Plasma Cell "clockface" Nucleus

Nucleus has darker (heterochromatin) regions around periphery of nucleus separated by lighter (euchromatin) regions. This gives the stained nucleus the generic appearance of a "clock face" (not the correct scientific name).

  • Heterochromatin - tightly packed form of DNA
  • Euchromatin - loosely packed form of DNA.

Alternative nomenclature - activated B cell, plasma B cells, plasmocytes, effector B cells and B cell that is secreting antibody.

(Stain - Haematoxylin Eosin)
