The transport of mercury ions across intestinal epithelial cells can be studied for toxicology assessments by using animal models and static cell cultures. However, the concepts do not reliably replicate conditions of the ...
All multicellular organisms, including humans, animals and plants, are made up of specialized cells called differentiated cells. Thus, the cells that make up the epidermis do not have the same identity—nor the same function—as ...
