In response to excessive physiologic
stresses or pathologic stimuli the cell
may adapt, where a new changed
steady state is achieved preserving
cell viability.

CELLULAR ADAPTATIVE RESPONSE TO
INJURY
• Cellular adaptation is the result of a persistent stress
or injury
• Adaptive responses are potentially reversible once
the stress has been removed
• Some forms of adaptation may precede or progress
to malignancy
Types of cell adaptation:
1. Atrophy
2. Hypertrophy
3. Hyperplasia
4. Metaplasia
5. Dysplasia
