Porcine tissues (including porcine heart valves, skin, pericardial tissue, organs, and more) have contributed to significant medical advancements in cardiology and wound care. Porcine heart valves have been commercially available since the 1970s, with hundreds, if not thousands, of patients receiving life-saving care due to this medical treatment option. Similarly, porcine tissue has also contributed to effective wound care for many patients, accelerating healing, reducing pain, and protecting wounds from bacterial and physical trauma. Medical professionals source porcine tissue from trusted porcine tissue suppliers to provide hope and healing for the patients in their care.
History of Porcine Tissue in Wound Care
One real-world application for porcine tissue use is wound care. Xenografts (tissue grafts from donors of a different species than the recipient) can act as a protective barrier during wound healing. This medical concept has been practiced since the 1500s, with xenograft tissue taken from dogs, cats, rats, chickens, cows, pigs, and more. Currently, porcine tissue is one of the most common materials for xenografts, due to the fact that it is cost-effective, readily available from high-quality porcine tissue suppliers, and similar enough to human cell structure that it proves effective in wound care.
Xenografts are not the only use of porcine tissue in wound care. Some medical professionals use porcine gelatin sponges for wound care, treating wounds with a sterile and absorbent material to stop bleeding. The material is absorbed by the body in less than two months and can be cut to fit the wound. Porcine small intestine tissue, porcine placenta, porcine hide, porcine-derived collagen, and other porcine tissues and organs are also utilized in wound care medical treatments.
Porcine tissue use in wound care is still being researched, and advancements are still being made. In the last decade, a new porcine skin-derived collagen matrix was developed to accelerate wound healing. The chemical content was similar to that of humans and was found to be nontoxic. This could provide another use for porcine tissue in wound care – in addition to the many uses already in practice today.
It is important to note that porcine tissue for use in wound care must be sourced from high-quality porcine tissue suppliers. When pigs are not raised in a clean environment, patients are more likely to encounter infection and other diseases, such as influenza. When exploring this possibility for a patient’s medical treatment, choose a supplier that meets industry benchmarks, holds appropriate certifications, employs meticulous processing, provides robust documentation, and engages in conversations to assure you of quality products.
Benefits of Porcine Tissue Xenografts
One common use of porcine tissue in wound care is porcine tissue xenografts, which provide many benefits. When applying a porcine tissue xenograft, the wound is first cleaned and treated with antibiotics (if needed). Once the wound is clean, the porcine skin is more likely to adhere and provide intended benefits. The patient generally must still be seen by a medical professional weekly, at a minimum, but is on the path to faster and greater healing.
Porcine tissue xenografts protect wounds from bacteria, contaminants, and the possibility of reopening or reinjury. Additionally, porcine tissue increases moisture and heat retention, contributes to faster healing, and reduces scarring. Possibly most importantly to the patients themselves, porcine xenografts also reduce a patient’s pain level. Xenografts for wound care can be done with tissue from various animals, but since the 1960s, porcine tissue has become the most common choice. In addition to its low cost and high availability, porcine tissue is also favored because it doesn’t incorporate into the wound bed, allowing it to be used as a temporary dressing without becoming vascularized.
Porcine Tissue Application in Cardiovascular Treatment
Porcine tissue has many medical applications outside of wound care, including playing a role in cardiovascular treatment. Doctors often choose to work with porcine tissue valves and other porcine tissues due to their similarity to human hearts in size, weight, and structure. Because of this ideal compatibility, porcine valves have now been transplanted into human patients for over fifty years. Porcine valve transplants last an average of ten years, with some lasting even longer (some are recorded to have lasted up to seventeen years). Valves will ultimately fail due to degeneration, but medical professionals have found ways to combat this downfall, including methods such as fixation and anti-calcification.
Although some patients choose non-biological transplant options, such as mechanical heart valves made of carbon, many choose biological valves made from materials such as porcine tissue to lessen the need for blood thinners and other long-term medication use. Porcine tissue is effective in heart transplant work for many reasons, including the fact that a pig’s heart and other organs are similar in size and structure to human organs.
Porcine valve replacement is not the only application for porcine tissue in cardiovascular settings. Porcine pericardial tissues have been used in cardiothoracic and vascular surgery, and surgeons are still attempting to xenotransplant genetically modified porcine hearts into human patients. This isn’t fully approved yet by the FDA, but research and medical advancements are headed in this direction – built on a foundation of hundreds of years of xenotransplantation research.
Why Porcine Tissue is an Ideal Choice for Heart and Wound Care
Porcine tissue is an ideal choice for cardiovascular and wound care for many reasons. First, the structure and function of porcine skin, organs, and other tissues are similar to humans, making it easier to study, use, and apply to human patients’ needs. Additionally, porcine tissue is more readily available than other options and often more cost-effective. There are many high-quality porcine tissue suppliers, including Tissue Source, that work with medical professionals.
In addition to heart and wound care, porcine tissue is now being used in chest wall reconstruction, cornea implants for vision restoration, breast reconstruction, rotator cuff tear treatment, wound healing products, surgical mesh, dental and orthopedic applications, and more. Developments in this field are being made regularly, such as the world’s first successful transplant of a genetically engineered porcine kidney into a living patient announced in 2024. Porcine tissue is proving more and more useful in medical applications, not just in research settings. Hundreds of thousands of patients will benefit from life-saving or life-enhancing treatment because of porcine tissue in the near future.
