Our Translational Research Platform for Kidney Disease
SBH SCIENCESKidney Disease Research Center
We partner with industry and academic institutions to support drug development across a broad range of kidney disease indications by providing comprehensive disease modeling state-of-the-art functional assays, and biomarker discovery and development services.
Our In-Vitro Models, Biomarker Platforms, and Functional Assays
We have developed a platform of functional assays in a growing range of in vitro models to support drug development programs for key indications in renal disease drug development including:
- Diabetic Kidney Disease (DKD)
- IgA Nephropathy (IgAN)
- Focal Segmental Glomerulosclerosis (FSGS)
- Lupus Nephritis (LN)
- Autosomal Dominant Polycystic Kidney Disease (ADPKD)

Conditionally Immortalized Human Podocytes
- Cytoskeletal architecture and foot process analysis
- Podocyte survival and detachment
- Podocyte mitochondrial function and metabolic stress
- Slit diaphragm integrity
- Human podocytes disease-specific readout panel
Primary Human Proximal Tubule Epithelial Cells (hPTECs)
- Tubule injury and cytotoxicity
- Mitochondrial respiration and metabolism
- Fibrosis - TGF-β–driven fibrotic response
- Oxidative stress and Autophagy
- Tubular cell morphology
Human Primary Kidney Fibroblasts
- Myofibroblast activation
- Profibrotic signaling
- Kidney Inflammation
- Metabolic stress and mitochondrial injury
Established GLP Validation in Renal Biomakers
As part of its expanding kidney disease focus, SBH Sciences has already completed GLP validation of nine kidney-specific biomarkers. These assays have been optimized for precision, sensitivity, and reproducibility to support regulated development pathways.

Validation Parameters
- Precision
- Linearity (Accuracy)
- Sensitivity
- Reproducibility
- Stability
- Specificity (Cross Reactivity)
- Interference (Matrix Effect)
- Reference Range
