<p>This study introduces a novel computational model that integrates cancer stem cells (CSCs) and the plasminogen activation system, filling a crucial gap in cancer research. While theoretical models have separately explored CSCs and the plasminogen activation system, no prior computational framework has combined these elements. Our model focuses on the invasion dynamics of CSCs, emphasizing the critical interactions between urokinase plasminogen activator (uPA) and plasminogen activator inhibitor-1 (PAI-1). We employed reaction–diffusion equations and analyzed the determinant and eigenvalue spectra of the Jacobian matrix of the system to identify instability regions within tumors. The findings revealed that the production and binding of uPA and PAI-1 significantly enhance the invasiveness and motility of CSCs, resulting in more complex and aggressive tumor structures. Our study advances the theoretical understanding of cancer dynamics by integrating these two critical biological processes into a single computational framework. This work builds upon and extends previous models by offering a more comprehensive analysis of tumor growth, with significant implications for optimizing cancer treatment strategies. The insights of the model into the interplay between CSCs and the plasminogen activation system offer a valuable tool for both research and potential clinical applications, paving the way for more targeted and effective therapeutic approaches.</p>
