The effect of hypoxia on in vitro clonogenicity in HMM cells. (a) Hypoxia enhanced the colony forming ability of HMM cells. Representative microscopic examinations are presented. P value was calculated by Student’s t-test. Hypoxia significantly upregulated the expression of Oct4 at transcriptional (b) and translational (c) levels in HMM cells. P value was calculated by one-way ANOVA with Bonferroni post-test. *P value < 0.05, **P value < 0.01. Abbreviations: N, normoxia; H, hypoxia
