Figure 2: Patterns of gene expression in hypoxia and atmospheric-exposed co-cultures differed during the culture period (A) NuFF/MDA231 co-cultures were assessed for changes in the expression patterns of genes important for ECM assembly, stability and angiogenesis along the culture period. Differences were observed between time points for each gene tested. *p≤0.05, **p≤0.01, ***p≤0.001.
