Figure 2From: Hypoxic conditions increase hypoxia-inducible transcription factor 2α and enhance chondrogenesis in stem cells from the infrapatellar fat pad of osteoarthritis patientsChondrogenic cultures of infrapatellar fat pad cells and the effects of hypoxia. Wet weight (a), glycosoaminoglycan (GAG) analysis (b) and GAG per DNA measurement (c) of cell aggregates after chondrogenic differentiation for 14 days under normoxic and hypoxic conditions. Results are means ± SEM (n = 3). **p < 0.001; *p < 0.05 (Student's paired t-test).Back to article page
