The distribution of cells of the monocytic-lineage in reactive lymph nodes and non-Hodgkin's lymphomata. Characterization using protein histochemistry, lectin binding and monoclonal antibodies.

In this study cells of putative monocytic origin have been investigated in lymph nodes, using a battery of cytochemical investigations on fixed and frozen tissue. In reactive lymph nodes involved in non-Hodgkin's lymphomata six types of presumed monocyte-derived cells have been identified on the basis of morphology and/or cytochemistry. These cells can be divided into two distinct groups. Certain cell types have distinctive distributions in reactive and non-Hodgkin's lymphomata and this taken in conjunction with their morphology and staining properties may give important clues to their function.
