Figure 1From: Differential cell reaction upon Toll-like receptor 4 and 9 activation in human alveolar and lung interstitial macrophages Morphology and CD90 staining. MΦ visualization by Pappenheim staining (A) and electron microscopy (B). Images are representative for cell preparations from at least two different donors. C: Comparison of MΦ sizes by forward scatter as measured by flow cytometry. Light grey line: IM; filled/dark grey: AM. D: CD90 staining of AM and IM. Filled/dark grey: isotype control; light grey line: antibody staining. MFI values are given within graphs. Data show one representative out of three independent experiments with cells obtained from different donors.Back to article page
