has part has plasma membrane part develops from basophilic myelocyte immature basophil basophilic metamyelocyte FMA:84198 A basophil precursor in the granulocytic series, being a cell intermediate in development between a basophilic myelocyte and a band form basophil. The nucleus becomes indented where the indentation is smaller than half the distance to the farthest nuclear margin; chromatin becomes coarse and clumped; specific granules predominate while primary granules are rare. Markers are CD11b-positive, CD15-positive, CD16-positive, CD24-positive, CD33-positive, and CD13-positive. metamyelocyte reniform nucleus heterochromatin azurophil granule tertiary granule integrin alpha-M alpha-(1,3)-fucosyltransferase 4 low affinity immunoglobulin gamma Fc region receptor III CD33 molecule signal transducer CD24 aminopeptidase N
