Additional file 1: of Tenascin-C expression contributes to pediatric brainstem glioma tumor phenotype and represents a novel biomarker of disease

Figure S1. TNC expression in pediatric glioma cell lines modified via shRNA and cDNA transfection in vitro. Pediatric supratentorial high-grade glioma (HGG n = 1) and brainstem glioma (DIPG n = 3) cell lines were modified via lentiviral transfection of TNC cDNA and shRNA constructs. Two distinct shRNA constructs, 232 and 234, were generated. a) TNC transcript level after transfection, measured via qPCR, demonstrating TNC shRNA knockdown (left) and cDNA amplification (right), relative to empty vector controls (**p = 0.005, ***p 95% in both cDNA and shRNA. Scale bar = 200 μm. (TIF 138230 kb)
