OBJECTIVE The purposes of this study were to establish intracervical tumors of the nude rat as an orthotopic experimental model for human cervical cancer and to preliminary evaluate the effects of the adenoviral vector, Ad5CMV-p53, on orthotopic cervical tumor size. METHODS Human cervical cancer SiHa and ME-180 cells were injected into the cervix of the nude rat. Four days later, 1 x 10(9) pl...

Murine cytomegalovirus replicated in reproductive tissue of male mice infected with the virus. We examined three strains of mice latently infected by injection at birth with 100 plaque-forming units of the virus. As adults, these mice contained within their testes 4--6 viral genomic equivalents per 100 cells, as tested by hybridization between mouse DNA and cytomegalovirus DNA. Acutely infected...

Rab25 is a newly discovered member of the Rab11 subfamily of the Rab protein family. The purpose of this study was to investigate the proliferation of derivatives of the human breast cancer cell line MCF-7 with different levels of expression of the Rab25 gene and their tumorigenicity in nude mice. The effect of different expression levels of the Rab25 gene on various biological activities of th...

In the preliminary study, we have found an excellent osteogenic property of nanohydroxyapatite/chitosan/poly(lactide-co-glycolide) (nHA/CS/PLGA) scaffolds seeded with human umbilical cord mesenchymal stem cells (hUCMSCs) in vitro and subcutaneously in the nude mice. The aim of this study was to further evaluate the osteogenic capacity of nHA/CS/PLGA scaffolds seeded with hUCMSCs in the calvaria...

Although normal mice eliminated the lumen-dwelling intestinal cestode Hymenolepis diminuta by day 21 post-cysticercoid inoculation, congenitally thymus-deficient (nude) mice maintained their work burdens. Nude mice grafted with thymus glands or injected with thymus cells eliminated their worms.

In 1960, Shepard10) reported a model of experimental leprosy of mouse by means of footpad inoculation technic. This experimental leprosy has been widely utilized in the field of leprosy research, but grwoth of Mycobacterium leprae in normal mouse foot-pad is limited and maximum harvest of M. leprae from infected normal mouse foot-pad is about 106. Several studies were reported concerning immuno...

Nude mice of NIH/Swiss background were utilized for the heterotransplantation of a tissue culture cell line derived from a human prostate adenocarcinoma metastatic to the brain. These cells, which had been grown in vitro for 13 passages, formed solid tumors when injected s.c. into nude mice. The cell line DU 145 has been passaged 60 times in vitro over a period of 18 months. Tumors removed from...

Mutation in the "nude" gene, i.e. the FoxN1 gene, induces a hairless phenotype and a rudimentary thymus gland in mice (nude mouse) and humans (T-cell related primary immunodeficiency). Conventional FoxN1 gene knockout and transgenic mouse models have been generated for studies of FoxN1 gene function related to skin and immune diseases, and for cancer models. It appeared that FoxN1's role was fu...
