology of joints and patterns of cartilage calcification in the endoskeleton of the batoid <i>Raja</i> cf. <i>polystigma</i> Open
The skeleton of the batoid fish consists of a mixture of calcified and uncalcified cartilage with a typical layout of mineral deposition toward the outer border, leaving an uncalcified central core in most of the skeleton segments. An exce…

New morphological evidence of the ‘fate’ of growth plate hypertrophic chondrocytes in the general context of endochondral ossification Open
The ‘fate’ of growth plate hypertrophic chondrocytes has been long debated with two opposing theories: cell apoptosis or survival with transformation into osteogenic cells. This study was carried out on the proximal tibial growth plate of …
