Label	Id	Description
nongranular leukocyte	CL_0002087	[A leukocyte that lacks granules.]
eukaryotic cell	CL_0000255
proerythroblast	CL_0000547	[An immature, nucleated erythrocyte occupying the stage of erythropoeisis that follows formation of erythroid progenitor cells. This cell is CD71-positive, has both a nucleus and a nucleolus, and lacks hematopoeitic lineage markers.]
erythroid lineage cell	CL_0000764	[A immature or mature cell in the lineage leading to and including erythrocytes.]
basophilic erythroblast	CL_0000549	[A nucleated immature erythrocyte, having cytoplasm generally similar to that of the earlier proerythroblast but sometimes even more basophilic, and usually regular in outline. The nucleus is still relatively large, but the chromatin strands are thicker and more deeply staining, giving a coarser appearance; the nucleoli have disappeared. This cell is CD71-positive and lacks hematopoeitic lineage markers.]
erythroblast	CL_0000765	[A nucleated precursor of an erythrocyte that lacks hematopoietic lineage markers.]
polychromatophilic erythroblast	CL_0000550	[A nucleated, immature erythrocyte in which the nucleus occupies a relatively smaller part of the cell than in its precursor, the basophilic erythroblast. The cytoplasm is beginning to acquire hemoglobin and thus is no longer a purely basophilic, but takes on acidophilic aspects, which becomes progressively more marked as the cell matures. The chromatin of the nucleus is arranged in coarse, deeply staining clumps. This cell is CD71-positive and lacks hematopoeitic lineage markers.]
megakaryocyte progenitor cell	CL_0000553	[The earliest cytologically identifiable precursor in the thrombocytic series. This cell is capable of endomitosis and lacks expression of hematopoieitic lineage markers (lin-negative).]
myeloid lineage restricted progenitor cell	CL_0000839	[A progenitor cell restricted to the myeloid lineage.]
myeloid cell	CL_0000763	[A cell of the monocyte, granulocyte, mast cell, megakaryocyte, or erythroid lineage.]
megakaryocyte-erythroid progenitor cell	CL_0000050	[A progenitor cell committed to the megakaryocyte and erythroid lineages.]
orthochromatic erythroblast	CL_0000552	[The final stage of the nucleated, immature erythrocyte, before nuclear loss. Typically the cytoplasm is described as acidophilic, but it still shows a faint polychromatic tint. The nucleus is small and initially may still have coarse, clumped chromatin, as in its precursor, the polychromatophilic erythroblast, but ultimately it becomes pyknotic, and appears as a deeply staining, blue-black, homogeneous structureless mass. The nucleus is often eccentric and sometimes lobulated.]
promonocyte	CL_0000559	[A precursor in the monocytic series, being a cell intermediate in development between the monoblast and monocyte. This cell is CD11b-positive and has fine azurophil granules.]
monopoietic cell	CL_0002194	[A cell involved in the formation of a monocyte (monopoiesis).]
monoblast	CL_0000040	[A myeloid progenitor cell committed to the monocyte lineage. This cell is CD11b-positive, has basophilic cytoplasm, euchromatin, and the presence of a nucleolus.]
reticulocyte	CL_0000558	[An immature erythrocyte that changes the protein composition of its plasma membrane by exosome formation and extrusion. The types of protein removed differ between species though removal of the transferrin receptor is apparent in mammals and birds.]
granulocyte monocyte progenitor cell	CL_0000557	[A hematopoietic progenitor cell that is committed to the granulocyte and monocyte lineages. These cells are CD123-positive, and do not express Gata1 or Gata2 but do express C/EBPa, and Pu.1.]
megakaryocyte	CL_0000556	[A giant cell 50 to 100 micron in diameter, with a greatly lobulated nucleus, found in the bone marrow; mature blood platelets are released from its cytoplasm.]
nucleate erythrocyte	CL_0000562	[An erythrocyte having a nucleus.]
erythrocyte	CL_0000232	[A red blood cell. In mammals, mature erythrocytes are biconcave disks containing hemoglobin whose function is to transport oxygen.]
