In exfoliative cytology, epithelial cells are removed and examined without any lasting damage to the tissue from which these cells are removed. why is there usually no lasting damage?

Answer;

Epithelial tissue is capable of regeneration.

Explanation;

-Exfoliative cytology is an important alternative to biopsy in certain situations. In exfoliative cytology, cells shed from body surfaces, such as the inside of the mouth, are collected and examined.

-This technique is useful only for the examination of surface cells and often requires additional cytological analysis to confirm the results. Epithelial cells are removed and examined without any lasting damage to the tissue from which these cells are removed because many epithelial tissues are capable of regeneration, that is, they are capable of rapidly replacing damaged and dead cells.
