Figure 1From: Comparison of angiogenesis-related factor expression in primary tumor cultures under normal and hypoxic growth conditionsCulture growth is comparable under normoxic and hypoxic conditions. A linear regression of the normoxic versus hypoxic percent confluency of each of the 50 samples in the study shows the confluencies to be similar within a given sample. Many samples reached 100% confluency in both conditions, so less than 50 points appear on the graph.Back to article page
