Type of Cell Model | Advantages | Limitations | Additional Insights | References |
---|---|---|---|---|
iPSCs | Personalized Disease Modeling: Can be generated from patient samples, allowing personalized disease modeling | Complex Differentiation: Generating specific cell types from iPSCs can be challenging and time-consuming | iPSCs offer a unique opportunity for patient-specific research, but their complex differentiation can be a practical hurdle | [543] |
Disease Modeling: iPSCs can be differentiated into various cell types affected by cancer, providing a relevant model for studying disease mechanisms | Genetic Variability: iPSC lines may have genetic variations that can influence experimental outcomes | Researchers need to carefully account for genetic variability when working with iPSCs | [24] | |
Drug Screening: iPSCs can be used to test the efficacy and toxicity of potential cancer therapeutics before clinical trials | Tumorigenic Potential: iPSCs can form tumors if not properly differentiated or controlled | Stringent differentiation protocols are crucial to avoid tumorigenicity in iPSC-based models | ||
Traditional Cancer Cell Models | Established Cell Lines: A wide range of well-characterized cancer cell lines are available, enabling standardized experiments and comparisons | Genetic Drift: Cancer cell lines may undergo genetic changes over time, deviating from the original tumor characteristics | Periodic authentication and monitoring are essential to maintain genetic stability in cell lines | [546] |
Simplified Models: Traditional cancer cell lines can provide a simplified representation of specific cancer types, facilitating experimental manipulations and high-throughput screening | Lack of Tumor Microenvironment: These models often lack the complex interactions with stromal cells and immune components present in actual tumors | Traditional cell lines may not fully recapitulate the tumor microenvironment, limiting their translational relevance | [546] | |
Faster Experiments: Traditional cancer cell lines can proliferate rapidly, allowing for faster experimental results and drug screening | Limited Clinical Relevance: These models may not fully recapitulate the heterogeneity and complexity of tumors in patients | Rapid proliferation comes at the cost of potential oversimplification of cancer biology | [545] | |
Availability of Large-Scale Datasets: Many traditional cancer cell lines have extensive genomic and proteomic data available, aiding in data analysis and interpretation | Cross-Contamination: Cell lines can get contaminated or misidentified, leading to inaccurate or unreliable results | Data derived from cell lines should be interpreted with caution and validated using other models | [546] | |
Easy Manipulation: Traditional cancer cell lines can be easily manipulated genetically, allowing for targeted gene knockouts or overexpression studies | Metabolic Changes: Cell lines may exhibit metabolic alterations compared to primary tumor cells, affecting drug response and metabolism studies | Genetic manipulation offers experimental flexibility, but metabolic differences should be considered when assessing drug responses | [545] |
