For people who are not aware, these are known to be immature cells that can be found in the bone marrow. Those who would have these types of cells are those who are diagnosed with leukemia. The morphology of these cells is different from each other. Myeloblasts will be called as band cells.
The nucleus of this type of cell will be different from that of the lymphoblast wherein the nucleus will be round. For the Myeloblast, it will be a bit curved. Their sizes are also different from each other. A lymphoblast is known to be a bit smaller as it will only be up to 15 um while the myeloblast will be about 20 um.
Myeloblast is commonly called band cells, myeloblast is an immature cell of the bone marrow that develops into myelocyte. It is differentiated into basophils, eosinophils, and neutrophils. The nucleus of myeloblast is curved in shape and appears in the shape of S, V or C, it also contains granules in the cytoplasm. The diameter of the myeloblast is around 20 μm. Malfunctioning of myeloblasts leads to acute myeloblastic leukemia.
Lymphoblast is an immature lymphocyte; the nucleus is round in shape and does not contain cytoplasm granules. Lymphoblast can be differentiated into T and B lymphocytes when they undergo lymphopoiesis. The diameter is about 15 μm.
They are present in the bone marrow and thymus gland. Overproduction of lymphoblasts can lead to acute lymphoblastic leukemia.
