Witrynamicronucleated immature (polychromatic) erythrocytes is the principal endpoint. The number of mature (normochromatic) erythrocytes in the peripheral blood that contain micronuclei among a given number of mature erythrocytes can also be used as the endpoint of the assay when animals are treated continuously for 4 weeks or more. 6. WitrynaWithin the bone marrow, all blood cells begin from a single cell type called a stem cell. The stem cell divides to form immature forms of red blood cells, white blood cells, or a platelet-producing cell. Those immature cells then divide again, mature even more, and ultimately become red blood cells, white blood cells, or platelets.
