Orthotopic model of SHG-44 in the enhanced green fluorescent protein nude mouse.

Naturally fluorescent proteins have been widely used in biological research. In this study, we found that the simple and effective way to obtain enhanced green fluorescent protein (EGFP) nude mice is to cross transgenic EGFP C57BL/6J mice with nude (nu/nu) mice. EGFP expression is identified by tail genotyping.

Anti-human CD133 monoclonal antibody that could inhibit the proliferation of colorectal cancer cells.

CD133, a five-transmembrane molecule, has been found on many types of cancers and determined to be a cancer stem cell biomarker. In this study a functional anti-human CD133 MAb 6B6 was obtained, and the specificity of this MAb was verified by flow cytometry. This MAb effectively recognized the CD133 molecule expressed on a series of malignant cell lines.

[Transplantation of human glioma stem cells in nude mice with green fluorescent protein expression].

Objectives: To investigate the possibility of transplantation of human glioma stem cells (HGSCs) in nude mice stably expressing green fluorescent protein (GFP) so as to clearly identify the incubated HGSCs from the host tissues.

Methods: Transgenic C57BL/6J mice expressing GFP was crossed with nude mice of the line NC, then hairless male nude mice expressing GFP were crossed with hairy female pubescent mice to obtain nude mice with GFP expression the expression of GFP in the skin and organs of these nude mice were evaluated by naked eyes, and immunohistochemical and immunofluorescence assays. HGSCs were transplanted orthotopically into the caudate nuclei of nude mice expressing GFP.

[Immune response and immunopathology in inducible costimulatory molecule (ICOS) transgenic mice infected with Schistosoma japonicum].

Objective: To establish the ICOS transgenic mice schistosomiasis japonica model and to observe the immune response and immunopathology of the model.

Methods: The transgenic mice were infected with Schistosoma japonicum. Spleen cells and sera of mice were harvested at week 4, 6, and 8 after infection.

[The study of sperm cryopreservation in kunmin (KM) mouse].

Spermatozoa of 10, 15 and 20-wk-old KM mice were frozen and stored at--196 degrees C. After thawing, intact superovulation oocytes were inseminated in vitro with relative high motility frozen/thawed mouse spermatozoa. Some 2-cell embryos obtained by in vitro fertilization were transferred to pseudopregnant recipients and 47%-56% of them developed into live-born offspring.
