Where can I purchase a human kidney fibroblast cell line?

The selection of the human kidney fibroblast model requires a quick judgement. Determine whether primary human kidney fibroblasts or immortalised fibroblast cell line is required for the experiment. Primary cells offer closer physiologically relevance with humans, but they have limited life span. However, with immortalized cells large scale experiments to gain reproducible data is possible.
To ensure consistency, reproducibility, and authenticity of the experimental outcome one must review the key features. This includes tissue origin, donor information, cellular morphology, passage number, culture medium, authentication, and mycoplasma testing. Globally, the suppliers of fibroblast and any animal cell culture related cells are procured from established repositories.
