Modulation of Oxidative Status by Normoxia and Hypoxia on Cultures of Human Dermal Fibroblasts: How Does It Affect Cell Aging?

Figure 5

Levels of coenzyme Q10 in HDF analyzed by HPLC. HDF were serially passaged under the two oxygen tensions (21% and 5%), and at matched cell passage, intracellular CoQ10 was analyzed at various stages of cellular aging—young (Y) and old (O) HDF. Total CoQ10 levels (a) and % of oxidized CoQ10 (b) in HDF. Error bars represent ± SD. ; .
