Overall, neutrophils were rarely observed and NSC were mainly epithelial cells or cellular debris, as demonstrated by MPO immunocytochemistry.
The matrix of the keratinous cyst contains mainly epithelial cells (keratinous cells) with different differentiation states [ 4].
These receptors, as TLRs, are expressed in cells continuously exposed to bacteria, mainly epithelial cells, macrophages, and dendritic cells [ 56, 57].
As shown in Fig 5, mainly epithelial cells were TUNEL-positive, although some cells beneath the bronchi, most likely inflammatory cells and mesenchymal cells, were also TUNEL-positive.
IL-22 is known to have a relationship with virus-infection reactions and whose receptor is confined to non-hematopoietic cells (mainly epithelial cells).
Mechanical dissociation of cells from selected regions of prostate specimens yielded mainly epithelial cells, as revealed by cytokeratin and PSA staining.
This might reflect the fact that CaExPA contains mainly epithelial cells and/or a different role for miR-21 in CaExPA.
Alternatively, these vesicles may fuse with other autophagic or heterophagic compartments containing bacteria., Furthermore, the presented data show that during M. marinum infection the larger bacteria-containing GFP-Lc3 vesicles occur more often in leukocytes than in other cell types (mainly epithelial cells in the tail fin).
This study also indicates that PCV1 and PCV2 have different cell tropism during foetal life, since PCV2 replicates mainly in the cardiomyocytes and macrophages of the heart tissue [ 26] and PCV1 targets mainly the epithelial cells of the lungs.
CF is caused by mutations in the CFTR gene, encoding an apical cell-surface chloride channel expressed mainly in epithelial cells.
