Using hiPSC-Derived Renal Proximal Tubular Cells in vitro assays to advance disease research and drug development
The rising numbers of kidney patients and a shortage of transplantable organs is a global health issue with high economic costs . Previous disease research and drug development has traditionally used animal models, but these fail to recapitulate human renal cellular function and so limit our ability to elucidate disease mechanisms and therapeutic targets.
Advances in stem cell biology over the last five years have transformed the state of play. Researchers are now able to access physiologically relevant renal cells and tissues derived from human induced pluripotent stem cells (hiPSCs), paving the way for therapeutic breakthroughs and novel applications.
One key application of human iPSC-derived renal proximal tubular cells (PTCs) is in safety toxicity testing during drug development . This is important because many pharmaceuticals can induce toxicity in the kidneys (nephrotoxicity), leading to impaired renal function and even death in the most severe cases. Now Axol have developed the first ready to use, commercially available hiPSC-derived Renal PTCs that have the potential to predict nephrotoxicity. This is providing researchers with access to high-quality, physiologically relevant renal cells for more efficient and reliable in vitro safety toxicity testing. Below we explore how hiPSC-derived Renal PTCs are not only advancing compound screening and drug development, but also have other exciting applications in kidney-related regenerative medicine, renal disease modelling, and the development of enhanced bioartificial kidneys.
