yah so they have this HEK cells I'm guessing and they subject them to fluids that were cooked in a microwave in a plastic container which thereby released a bunch of these nanoparticles. That fluid was applied to the HEK cells in vitro and they basically died and stoped dividing and migrating and doing all they would do. I suppose the connection would be lots of blood passes through the kidneys being a blood filtering tissue and what not that should nanoparticles enter the bloodstream they could take a toll on the kidneys. So if we were to be intravenously injected with these things it wouldn't be surprising to see stuff die I suppose. But the real world scenario never just dumps chemicals on certain tissues, they have to first reach those tissues and cross barriers and survive past the liver etc etc, lots of obstacles. But these in lab conditions kind of give a toxicity clue for what the outcome may be if the substance comes in direct contact with the tissue of interest.
