Phase contrast microscopy of living bone marrow derived macrophages. These cells are highly motile and the snapshot catches lamella and ruffles where the cells are protruding and phase dense organelles inside the volumes of the cells.
Cells were extracted from a mouse femur and plated in a coverslip bottom well (MatTek) in standard culture media. The Olympus IX 71 microscope had a simple heated stage. Cells were imaged with a 60X N.A. 1.4 phase 3 planapo objective with a Cooke Sensicam QE operated by IP Lab software running on a Dell Windows XP computer. This picture is one of a series that may be composed into a montage to see a large field of cells interacting while preserving the high magnification. Some of the pixels in this and the neighboring images are saturated.
