Figure 4From: Comparison of immature and mature bone marrow-derived dendritic cells by atomic force microscopy Quantitative analysis of the surface roughness and the height of immature and mature BMDCs. (A, B) AFM was exploited to show topographic images of the surface nanostructure of the immature BMDCs treated with 10.0 μg/L of GM-CSF plus 10.0 μg/L of IL-4 (A) as the control or the mature BMDCs stimulated with 1.0 mg/L of LPS (B) in the same scanning area of 5 × 5 μm; (C) The root-mean-square roughness (R rms or R q) and average roughness (R a) on the surface of the immature BMDCs (A) and the mature BMDCs (B) were quantitatively analyzed via the formulas as described in the section of "Materials and methods." (D) The average heights of immature and mature BMDCs were statistically quantified, respectively. n = 10; *P < 0.05, compared with the control.Back to article page
