Cancer stem cells (CSCs) are known contributors to this cisplatin chemoresistance in HNSCC. The mechanistic target of rapamycin (mTOR) pathway, which is frequently dysregulated in HNSCC, plays a crucial role via the PI3K\/AKT\/mTOR axis in maintaining CSC populations and promoting cancer proliferation. However, the specific effects of combining rapamycin, an mTOR pathway inhibitor, with chemotherapeutic agents on CSC maintenance and overall tumorigenicity remain unclear.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>We examined CSC gene expression in HNSCC cell lines (HSC4, SCC25, OT\u20101109) and evaluated the therapeutic potential of combining rapamycin, an mTOR pathway inhibitor, with cisplatin on CSC using a cell viability assay. The combination was further evaluated in an HSC4 mouse xenograft model. Tumor volume and animal weight were monitored throughout treatment. Xenograft tissue analysis via immunohistochemistry assessed stem cell markers (CD133 and ALDH1A1), proliferation markers (Ki\u201067), and mTOR pathway inhibition (pS6).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Administration of low\u2010dose cisplatin enriched the CD133\n                      <jats:sup>+<\/jats:sup>\n                      cell population but failed to decrease the tumor mass in HNSCC xenografts.
