Stents have long been a part of the lives of people. It is critical to keep clots and emboli in check to maintain the vascular health of people. Stent retriever mechanical thrombectomy is used standardly in treatment of strokes. The research done in this article on thrombectomy in acute stroke treatment is groundbreaking. The NeVa thrombectomy device is showing that it is able to collect and therefore remove large clot occlusions from the vascular system and achieve near-full to full reperfusion. The design of the device lends itself very well to capturing these clots. Swine are the model of choice for this study because their vascular system so closely matches the human vascular system.
We’re proud of the work our animals help researchers accomplish and look forward to contributing research swine to help in similar breakthroughs in the future.
In addition to offering live porcine models and porcine tissue, we’re also happy to offer clients our expertise in selecting the right animal model and/or animal tissue to utilize in their research.

Orthopedic surgeons are finding a rapid repair for rotator cuff tendon injuries where there was not a reliable method in the past. Porcine intestinal tissue has been determined to make a viable patch which allows the surgeons to have tissue to suture the tear together and aids in stimulating the body to grow new tendon tissue. The pig tissue, which is mostly collagen, then is absorbed by the body. This finding was reported by ABC News’ Denise Dador and ABC News.com’s Robin Eisner.

Pigs are a natural source for xenotransplantation due to the fact that they are so anatomically similar to humans. The key is to genetically modify the animals by knocking out the genes that are responsible for initiating the human immune system.
Research studies that have been carried out over the last year at The National Heart, Lung and Blood Institute (NHLBI) have shown that genetically altered porcine hearts that are transplanted into baboon’s abdomens are withstanding rejection along with a little help from host targeted immunosuppression. It is the hope of the scientists that all major organs will be able to be xenotransplanted including insulin producing cells which would treat diabetic patients.
This procedure will hopefully mean fewer potentially toxic drugs for immunosuppression. This is critical research because it may solve the shortage of human donor organs. Please click the link for “Pig Heart Transplants For Humans Could Be On Their Way” by Janet Fang to read the article.
Pigs are a major contributor to the biomedical research world. A new method of using porcine bladder tissue to create human muscle repair using a stem cell technique is proof. The University of Pittsburgh School of Medicine and The McGowan Institute for Regenerative Health has been testing this procedure in clinical studies and found that it works. This technique actually causes functional skeletal muscle to be formed where only scar tissue would normally form and the new muscle fibers actually secure their own blood flow. This tissue was used in the past to repair hernias and ulcers on the skin.
