a Rad, b Rem1, c TNF-α, and d PDGF expression in standard healing fractures (black bars) and nonunions (gray bars) at post-fracture days 7, 14, 21, and 28, as analyzed by real-time PCR. All graphs show the fold change and range for each experimental group, normalized to the gene expression levels observed in standard healing fractures at post-fracture day 7. *p < 0.05 and **p < 0.01 indicate statistically significant difference between standard healing fractures and nonunions at the indicated time points
