Sea urchin embryos are highly sensitive to several kinds of stressors, and able to activate different defense strategies. Gadolinium (Gd) is a metal of the lanthanide series of the elements: its chelates are employed as contrast agents for magnetic resonance imaging since the 1980s. Gd complexes are released in the aquatic environment, making Gd an emergent environmental pollutant. In this study we focused on the effects of Gd ions on sea urchin embryos development. The study was conducted looking at three different processes: general development, apoptosis and autophagy. At the whole morphological level, Paracentrotus lividus sea urchin embryos continuously exposed to Gd ions displayed mor…
