David Rodrigues, PhD, ADME expert
"I have had a very positive experience working directly with the Newcells team using their aProximate complex in vitro kidney model in support of several drug transport projects. The model has been able to closely recapitulate human in vivo proximal tubule functionality and generated valuable insights regarding drug transport by primary human kidney cells. Of note, the aProximate model is the only one that can present elusive organic anion transporter (OAT1, OAT2, OAT3) functionality above and beyond the commonly reported organic cation transporter (e.g., OCT2, MATE1/2K) activity of other models. This has enabled careful characterization of the transporters (OCT2 versus OAT2) involved in the secretory renal clearance of creatinine, a widely used biomarker of renal function in clinical studies ( J Pharmacol Exp Ther. 2024 Jan 2;388(1):201-208). In my opinion, Newcells is the premiere provider of primary human renal cells with physiologically relevant functionality to support toxicity, renal clearance, and renal drug interaction screening."

Working with us
Timely service
Our ethical and secure primary tissue supply chain enables us to run studies and produce products to meet customers important and demanding timelines. We process multiple primary tissue every month meaning order-to-data response times can fit with the most demanding of customer deadlines.
Model validation
Our kidney tissue models are well-characterised and rigorously validated to ensure the generation of robust and comparable data predictive of in vivo renal physiology. Our clients also value our scientific expertise supporting the experimental design as well as the analysis and interpretation of data.
How we support our clients
By providing predictive data, we give our clients confidence in their key decision processes using our renal transporter models. Our service enables identification of cross-species differences in renal drug handling, identification of clinically relevant transporter-mediated Drug-Drug interactions and assessment of drug-induced kidney damage.
Our expertise
Our team have an in-depth knowledge of kidney physiology, cell-based models and assay development. They have designed and completed hundreds of studies on novel compounds using the unique renal models and provided interpreted data sets to customers to advance candidates into the clinic. Working under a QMS environment, the data and reports have been used to support regulatory submissions.
