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. 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. 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 towards more humane and representative scientific investigations.

"Similar papers" are the closest papers from that journal in the model's embedding space. They show what the match is built on, but the ranking comes mostly from a classifier over the whole training set, not from these examples alone.
