The study investigates the expression of glycophorin A and spectrin in erythroid cells and their role at various differentiation stages.
Used specific antibodies for immunofluorescence to analyze human bone marrow and spleen cells from mice with induced anemia.
Identified erythroid precursor cells, specifically proerythroblasts, and assessed expression levels of glycophorin A and spectrin.
Investigated expression changes in the human tumor cell line K562 under various induction conditions.
In normal bone marrow, 50-60% of nucleated cells express glycophorin A and spectrin at all erythroid differentiation stages.
Bone marrow from patients with erythropoiesis block shows absence of glycophorin A and spectrin expressing nucleated cells.
In anemic mice, 70-80% of spleen cells stained positive for a sialoglycoprotein, compared to 1-2% in normal animals.
