Colony-forming cells (CFCs) assayed at 3% vs 21% O 2 . (A) Cloning efficiency (frequency of single satellite cells that generated a colony in a single well) under low (3%) oxygen and ambient (20%) oxygen. Blue bars represent mean and 95% confidence intervals. (B) Number of nuclei per colony for the low and ambient oxygen groups. Blue bars represent mean and 95% confidence intervals. (C) The coefficient of differentiation, Df, for the two experimental groups. Blue bars represent mean and 95% confidence intervals. (D) The fusion index, Ui, for the two experimental groups. Blue bars represent mean and 95% confidence interval. Blue bars represent mean and 95% confidence intervals.
