(a) and (b) Cell morphology of mouse macrophages in the presence of LPS Cells images were taken by phase contrast microscope (original magnification, ×10). mMO (RAW 264.7) were cultured for 7days in the absence of LPS (a) and in the presence of 1 μg/mL LPS (b). (c) to (g) Osteoclast-like cells in RAW264.7 cultures induced by LPS and RANKL mMO (RAW 264.7) were incubated with 1 μg/mL of LPS or 200 ng/mL of RANKL for 7 days. TRAP staining images were taken by phase contrast microscope (c, e and h). Pit formation activity of osteoclasts was observed by SEM (d, f and g). (c and d) mMO seeded on CaP substrate (control), (e and f) treated with LPS and (h and g) treated with RANKL.
