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.

Cryogels for Wound Care Applications in Porcine Models

Pigs.As we’ve pointed out in previous blog posts, porcine models are helpful in the study of human wound healing, because pigs and humans have very similar skin.

Porcine models played a role in a recent study at the University of Reading in Great Britain that looked at the use of cryogels and hydrogels in wound care applications.

Hydrogels are well known for their ability to aid in wound healing by accelerating the healing process such as reducing the amount of dehydration in the wound bed and absorbing exudate.
