Abstract:: In this descriptive flow cytometric study we analyzed the phenotype of human large granular lymphocytes from the decidua (DLGL) of first-trimester pregnancy. Expression of CD56 at high density on DLGL suggests a relationship to the small CD56bright+ subpopulation of peripheral blood natural killer (PBNK) cells. In comparison, these cell types differ in respect to the expression of a variety of adhesion molecules and receptors implicated in homing, migration and activation. In contrast to CD56bright+ PBNK cells, DLGL were still brighter for CD56 and show higher expression for CD29 and CD45RO. Less expression was found for CD15s, CD43, CD44, CD45RA, CD62L and HLA-DR. CD11a to c and CD18 were distributed in bimodal form on DLGL, part of the cells being negative. In summary, we found considerable differences between the cell surface marker profiles of DLGL and PBNK cells (subpopulations of the latter being separately analyzed).
