Our expert team provides customized model selection, study design, and full-service execution to accelerate your oncology research.

Bladder cancer remains a significant global health challenge, with high rates of recurrence and progression. Robust animal models are critical for understanding disease mechanisms, identifying therapeutic targets, and evaluating candidate treatments before clinical translation. Alfa Cytology utilizes a diverse range of species, including Mus musculus (mouse), Rattus norvegicus (rat), and Gallus gallus (chicken), encompassing immunocompetent, immunodeficient, and transgenic strains such as Balb/c, C57BL/6, NSG, NOD, CB17, C3H/He, and others. These models recapitulate essential features of human bladder cancer, including tumor heterogeneity, metastatic potential, resistance phenotypes, and immune interactions, thereby providing scientifically valid platforms for both mechanistic and therapeutic studies.

Chemically-Induced Models

Chemically-induced bladder cancer models involve the administration of carcinogens such as N-butyl-N-(4-hydroxybutyl) nitrosamine (BBN) or hydroxybutylbutyl nitrosamine to rodents, typically via drinking water or intravesical instillation. This methodology mimics the stepwise development of bladder tumors from normal urothelium through dysplasia to carcinoma, closely resembling the pathogenesis observed in human disease. Key advantages include the induction of multifocal, heterogeneous tumors within an intact immune system, allowing for the study of tumor initiation, progression, and immune response. These models are ideal for evaluating chemopreventive agents, immunotherapies, and the influence of genetic or environmental modifiers on tumorigenesis.

Xenograft and Patient-Derived Xenograft (PDX) Models

Xenograft models are established by implanting human bladder cancer cell lines or tumor fragments into immunodeficient mice or rats (e.g., Balb/c nude, NSG, NOD, CB17, Rowett). PDX models utilize direct transplantation of patient tumor tissue, preserving the genetic, histologic, and molecular heterogeneity of the original cancer. Orthotopic, subcutaneous, and metastatic models are available, including luciferase- or GFP-labeled lines for non-invasive imaging. These models offer high translational relevance, enabling the assessment of drug efficacy, resistance mechanisms, and biomarker discovery in a clinically representative context. PDX models are especially valuable for personalized medicine approaches and for evaluating therapies against specific genetic backgrounds or resistance phenotypes.

Syngeneic and Allograft Models

Syngeneic models are created by implanting murine bladder cancer cell lines (such as MB49 or MBT2) into immunocompetent mice of the same genetic background (e.g., C57BL/6, C3H/He). Allograft models use genetically matched or closely related strains for tumor implantation. These models preserve the host immune system, enabling the study of tumor-immune interactions, immunotherapy efficacy, and tumor microenvironment dynamics. They are particularly suited for evaluating immune checkpoint inhibitors, cytokine therapies, and combination regimens targeting both tumor and immune compartments.

Genetic and Transgenic Models

Genetic models include knockout (e.g., Trp53, Rgs6, ARID1A, MTAP) or transgenic mice expressing oncogenic drivers (e.g., FGFR3, Stat3). These models spontaneously develop bladder tumors or exhibit altered susceptibility to carcinogens, allowing for the investigation of specific gene functions in bladder carcinogenesis and therapeutic response. Genetic models provide powerful tools for target validation, mechanistic studies, and the evaluation of gene-specific therapies such as RNAi or gene editing.

Organoid and Ex Vivo Models

Patient-derived bladder cancer organoids are three-dimensional cultures established from primary tumor tissue, including genetically modified (knockdown, knockout, overexpression) organoids. These ex vivo systems enable high-throughput drug screening, mechanistic studies, and validation of findings from in vivo models. Organoid models are instrumental in precision oncology, facilitating rapid assessment of therapeutic responses and resistance mechanisms.

Alfa Cytology delivers a complete solution for in vivo bladder cancer model development and testing. Our services include model selection and customization, cell line or tumor tissue preparation, animal surgery and tumor implantation (orthotopic, subcutaneous, intravenous, or intravesical), treatment administration, and comprehensive study management. Key efficacy endpoints include tumor growth inhibition (measured by caliper, bioluminescent/fluorescent imaging, or MRI/CT), survival analysis, metastasis assessment, histopathology, and molecular biomarker analysis (IHC, qPCR, NGS, flow cytometry). Our analytical capabilities extend to pharmacokinetics, pharmacodynamics, immune profiling, and resistance mechanism elucidation. Rigorous quality control measures are implemented at every step, including authentication of cell lines, genotyping, sterility checks, SOP-driven procedures, and ethical compliance to ensure reproducibility and scientific integrity.
