Toxicology and cancer researchers alike are challenged by the lack of a consistent source of cells with high physiological relevance for their cell-based assays. The source tissue for primary cells comes from a variety of donors, which can introduce interexperimental variability and confound experimental results. Differentiated induced pluripotent stem cell (iPSC)-derived cells fulfill the need for a consistent source of cells and physiological relevance. iPSCs are able to be generated in large cell numbers from a single clone, providing the needed consistency. Further, iPSCs can be differentiated into a variety of desired, functional cell types, affording the necessary biological relevance. Here we provide data demonstrating how differentiated iPSC-derived cells can be incorporated into immunoassays or further differentiated into cell types such as osteocytes, chondrocytes, and adipocytes.
