NIH-funded research R01 grant

Spermatogonial stem cell transplantation and culture in patients

Funded at University of Pittsburgh at Pittsburgh · NIH-11645297 · Data updated 2026-11-12

Researchers are testing a way to transplant or grow sperm-producing cells back in boys and men who stored tissue before cancer treatment, to help them have biological children in the future.

Who could benefit from this research

Could help

Individuals who previously cryopreserved immature testicular tissue or spermatogonial cells and are eligible for autologous transplantation or tissue grafting.

Less likely to help

Patients without preserved tissue or those with contraindications for transplantation may not benefit.

What this research studies

This project explores transplanting human spermatogonial stem cells or grafting preserved testicular tissue back into patients to restore fertility after cancer therapy. It focuses on safety and feasibility of these approaches in people who previously cryopreserved tissue, with attention to potential cancer cell contamination and limited initial cell numbers. The work aims to translate promising lab methods into a clinical option that could help survivors have biological children. Participants would be men or boys who previously stored testicular tissue and are eligible for autologous transplantation ideas under the study protocol.

Why it matters

Potential benefit: If successful, this research could provide a new pathway for patients to regain fertility after cancer treatment.

How similar studies have gone: Prior lab and early clinical work supports the feasibility of SSC transplantation and tissue grafting, with ongoing translation to patients.
