Question
(A): Hepatocytes are labile cells (R): Hepatocytes can re enter the cell cycle and regenerate themselves a) Both A & R are correct and R is the reason for A b) Both A & R are correct but R is not reason for A c) A is correct R is incorrect d) A is incorrect R is correct (PTO)
Answer
Correct answer: d) A is incorrect R is correct (PTO)
A is incorrect, R is correct. Hepatocytes are classically classified as stable (quiescent, G0) cells, not labile cells — under normal physiological conditions they divide infrequently, but R correctly describes why they are grouped this way: they retain the capacity to re-enter the cell cycle and proliferate robustly in response to injury or loss of liver tissue (as seen in liver regeneration). Labile cells, by contrast, divide continuously throughout life (e.g., epithelium of the skin and gut, bone marrow cells).
