hematoblast

hematoblast
A primitive, undifferentiated form of blood cell from which erythroblasts, lymphoblasts, myeloblasts, and other immature blood cells are derived; probably identical or closely similar to hemocytoblast and hemohistioblast; in normal bone marrow, present only in small numbers and difficult to identify in smears, inasmuch as hematoblasts are fragile and easily disintegrated; when marrow is hyperplastic, they may be observed in small groups. [hemato- + G. blastos, germ]
- Hayem h. obsolete term for platelet.
