Morphology, homogeneity and functionality of XXXX monocytes-derived macrophages.

@entity1 @entity5750 @entity17614 @entity469 @entity1495
Primary cultures of @entity1 monocyte-derived macrophages (n = 50) were characterized in order to use this cellular model to establish a proteomic map of macrophages. Peripheral blood mononuclear cells were isolated from healthy donors' blood using density gradient centrifugation. The cell culture quality was checked in respect of several morphological and molecular aspects. The homogeneity and purity of cells was assessed after 12 days' primary culture with phase microscopy, immunocytochemistry and flow cytometry. Monocytes were completely differentiated into macrophages within 12 days as shown by phase microscopy. On day 12, all cells expressed @entity469 antigen and were negative for CD3. Flow cytometry experiments showed a purity of the primary culture on day 12, in a range between 76% and 98% of @entity5750 + cells. The functionality of cells was characterized for the presence of @entity17614 as an intracellular marker and for the presence of @entity1495 as a marker secreted into the culture medium. This study allowed to determine criteria of quality and functionality for the primary culture of monocyte-derived macrophages. Cultures meeting these criteria will be used for the proteomic analysis and the establishment of the reference map.
