Scientists at the Stanley Manne Children’s Research Institute and Northwestern University have achieved a major breakthrough by successfully regenerating fully functional urinary bladder tissue in a long-term study using a non-human primate model. This groundbreaking research, led by the Sharma Research Group, opens up new possibilities for the treatment of severe bladder dysfunction.
The team utilized a unique approach, utilizing a biodegradable scaffold that was seeded with stem and progenitor cells derived from the primate’s own bone marrow. Remarkably, this method exhibited a higher success rate compared to the traditional use of intestinal segments for treating bladder dysfunction. Over a span of two years, the regenerated bladder tissue remained healthy and fully functional, providing a pre-clinical model that could be translated into human treatments.
Senior author Arun Sharma, Ph.D., expressed excitement about the results, stating that it “points to a new direction in the field” of bladder regeneration. Dr. Sharma, the Director of Pediatric Urological Regenerative Medicine at the Manne Research Institute, also anticipates the launch of a clinical trial in the near future, suggesting that this innovative platform could soon become a viable option for patients.
Bladder disease, particularly in severe cases, presents limited treatment options. Currently, small intestine tissue is commonly used for bladder augmentation surgery, but this approach carries with it various clinical complications. The aim of Dr. Sharma and his colleagues is to revolutionize this field by providing a safer and more effective alternative. By utilizing the patient’s own bone marrow cells, the risk of rejection is eliminated, and the biodegradable scaffold ensures a non-toxic solution.
This breakthrough has taken over a decade of dedicated research to achieve, and it holds immense potential for translation into clinical practice. The target population for this bladder regeneration work is pediatric patients with spina bifida. The success of this study could have a transformative impact on the lives of these children and other individuals suffering from end-stage bladder dysfunction. With the bladder demonstrating functionality within months, this advancement could pave the way for a revolution in clinical practice.

1. Stem cells: Cells that have the ability to develop into different types of cells in the body. In this study, stem cells derived from bone marrow were used.
2. Progenitor cells: Early cells that can differentiate into specialized cell types. They are more specific than stem cells but can still give rise to different cell types.
3. Biodegradable scaffold: A structure or support system that breaks down or dissolves over time, allowing the implanted cells to develop and grow.
4. Bladder dysfunction: Problems with the normal functioning of the bladder, such as difficulties in bladder emptying or bladder control.
5. Spina bifida: A birth defect in which the spinal cord does not develop properly, leading to various physical and neurological difficulties.
