WebPolychromatophilia. Polychromatophilia refers to how blood cells look under a microscope when the cells are stained with special dyes. It means there is more staining than normal with certain dyes. The extra staining is due to an increased number of immature red blood cells (RBCs) called reticulocytes. These cells have a blue-colored center. WebAcanthocytes (o r spur cells) are spherical cells with blunt-tipped or club-shaped spicules of different lengths projecting from their surface at irregular intervals.
