CD133 mRNA expression in primary (P) and recurrent (R) tumor tissue. Total RNA was extracted from both primary and recurrent tumor tissue derived from five patients. CD133 mRNA expression was measured by real-time qPCR. The relative CD133 mRNA level of recurrent tumor was presented as the fold increase compared to that of autologous primary tumor tissue (see Methods). Data are representative of two independent experiments.
