In this protocol, a method of murine islet isolation and transplantation into the inguinal subcutaneous white adipose tissue is described. Isolated syngeneic murine islets are transplanted into a murine recipient using a basement membrane hydrogel. The blood glucose level of the recipients is monitored, and histology analysis of the islet grafts is performed.

Quantification of Circulating Pig-Specific DNA in the Blood of a Xenotransplantation Model

Yangyang Deng^*1,2, Ming Zhou^*1,3, Ying Lu¹, Jiao Chen¹, Zuhui Pu⁴, Dongjing Yu^1,5, Yifan Dai⁶, Yongqiang Zhan⁷, Lisha Mou¹

In this protocol, porcine specific primers were designed, plasmids-containing porcine specific DNA fragments were constructed, and standard curves for quantitation were established. Using species-specific primers, cpsDNA was quantified by qPCR in pig-to-mouse cell transplantation models and pig-to-monkey artery patch transplantation models.
