ROS content in HUVECs, cardiac fibroblasts, and cardiomyocytes seeded in collagen gels. The Gel and Gel/O2 groups were injected into the collagen gels respectively and cultured under normal condition or hypoxia. ROS content was measured 2 days after injection. (A) HUVECs; (B) Cardiac fibroblasts; and (C) cardiomyocytes. *p < 0.05.
