At Sustainable Swine Resources (SSR), we understand that some of the most valuable porcine materials are not always the most familiar. One example is porcine small intestine submucosa, often referred to as SIS. This material has become an important part of regenerative medicine because of its role as an extracellular matrix, or ECM, scaffold. In simple terms, SIS can help provide a structure that supports the body’s natural tissue repair process.
For life science companies, medical device developers, and researchers, porcine SIS offers a biologically active material with broad potential across wound care, soft tissue repair, cardiovascular applications, and other areas of tissue regeneration.
What Is Porcine Small Intestine Submucosa?
Porcine small intestine submucosa is a thin layer of tissue taken from the small intestine of a pig. It is processed to remove cells while preserving the extracellular matrix, which is the natural structural framework found in tissue. This framework contains components that help provide support for cell attachment, migration, and remodeling.
In regenerative medicine, SIS is valued because it can serve as a scaffold. Once prepared and applied in the right setting, it gives the body a structure to work with as new tissue forms. Research describes SIS-derived ECM as a biomaterial used in clinical applications for tissue repair, with interest across areas such as wound healing and cardiovascular repair.
Why SIS Matters in Regenerative Medicine
Regenerative medicine focuses on helping the body repair, replace, or restore damaged tissue. Instead of relying only on synthetic materials, many regenerative technologies use biologic scaffolds that interact with the body’s own healing processes.
Porcine SIS is important because it offers a natural tissue architecture that can support healing. Studies have described SIS as containing extracellular matrix components that support angiogenesis, cell migration, and cell proliferation, all of which are important parts of wound repair and tissue remodeling.
This makes SIS useful in applications where the goal is not simply to cover or reinforce tissue, but to help create an environment that encourages organized repair.
Common Uses for SIS-Based Materials
SIS-based materials have been explored and used in a range of clinical and product-development settings. Some of the most common areas include:
- Wound care: SIS can be used as a biologic scaffold to support healing in difficult wounds.
- Soft tissue reinforcement: SIS-based materials may be used to support repair where tissue has been weakened or damaged.
- Cardiovascular repair: Porcine SIS extracellular matrix has been studied as a scaffold for cardiovascular tissue repair and remodeling.
- Hernia and abdominal wall repair: SIS has been studied as a biologic mesh or patch material in surgical repair applications.
- Research and product development: Because SIS is biologically derived and adaptable, researchers continue to explore new applications for tissue repair and regeneration.
The value of SIS comes from its combination of structure, bioactivity, and versatility. Depending on the intended use, it can be prepared in different formats and processed to meet specific product requirements.
How SIS Compares to Synthetic Materials
Synthetic materials can provide strength, shape, and durability, but they do not always interact with the body in the same way biologic materials do. SIS-based materials offer a different approach. They are derived from natural tissue and designed to support tissue integration and remodeling.
For many medical device developers, this makes SIS an important option when building products that need to work with the body’s natural healing process. While every application has its own requirements, porcine-derived ECM materials can provide a biologically active alternative for teams developing next-generation solutions in wound care, soft tissue repair, and regenerative medicine.
Why Quality and Processing Matter
The performance of SIS-based materials depends heavily on how the tissue is sourced, prepared, and handled. Developers need materials that meet defined specifications, align with their processing requirements, and support reliable downstream performance.
At SSR, we work closely with partners to understand their application, specifications, and standard operating procedures. Our team can help develop customized protocols for harvesting, processing, preservation, and shipping. When projects require highly specific preparation, we can utilize designated medical-material rooms at our abattoirs, staffed by Good Manufacturing Practice-trained personnel.
SSR is ISO 22442-2 compliant and sources porcine tissues from two SQF-certified Johnsonville facilities located in Wisconsin and Kansas. Our facilities are USDA-inspected and regulated, with Quality Management Systems, SQF certification, and robust HACCP plans in place.
Supporting the Future of Regenerative Medicine
Porcine SIS continues to play an important role in regenerative medicine because it offers what many advanced therapies need: a natural scaffold, biologic compatibility, and flexibility across applications. From wound care to soft tissue repair, SIS-based materials help product developers create technologies that support healing in more sophisticated ways.
At SSR, we are proud to supply high-quality porcine materials that help researchers and manufacturers explore what is possible with SIS and other porcine-derived tissues. Whether your team is developing a medical device, refining an ECM-based product, or exploring a new regenerative application, we can help source and prepare materials to your exact needs.
