Porcine Tissue Used for Vitreous Cryopreservation Research

PigletVitreous cryopreservation is a practice that allows for the preservation of biomaterials without the risk of excess ice accumulation.

Porcine tissues are an excellent model for this sort of research. There are many stresses – internal, thermal, residual – induced by the rapid cooling process of vitreous cryopreservation.

By using porcine tissues, researchers can fine-tune the methods used in cryopreservation and improve the process, which in turn will allow for effective preservation of larger materials.

Since porcine hepatic tissue is so similar to the liver tissue found in humans, it is an excellent tissue model for vitreous cryopreservation research. A recent study in China – published in the March 2017 edition of the International Journal of Heat and Mass Transfer — used porcine hepatic tissue to look at vitreous cryopreservation.

Why Porcine Tissues Are Key For Researchers

porcine tissues used for researchPigs are increasingly being used as an alternative to animals like dogs and monkeys when it comes to surgical procedures and preclinical toxicology testing of pharmaceuticals.

That’s according to research published in the journal Veterinary Pathology.

“There are unique advantages to the use of swine in this setting given that they share with humans similar anatomic and physiologic characteristics involving the cardiovascular, urinary, integumentary, and digestive systems,” the authors write in the article “Swine as Models in Biomedical Research and Toxicology Testing.”

They continue:

“Ethical considerations, as well as the existence of significant amounts of background data, from a regulatory perspective, provide further support for the use of this species in experimental or pharmaceutical research studies. It is likely that pigs and minipigs will become an increasingly important animal model for research and pharmaceutical development applications.”
