Fig. 7From: Protective role of all-trans retinoic acid (ATRA) against hypoxia-induced malignant potential of non-invasive breast tumor derived cellsEffects of ATRA on CD133 expression in MCF10DCIS cells. Cytofluorimetrical analysis of CD133 expression in MCF10DCIS cells cultured for 96 h under normoxic and hypoxic conditions in the presence or absence of 1 μM ATRA. A phycoerythrin (PE)-conjugated anti-CD133 antibody was used and surface antigen expression is reported as percentage of positive cells. The data are the mean of three separate experiments performed in triplicate ±SD. *P < 0.05Back to article page
