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.
