new paper: "E171-induced toxicity in human iPSC-derived colon organoids: Effects on cell viability, ROS generation, DNA damage, and gene expression changes" https://doi.org/10.1016/j.tiv.2025.106105

"Food-grade titanium dioxide (E171) is a widely used food additive with debated safety, particularly regarding its genotoxic effects. This study assessed the dose-dependent toxicity of E171 in human induced pluripotent stem cell (iPSC)-derived colon organoids."
