Erythroblasts

Part of speech: noun

Definitions

1. A type of red blood cell precursor found in the bone marrow that is crucial for the development of mature red blood cells
2. These cells are characterized by their ability to synthesize hemoglobin and are an essential component in erythropoiesis
3. They play a vital role in the formation of red blood cells, by undergoing several stages of maturation before becoming fully functional erythrocytes

Etymology: "Erythroblasts" is the plural of "erythroblast," a term built from two Greek elements. The first, "erythro-," comes from Greek "erythros," meaning red, the same root that gives us "erythema" (redness of the skin). The second, "-blast," comes from Greek "blastos," meaning a bud or sprout, and it appears in scientific words for immature or developing cells, such as "osteoblast" and "fibroblast." Put together, the name describes exactly what the cell is: a developing precursor that will become a red blood cell. In the bone marrow, an erythroblast goes through several stages of maturation, shedding its nucleus and filling with hemoglobin on the way to becoming a mature erythrocytes. Because the word was assembled from classical roots to name a cell type discovered by modern microscopy, it is a coinage of the scientific era rather than an ancient term.
