Research swine are playing an important role in the global fight against COVID-19, with live animal models helping to both create a vaccine and address the worldwide ventilator shortage.
Research swine are contributing to research studies that focus on restorative therapies to replace lost or diseased human tissues.
While the amount of suitable human cells for transplantation is lacking, porcine cells offer researchers a suitable, and much more available, alternative.
In 2014, researchers from the University of Pittsburgh found that cells derived from porcine organs – in this case, bladders – could work with human stem cells help build muscles in the legs of five men who had suffered severe injuries, including two soldiers injured by IEDs.
All five had suffered from nearly 60 percent to 90 percent of leg muscle loss, and had undergone surgery and physical therapy, with no success.
An acellular cholecyst extracellular matrix (p-CEM) of porcine origin was prepared using anionic biological detergent and the healing potential compared with commercially available collagen sheet (b-CS) and open wound (C) in full-thickness skin wounds in rats.
Healing was evaluated on the basis of wound contraction, gross, hematological, immunological and histopathological observations. It was found that p-CEM had healing potential and was shown to have a better healing response than commercially available collagen sheet to reconstruct full thickness skin wounds in rats.
This study illustrates the better healing qualities of porcine extracellular matrix when compared to commercially available collagen sheets and open wound in full-thickness skin wounds in rats.

Donor cell types with distinct potential competence may offer different epigenetic flexibility for subsequent genome reprogramming in SCNT.
To improve the efficiency of cloning, porcine mesenchymal stem cells (pMSCs) were isolated and well identified by 6-channel flow cytometry and differentiation assays and were used as donors in SCNT. The results suggest that the epigenetic status of donor cells has an improvement on genome reprogramming, and multipotent pMSCs favored subsequent embryonic development.
