The mission of the Humphreys Lab is to understand the cellular and molecular mechanisms of kidney regeneration and thereby identify new therapeutic strategies for humans suffering from kidney disease. A primary focus is on stem cell-based therapeutic approaches. We use mouse as a model system as well as human pluripotent stem cells. The work encompasses two main areas:
- Developing stem cell-based approaches to treat kidney disease in humans.
- Understanding the mechanisms of kidney repair and recovery after injury.
