Research

Human kidney organoids as a platform for development, disease, and therapeutic discovery.

The lab's work centers on directed differentiation of pluripotent stem cells into nephron-like structures, then using those tissues to model kidney development, injury, genetic disease, organoid-on-chip physiology, and translational applications.

Directed differentiation

The 2015 Nature Biotechnology study described a protocol for deriving nephron organoids from human pluripotent stem cells and using them to model kidney development and injury.

  • Pluripotent stem cells are guided through developmental stages toward kidney lineages.
  • Organoids form epithelial nephron-like structures with podocyte and tubular markers.
  • The platform supports mechanistic studies of nephrotoxicity and kidney injury.

Kidney development

Modeling how human nephron structures form from progenitor states.

Disease and injury

Studying epithelial injury, repair, nephrotoxicity, and genetic kidney disease mechanisms.

Functional maturation

Combining organoids with imaging, transport assays, flow systems, and bioengineering strategies.

Automation and scale

Developing bioreactor-scale culture and automation workflows to improve maturation and batch consistency.

Regenerative medicine

Exploring how engineered kidney tissues might support future therapeutic development.

Translational applications

Human models for discovery, safety, and disease mechanism studies

Disease mechanism studies

Human organoid systems can help investigate mechanisms of kidney injury, repair, fibrosis, and inherited disease.

Kidney safety assessment

Human-relevant organoid platforms can support kidney safety studies for candidate therapies and perturbations.

Gene therapy response modeling

Kidney organoid models can help explore AAV-associated kidney responses and related safety questions.

AI-assisted phenotyping

Three-dimensional imaging and quantitative analysis support high-content therapeutic discovery workflows.

From cells to structured tissue

For a patient or donor audience, the important message is simple: the lab creates human kidney-like tissues in the dish so that disease and treatment questions can be studied in a more human-relevant system.

For a scientific audience, the same platform offers controllable differentiation, marker-based quality assessment, microscopy-based phenotyping, and compatibility with engineered culture systems.

Human-relevant models are becoming a regulatory priority

FDA and NIH public materials describe a shift toward New Approach Methodologies, including organoids, organ-on-chip systems, computational modeling, and other human-relevant approaches that can reduce, replace, or refine animal testing. This does not mean animal studies are obsolete in every setting, but it strengthens the rationale for kidney organoid and microphysiological platforms.
