erythroblast

Thân thiện

A scientist examines an erythroblast under a microscope.

Definition

Noun: A nucleated cell found in bone marrow that is a precursor to red blood cells (erythrocytes). It is an immature cell that undergoes several stages of development, losing its nucleus before maturing into a functional red blood cell.

Usage

This is a specialized biological and medical term. It is used to describe a specific stage in hematopoiesis (the formation of blood cells). * The bone marrow biopsy showed an increased number of erythroblasts. * The erythroblast is the last nucleated stage before the cell becomes a reticulocyte.

Advanced Usage

• Normoblast: A more mature, terminally differentiated stage of an erythroblast. The terms are sometimes used interchangeably, though "normoblast" often refers to the stage just before the nucleus is expelled.
  • The normoblast eventually extrudes its nucleus to become a reticulocyte.
• Erythroblastosis fetalis: A serious blood disorder in a fetus or newborn infant, often due to Rh incompatibility with the mother, characterized by the presence of erythroblasts in the circulating blood.
  • The condition erythroblastosis fetalis requires immediate medical treatment.

Variants and Related Words

• Erythroblastic (adjective): Pertaining to or resembling an erythroblast.
  • The patient exhibited an erythroblastic response to the anemia.
• Proerythroblast (noun): An earlier, less mature precursor cell that develops into an erythroblast.
• Erythropoiesis (noun): The process of producing red blood cells.

Synonyms

• Normoblast (in specific contexts)
• Red blood cell precursor
• Immature erythrocyte
