General description

Glycophorins A (GPA) and B (GPB) are major sialoglycoproteins of the human erythrocyte membrane which bear the antigenic determinants for the MN and SU blood groups. Glycophorins span the membrane and present their amino-terminal end to the extracellular surface of the human erythrocyte. The genetic array of expressed glycophorin surface antigens on erythrocytes defines the blood group phenotype of the individual. GPA is the carrier of blood group M and N specificities, while GPB accounts for S and U specificities. GPA and GPB provide the cells with a large mucin-like surface and it has been suggested this provides a barrier to cell fusion thus minimizing aggregation between red blood cells in the circulation. Anti-glycophorin A has been used to characterize erythroid cell development and in the diagnosis of erythroid leukemias.
Glycophorins A and B are major sialoglycoproteins expressed across the surface of the human erythrocyte membrane and contain the antigenic determinants that define the MNS blood group system. The high sialic acid content of glycophorin A contributes to the generation of a net negative surface charge across erythrocyte membranes that minimizes interactions between red blood cells and prevents their aggregation. Anti-glycophorin A has utility in identifying cells of the erythroid lineage.

Neoplastic erythroid proliferations may represent a diagnostic challenge owing to the difficulty in characterizing immature erythroblasts. Immunohistochemical expression of aldehyde dehydrogenase (ALDH), carbonic anhydrase isoenzyme I (CA I), and CD2-associated protein (CD2AP) was assessed in 66 bone marrow biopsy specimens

Histology assessment of erythroid precursors in bone marrow biopsies can be challenging under pathologic conditions and often requires ancillary studies. CD71 (transferring receptor-1) is known to be expressed in the earliest erythroid precursors, and has been useful for flow cytometry.

To investigate whether spectrin can be used as an immunohistochemical marker for erythroid precursors in routinely processed paraffin embedded bone marrow sections. Bone marrow biopsies and clot sections were stained with rabbit antihuman erythrocyte spectrin antibodies, specific for erythroid cells

The present study was designed to evaluate the lineage differentiation (particularly monocytic differentiation) of immature myeloid cells in granulocytic sarcoma (GS) by immunohistochemistry and correlate the results with lineage differentiation of blasts in the bone marrow and to determine the
