Understanding Normoblasts: The Essential Role in Erythropoiesis and Hemoglobin Production

Understanding Normoblasts: The Essential Role in Erythropoiesis and Hemoglobin Production

Write a short note on normoblast.
Answer:

Normoblast

Normoblast is divided into three stages, i.e.

• Early normoblast
• Intermediate normoblast
• Late normoblast.
  • Early
  • Late.

Normoblasts

“Understanding normoblasts: Function and importance”

Early Normoblast

• It is 14-16µm in size.
• The size of the nucleus is small. No nucleoli is present. Condensation of chromatin is present.
• The cytoplasm is more in amount and is less basophilic.
• Active mitosis is present.

Intermediate Normoblast

• It is 10-14 µm in size.
• The size of the nucleus decreases as compared to early normoblast. There is more condensation of chromatin as compared to early normoblast.
• The cytoplasm is present in good amounts and is present with polychromatophilic staining.
• Hemoglobin starts appearing.
• Active mitosis is present.

Late Normoblast

• Early:
  • It is 8-10 µm in size.
  • The nucleus is very small with a chromatin dot and appears cart-wheel-shaped.
  • Cytoplasm staining increases markedly.
  • Hemoglobin further increases in amount.
  • Mitosis stops here.

• Late:
  • It is 7-8 µm in size.
  • The nucleus gets degenerated, is deeply stained, and is pyknotic.
  • Staining of cytoplasm increases and is more acidic.
  • Hemoglobin further increases in amount.
  • Mitosis is absent.
