Figure 6

CD14⁺/ColI⁺ cells are present in SSc-ILD lung tissue. Fixed, paraffin-embedded adult lung tissue sections from normal and SSc-ILD subjects were stained for CD14 and ColI. Nuclei were stained with DAPI (blue). Top: low-magnification images showing SSc-ILD adult lung tissue. Bottom: high-magnification images showing SSc-ILD adult lung tissue. The portion of the low-magnification image presented at high magnification is boxed. ColI, green; CD14, red. Note that CD14⁺/ColI⁺ cells are present in SSc-ILD lung tissue, but not in normal lung tissue. Bar = 10 μm.
