RT-PCR screening of Cell Surface Biomarkers. Screening of mRNA isolated from the SCC cell lines and corresponding AiTS isolates revealed higher CD44 (cancer biomarker) mRNA expression among the SCC cell lines than the AiTS isolates. Conversely, CD133 mRNA (cancer stem cell) expression was highest among the AiTS isolates and much lower among the SCC cell lines
