New Rochelle, NY, December 10, 2018—A team of researchers developed a novel model of partial bladder outlet obstruction (pBOO) in female swine and used this model to show that even after inducing severe urinary outlet resistance and damage to the bladder, they could achieve significant improvements in bladder capacity through bladder reconstruction using acellular bi-layer silk fibroin (BLSF) grafts. The BLSF matrices supported the growth of new tissue with contractile properties, as described in a study published in Tissue Engineering, Part A, peer-reviewed journal from Mary Ann Liebert, Inc., publishers.

The article entitled “Augmentation Cystoplasty of Diseased Porcine Bladders with Bi-layer Silk Fibroin Grafts” was coauthored by Joshua Mauney, PhD, Boston Children’s Hospital and Harvard Medical School, Boston, MA, and a team of researchers from those institutions and Veterans Affairs Boston Healthcare System, West Roxbury, MA, Brigham and Women’s Hospital, Boston, and The University of Massachusetts, Boston.

The severe pBOO swine had a 61% decline in bladder compliance compared to the start of the study. By 3 months after the tissue engineering/reconstruction, bladder capacity and compliance had increased significantly (79+19% and 171+75%), compared to baseline values, respectively. The BLSF scaffolds were made from aqueous silk fibroin solutions derived from Bombyx mori silkworm cocoons.

“Robust preclinical research models can be as important as the development of tissue engineered therapies themselves in making these technologies a clinical reality,” says Tissue Engineering Co-Editor-in-Chief Antonios G. Mikos, PhD, Louis Calder Professor at Rice University, Houston, TX. “The disease model and bi-layer silk fibroin grafts presented in this article may enable a quicker, more effective clinical pathway to treating partial bladder outlet obstruction.”
