Patent has potential for applications beyond diabetes, including other cell and tissue transplantation procedures
HOUSTON, Aug. 11, 2026 /PRNewswire/ -- FibroBiologics, Inc. (Nasdaq: FBLG) ("FibroBiologics"), a clinical-stage biotechnology company with 270+ patents issued and pending with a focus on the development of therapeutics and potential cures for chronic diseases using fibroblasts and fibroblast-derived materials, today announced that the United States Patent and Trademark Office (USPTO) has issued U.S. Patent No. 12,691,147, entitled "Methods and Compositions for Treatment of Type 1 Diabetes Using Fibroblasts in Facilitation of Islet Engraftment." The patent describes methods utilizing fibroblasts to improve the engraftment and long-term function of transplanted pancreatic islets, addressing one of the major challenges in islet transplantation.
Type 1 diabetes affects millions of people and is caused by autoimmune destruction of the insulin-producing beta cells of the pancreas. Transplantation of pancreatic islets remains the only established cell-based approach capable of restoring endogenous insulin production and, in some patients, achieving insulin independence. Adoption has been limited by a severe shortage of donor pancreases and the loss of transplanted islets due to poor engraftment.
The newly issued patent addresses the challenge by describing the use of fibroblasts to improve the microenvironment for transplanted islets. The patented methods encompass compositions and therapeutic approaches designed to increase islet viability following transplantation. Fibroblasts are known to produce extracellular matrix proteins, angiogenic factors, and trophic signals that may improve vascularization, reduce cell stress, and enhance survival of transplanted tissues.
"One of the greatest limitations facing islet transplantation is that many transplanted islets fail to survive the critical period immediately after implantation," said Pete O'Heeron, Founder and Chief Executive Officer of FibroBiologics. "If we can improve engraftment, each donor pancreas could potentially benefit more patients. Technologies that preserve transplanted islets may ultimately help expand access to curative therapies for patients living with Type 1 diabetes."
By improving the survival and integration of transplanted islets, the patented technology has the potential to increase the efficiency of donor tissue utilization. If fewer islets are required to achieve therapeutic benefit, more patients could potentially be treated using the same limited donor supply. The patent supports the potential for fibroblasts to play essential roles in tissue regeneration beyond their traditional structural functions.
