Figure Lengend Snippet: Indirect effect of dextrose exposure on the metabolic activity of nascent fibroblasts 48 hours after treatment. After fibroblasts were treated with 5%, 10%, 15%, 20%, and 25% dextrose compared to media control for 15, 30, 60, and 120 minutes of exposure, the supernatant fluid was replaced with fresh media and the cells were maintained at 37°C, 5% CO 2 for 8 hours prior to collecting the supernatant fluid. Nascent fibroblasts (not exposed to dextrose) were then incubated with this supernatant fluid from dextrose-treated cells for 48 hours. XTT assay, displaying optical density (OD) readings of nascent fibroblasts 48 hours after being exposed to supernatant fluid taken from fibroblasts directly treated with dextrose, run in triplicate, n = 5, error bars represent SEM. * P < 0.05.
Article Snippet: The MRC-5 cells, a human lung fibroblast cell line (ATCC; cat# CCL-171), were cultured in complete medium made from Eagle’s Minimum Essential Medium (ATCC; cat# 3002003) supplemented with 10% fetal bovine serum (Atlanta Biologicals; cat# S11150 ), 1% penicillin/streptomycin (ATCC; cat# 30-2300), and 2 mM L-glutamine (ATCC; cat# 30-2214) according to the protocol for subculture recommended by ATCC.
