Brief Definitive Report CULTURE OF MONONUCLEAR PHAGOCYTES ON A TEFLON SURFACE TO PREVENT ADHERENCE*

Culture of mononuclear phagocytes on a teflon surface to prevent adherence

A method is described for the culture of mononuclear phagocytes in suspension by incubation on a Teflon film to which the cells do not adhere. The characteristics of peritoneal macrophages, bone marrow mononuclear phagocytes, macrophage cell lines, and fibroblasts cultured in this way are similar to those observed after culture on glass or plastic surfaces. Culture of mononuclear phagocytes in ...

Culture of Mononuclear Phagocytes on a Teflon Surface to Prevent Adherence*

Characteristics of long-term cultures of proliferating, mononuclear phagocytes from bone marrow.

The characteristics of murine bone marrow mononuclear phagocytes in long-term cultures with embryonic fibroblast-conditioned medium were studied to determine the stage of development and state of activation of these cells. Two liquid culture systems were used: for studies on the morphology, cytochemistry, and functional characteristics at the cellular level, the cells were cultured adherent to ...

Paradoxical priming effects of IL-10 on cytokine production.

IL-10 is a well-known immunosuppressive and/or anti-inflammatory cytokine. However, we report in vitro experimental studies in which IL-10 primed leukocytes and led to an enhanced production of tumor necrosis factor (TNF) upon further stimulation by lipopolysaccharide (LPS). Monocytes and peripheral blood mononuclear cells (PBMC) prepared from whole blood maintained for 20 h at 37 degrees C in ...

The influence of culture conditions and serum lipids on interleukin-1 production by human monocytes.

Reliable assessment of IL-1 production by human monocytes is critically dependent on the methods for isolation and culture of these cells. In the present study, the quality of pipettes and the preparation of Ficoll-Isopaque appear to be crucial for IL-1 production from both LPS-stimulated and unstimulated monocytes. Different brands and lots of polystyrene culture wells give rise to great varia...
