Cell cycle and apoptosis · USMLE Step 1

Which of the following is NOT a typical morphological feature of a cell undergoing apoptosis?

  1. Cell shrinkage and membrane blebbing
  2. Chromatin condensation and nuclear fragmentation
  3. Inflammatory cell infiltration and swelling
  4. Formation of apoptotic bodies
Show answer and explanation

Correct answer: Inflammatory cell infiltration and swelling

Unlike necrosis, apoptosis does not provoke inflammation or cause cell swelling; instead, cells shrink, condense chromatin, form apoptotic bodies, and are phagocytosed without eliciting an inflammatory response.
