Study Shows Porcine Cells Can Help Wound Healing

An acellular cholecyst extracellular matrix (p-CEM) of porcine origin was prepared using iStock_000002065074_Smallanionic 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.

This research is just the latest study using porcine materials to advance medical treatment. Past studies have used pig models to look at repair to damaged hearts and genome reprogramming.

What Porcine Tissue Tells Us About Heart Disease

post mortem porcine tissueHeart disease is a leading cause of death in the US today and patients that survive a myocardial infarction have a low five year survival rate. Therefore there is a great need for regenerative approaches for stimulating repair.

Gene electro transfer (GET) to the left ventricular myocardium is a promising technique for delivery of therapeutic genes for the treatment of ischemia, myocardial infarction and heart failure directly to the effected myocardium. In this study a small animal model (rat) and a large animal model (porcine) were used for gene delivery to non-ischemic and ischemic left ventricular myocardium.

Gene expression was evaluated histologically for location of expression within the myocardium as well as quantitatively via ELISA.  These animal models allow for the evaluation of therapeutic potential of particular gene delivery as well as translation to clinical settings.

Past studies have shown post mortem porcine tissue effective in studying bone regeneration and other human health issues.
