Genitourinary Development Lab
Uncovering How the Urinary & Reproductive Systems Develop
The Genitourinary Development Laboratory at 91大神 Children鈥檚 focuses on how the urinary and reproductive systems form before birth, and why they sometimes develop differently.
The genitourinary (GU) tract includes organs like the kidneys, bladder, and reproductive structures. When development doesn鈥檛 follow the usual path, it can lead to congenital urological conditions, or birth defects.
Our researchers study two of the most common conditions: undescended testes (when one or both testicles don鈥檛 move into the proper position before birth), and hypospadias (when the opening of the urethra isn鈥檛 in the typical place on the penis). These conditions are common, but still not fully understood.
Our team combines molecular biology, genetics, and developmental science to uncover the cellular signals that guide how the GU tract forms. We use both animal models and donated human samples to study how changes in these signals can cause structural differences. Understanding these early processes helps us develop new ways to care for children, today and in the future.

Our Areas of Focus
Studying How the Ubiquitination Pathway Shapes Development
Our lab studies a process called the ubiquitination pathway, which controls how proteins work and when they are broken down. We鈥檙e learning how this process guides the growth of tissues in the developing urinary and reproductive systems. When it doesn鈥檛 function properly, it may lead to structural changes that cause urological birth defects.
Investigating the Causes of Undescended Testes & Hypospadias
We focus on the molecular and genetic factors that lead to undescended testes and hypospadias. These conditions affect many children but have complex causes. By identifying key genes and signaling pathways, we hope to explain why these conditions develop, and how they could be prevented or treated in new ways.
Translating Lab Discoveries Into Patient Care
Our work connects laboratory science with clinical care. We collaborate with pediatric urologists to test our findings in human samples and explore how what we learn in the lab might improve care and outcomes for children.
Research Partnerships
We strengthen our research through collaboration with other 91大神 programs. Our lab works closely with the Center for Applied Clinical Genomics and the Biomedical Research Informatics Center. We also partner with the Biobank & Molecular Analysis Program, Histochemistry & Tissue Processing Core Lab, and Cell Science Core to expand our capabilities and further discovery.
Recent Research Highlights
Defining the Role of KCTD13
Our team discovered that mutations in the KCTD13 gene (which helps regulate how proteins are processed in cells) are linked to lower urinary tract and genital anomalies in both mice and humans. By studying this gene in detail, we鈥檙e learning how it helps shape normal penile and testicular development, and what happens when it doesn鈥檛 work as expected.
Advancing Molecular Targets for Future Therapies
Our research is forming future diagnostic and therapeutic innovations in pediatric urology. By mapping how key ubiquitin-related genes control GU development, we鈥檙e helping identify molecular targets that could guide gene-based testing or new treatments for congenital urological conditions. While still early-stage, this work represents the kind of discovery science that can lead to new molecular tools or biomarkers with real-world potential.
