Surface expression of the macrophage-associated differentiation Ags was assessed by direct immunofluorescence (thick lines). ZK1 cells were incubated with FITC-labeled anti-mouse F4/80 or FITC-labeled anti-mouse CD11b. Mouse IgG2a and IgG2b were used as isotype controls (light lines). Staining of cells with FITC-labeled anti-mouse Ig compared to unstained cells detects the of cells expressing su

C capacity functionally, but like primary AMs deficient in MARCO and SR-AI/II, ZK cells were significantly impaired in phagocytosis compared to the WT AMs due to deficiency in scavenger receptors.-Page 5 of(page number not for citation purposes)Particle and Fibre Toxicology 2008, 5:http://www.particleandfibretoxicology.com/content/5/1/A.

Cell lines from primary alveolar macrophages from MS-/- mice. Results: We used in vitro infection of the primary AMs with the J2 retrovirus carrying the v-raf and v-myc oncogenes. Following initial isolation in media supplemented with murine macrophage colony-stimulating factor (M-CSF), we subcloned three AM cell lines, designated ZK-1, ZK-2 and ZK-6. These cell lines grow well in RPMI-1640-10 FB

Line was purchased from ATCC, and cultured in Dulbecco's Modified Eagle's Medium (DMEM) supplemented with 10 fetal bovine serum (FBS) and gentamycin (50 g/ml). ZK cell lines in this study were cultured in RPMI 1640 complete medium, in which RPMI medium was supplemented with 10 FBS, L-glutamine (2 mM), penicillin (100 U/ml), streptomycin (100 g/ ml). Isolation of alveolar macrophages Alveolar mac

Night at 37 . Unopsonized (as negative control) or preopsonized SRBC were plated on monolayer of ZK1 cells at a ratio of 20:1 and incubated at 37 for 1 h. After removal of free SRBC by medium exchange and lysis by osmotic shock, the cells on the cover glass were fixed and stained with a modified Wright stain, subsequently examined by light microscopy. Panel A, ZK1 cells were unable to ingest unop
