Previous studies have shown that many neutrophil (PMN) characteristics are heterogeneous but the origin of PMN heterogeneity is unknown. It is unclear if PMN functional heterogeneity is secondary to maturational differences or due to distinct subpopulations of cells that possess different functional capacities. The PMN 31D8 antigen is a useful probe for evaluation of PMN subpopulations. The maj...

Seven spontaneous BALB/cfC3H mouse mammary tumors were heterogeneous in expression of murine mammary tumor virus-associated cell surface antigens. To determine the basis of this heterogeneity, cells from spontaneous tumors and from five subpopulations isolated from a single spontaneous tumor were examined for expression of viral antigens under both conventional conditions and conditions known t...

Two of three monoclonal antibodies to tissue-specific antigens of isolated colonie glands revealed gland to gland heterogeneity of antigen expression in sections of the histologically normal colonie mucosa from patients with colorectal adenocarcinoma or various nonmalignant condi tions. A colon-specific goblet cell antigen (designated 3NM) was absent from rare, solitary glands randomly distribu...

We have investigated the antigenic heterogeneity of human glioma cells and its correlation with other parameters of tumor cell heterogeneity (karyotype, 2':3' cyclic nucleotide 3'-phosphohydrolase expression, in vitro morphology) using the established human glioma cell line D-54 MG and eight single-cell-derived clones. The panel of antibodies used included 3 previously described heterologous se...
