Naked Poly(amidoamine) Dendrimer Nanoparticles Exhibit Intrinsic Embryotoxicity During the Early Stages of Normal Development.
Journal of Biomedical Nanotechnology 2020 October 2
To investigate the impact of poly(amidoamine) dendrimers (PAMAMs) in the embryo, we explored the outcome of different generations (G₄ and G6 ) on the early stages of embryogenesis using the chicken embryo as a model. We also monitored their effect on angiogenesis in the chorioallantoic membrane (CAM). Our data revealed that cationic PAMAMs provoke substantial embryotoxicity, as they significantly induce death (up to 50%, p < 0 05) and inhibit angiogenesis of the CAM (up to 30%, p < 0 05) in a generation-dependent manner in comparison to controls and other types of PAMAMs (anionic and neutral). Moreover, cationic PAMAMs alter the expression of genes related to cell survival, cell cycle, proliferation, transcription factor, apoptosis, and angiogenesis, as shown by RT-PCR analysis. Our data suggest that PAMAM dendrimers exhibit intrinsic toxicity in embryos at the early stages and inhibits angiogenesis of the CAM. Thus, future studies are necessary to illustrate the exact mechanism of PAMAM dendrimers in embryotoxicity.
