Altogen Labs Invivo Xenograft Services

Altogen Labs http://altogenlabs.com provides invivo xenograft services http://altogenlabs.com/pre-clinical-r.... Xenografting is the transplantation of tissue from one species into another. Typically, immunodeficient mice serve as hosts for a wide variety of human tumors, effectively serving as models for human subjects. Xenografting has been established as benchmark studies in pre-clinical cancer research. Xenografting a complete and accurate study of tumor growth and the activity of drug administration. -Advantages of Xenografting Develop new therapeutic agents quickly, efficiently and cost-effectively Evaluate the efficacy and toxicity of potential therapeutic agents Evaluate target compound activity using in vivo system (human cells) Predict cytotoxicity of cancer drugs -Xenograft Study Pipelines Pipeline Xenograft Assay I Our staff designs the study based on your project requirements and objectives. Leveraging years of knowledge and experience, Altogen Labs guarantees an optimized experimental approach with respect to mice selection, cell lines, inoculation, and dosage. Pipeline Xenograft Assay II Testing a Compound The client provides a compound and cell line to be researched. Our staff will establish a xenograft animal model and test compound activity and how it affects tumor growth. Pipeline Xenograft Assay III Testing a Cell Line The client provides a cell line, and our staff tests its ability to establish tumor growth in standard immunodeficient mice. -Compound Testing Objectives How does the test compound affect tumor growth? Does the test compound inhibit tumor invasion or metastasis? Localization of test compound in the tumor? Define drug characteristics: Bioavailability Toxicity Efficacy Potency Is the cell line tumorigenic? Changes in gene expression upon treatment or gene manipulation How does gene manipulation in a cell line tumor growth, invasiveness, and metastasis -Basic Xenograft Study Xenograft studies can be designed to: Identify lead compounds Optimize dose schedules Identify combination strategies -Xenograft Service Options Use in-house or customer-provided cell lines 150 in-house cell lines available Begin testing a compound immediately after injecting mice with tumor cells (unstaged) or once the tumors reach a certain size (staged) Assign mice to groups randomly or stratify them by body weight, tumor size, disease factors, or any combination of parameters Administer test compounds by any of the following methods: topically, IP, IV, SC, PO, high pressure tail vein, osmotic minipumps (SC or IP), SC drug pellets, or in the food or water Snap freeze harvested tumors or fix them for histology or other specialized assays Analyze blood chemistry at various times throughout the study -Growth Rates for Different Cell Lines -Sample Cell Lines Available -Drug Administration Variables Route of dose: Intratumoral Intramuscular Oral Intravenous Intratracheal Subcutaneous Intraperitoneal Frequency of dose Duration of dose -Data Endpoints Estimated tumor volume (L x W2 /2) Mean/median time to specified tumor volume Survival time to specified tumor volume Tumor doubling time Tumor growth inhibition (TGI) Tumor growth delay (TGD) Increased life span (ILS) Tumor cell kill rate -Expanded Xenograft Services Clinical observations daily Haematology analysis (blood cell count) Clinical chemistry profile (of urine and plasma) Assessment of metastasis Characterization of the tumor (necrosis, etc) Tumoral tissue will be banked and preserved for further analysis Cryo-preservation (for cell culture) Formalin-fixed tumors and tissues (for histopathological and immunostaining analysis) RNA later fixed tumors and tissues (for RNA isolation and gene expression analysis) -Altogen Labs’ team of scientists carries extensive experience in Xenograft model research Altogen Labs is compliant as a Good Laboratory Practices (GLP) environment, which is required by the FDA for pre-clinical research.
