Figure 4. Percentage of major steroids produced by AA cells with/ without ACTH treatment.
Primary human adrenal cells were isolated as described in Materials and Methods, and plated at a density of 300,000 cells/well in 24-well dishes. Cells were treated with/without ACTH (10nM) in 0.1% experimental medium for 48 h before harvest. The concentration of steroids in the medium was measured by LC-MS/MS and normalized to the amount of protein. Percentage of each steroid was calculated by dividing the amount of individual steroid with total steroid. A. Table summarizing the percentage of individual steroid compared to total steroid produced by AA cells. B. Pie chart summarizing the relative percentage of the major steroids produced in AA cells. Data represent results from three independent experiments and shown as means ± S.E.M; ND, not detectable.
