Highly Mimetic Ex Vivo Lung-Cancer Spheroid-Based Physiological Model for Clinical Precision Therapeutics.

Abstract in brief

• The text discusses a new ex vivo lung cancer spheroid model that combines patient-derived tumor cells, endothelial cells, and decellularized lung matrix to closely mimic the behavior of native tumors, including oxygen gradients and biophysical properties.
• This model has been shown to accurately predict patient responses to chemotherapy and targeted treatments with 85% accuracy, 86.7% sensitivity, and 80% specificity, making it valuable for personalized medicine.
• RNA sequencing confirms that gene expression profiles of the spheroids closely match those of the original patient tumors, supporting its use in guiding clinical decisions and improving lung cancer treatment outcomes.
