Peripheral blood lymphocytes from normal subjects were studied for mouse rosette-forming cells (MRFC) and their relationship to surface immunoglobulins (SIg). The majority of MRFC expressed both SIgM and SIgD, although some dissociation between population showing SIgM+/MRFC- and SIgM-/MRFC+ could be seen. A similar pattern of association was found in human derived cultured cells of B lineage, but no simple correlation and the number of SIgM+ cells could be established. Increased percentages of MRFC were detected in two foetal livers but greater dissociation of MRFC and SIgM was shown. This heterogeneity of MRFC may be explained by a selective expression of this surface marker in the early stages of B lymphocyte differentiation.

Abstract
Peripheral blood lymphocytes from normal subjects were studied for mouse rosette-forming cells (MRFC) and their relationship to surface immunoglobulins (SIg). The majority of MRFC expressed both SIgM and SIgD, although some dissociation between population showing SIgM+/MRFC- and SIgM-/MRFC+ could be seen. A similar pattern of association was found in human derived cultured cells of B lineage, but no simple correlation and the number of SIgM+ cells could be established. Increased percentages of MRFC were detected in two foetal livers but greater dissociation of MRFC and SIgM was shown. This heterogeneity of MRFC may be explained by a selective expression of this surface marker in the early stages of B lymphocyte differentiation.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
