Xenotransplantation using pigs as donors offers the possibility of eliminating the chronic shortage of donor kidneys, but there are several obstacles to be overcome before this goal can be achieved. Preclinical studies have shown that, while porcine renal xenografts are broadly compatible physiologically, they provoke a complex rejection process involving preformed and elicited antibodies, heig...

BACKGROUND Keratinocyte growth factor (KGF)/KGF receptor (KGFR) signaling produces a rapid increase in the progression of breast cancer. Molecular modeling was used to create a group of KGFR-selective kinase inhibitors (TKI). Compound L-27 is a potent and selective KGFR TKI. The present study examined the oncolytic potential of L-27 using a breast cancer xenograft model. MATERIALS AND METHODS...

BACKGROUND The objective of the present study was to evaluate the efficacy of a simple, versatile and cost-effective immunosuppression protocol, using cyclosporine, ketoconazole and cyclophosphamide drug regimen to develop human tumor xenograft in mice. MATERIALS AND METHODS Cyclosporine, ketoconazole and cyclophosphamide drug regimen was administered to C57BL/6 mice to induce immunosuppressi...

We recently reported several driver genes of biliary tract carcinoma (BTC) that are known to play important roles in oncogenesis and disease progression. Although the need for developing novel therapeutic strategies is increasing, there are very few BTC cell lines and xenograft models currently available for conducting preclinical studies. Using a total of 88 surgical BTC specimens and 536 immu...

The histopathology of cardiac xenograft rejection has evolved over the last 20 yr with the development of new modalities for limiting antibody-mediated injury, advancing regimens for immune suppression, and an ever-widening variety of new donor genetics. These new technologies have helped us progress from what was once an overwhelming anti-Gal-mediated hyperacute rejection to a more protracted ...

A comparative study on tumorigenicity was carried out in which two Epstein-Barr virus (EBV) genome-positive epithelial cell lines (A2L/AH and NPC-KT) were tested in nude mice xenograft system and chick embryo system. When two cell lines were inoculated subcutaneously in nude mice and on chorioallantonic membrane of the chick embryo, respectively, tumors developed in both systems. Histologically...
