Aim:
Exploring alternatives to in vivo models, this study validates Precision Cut Lung Slices (PCLS) as a viable ex vivo platform for lung cancer research. We established the prolonged viability and structural preservation of PCLS, essential for accurate drug response studies.
Material And Methods:
Using Paclitaxel as a benchmark drug and a therapeutically promising silver nanoparticles in combination with immunotherapy, we conducted a pioneering comparative analysis of its therapeutic effects on PCLS against traditional in vivo models.
Results:
Revealed that PCLS closely mimics in vivo responses, demonstrating comparable drug efficacy in tumor growth inhibition.
Conclusion:
This direct comparison not only confirms the utility of PCLS in simulating real-world outcomes but also emphasizes its potential in reducing animal testing. By providing a reliable, ethical, and efficient alternative for lung cancer studies, PCLS could significantly enhance preclinical research and drug development, marking a critical step toward more humane and representative scientific investigations.
