Phenotypic analysis of freshly isolated CD14⁺ CD48⁺ decidual cells. (A) Surface expression of CD48 by CD14⁺ decidual cells. The percentages of positive cells are indicated in the upper quadrants. (B) Three-color immunofluorescence analysis was performed by staining double-positive cells (ie, coexpressing CD14 and CD48) with mAbs specific for one or another indicated surface markers. Gray profiles represent negative controls.
